Computer | The machine was about a century ahead of its time. All the parts for his machine had to be made by hand — this was a major problem for a device with thousands of parts. Eventually, the project was dissolved with the decision of the British Government to cease funding. Babbage's failure to complete the analytical engine can be chiefly attributed to difficulties not only of politics and financing, but also to his desire to develop an increasingly sophisticated computer and to move ahead faster than anyone else could follow. Nevertheless, his son, Henry Babbage, completed a simplified version of the analytical engine's computing unit (the mill) in 1888. He gave a successful demonstration of its use in computing tables in 1906. | When was the mill created by Henry Babbage? | 56fdcc3b19033b140034cd85 | 1888 | 653 | null | -1 | false |
Santa_Monica,_California | Classified as a Subtropical Mediterranean climate (Köppen Csb), Santa Monica enjoys an average of 310 days of sunshine a year. It is located in USDA plant hardiness zone 11a. Because of its location, nestled on the vast and open Santa Monica Bay, morning fog is a common phenomenon in May, June and early July (caused by ocean temperature variations and currents). Like other inhabitants of the greater Los Angeles area, residents have a particular terminology for this phenomenon: the "May Gray" and the "June Gloom". Overcast skies are common during June mornings, but usually the strong sun burns the fog off by noon. In the late winter/early summer, daily fog is a phenomenon too. It happens suddenly and it may last some hours or past sunset time. Nonetheless, it will sometimes stay cloudy and cool all day during June, even as other parts of the Los Angeles area enjoy sunny skies and warmer temperatures. At times, the sun can be shining east of 20th Street, while the beach area is overcast. As a general rule, the beach temperature is from 5 to 10 degrees Fahrenheit (3 to 6 degrees Celsius) cooler than it is inland during summer days, and 5–10 degrees warmer during winter nights. | What type of weather is common in April? | 5a2d593cf28ef0001a5264bd | null | -1 | morning fog | 247 | true |
Gothic_architecture | In Northern Germany, Netherlands, northern Poland, Denmark, and the Baltic countries local building stone was unavailable but there was a strong tradition of building in brick. The resultant style, Brick Gothic, is called "Backsteingotik" in Germany and Scandinavia and is associated with the Hanseatic League. In Italy, stone was used for fortifications, but brick was preferred for other buildings. Because of the extensive and varied deposits of marble, many buildings were faced in marble, or were left with undecorated façade so that this might be achieved at a later date. | What was the name of the building style that resulted from the use of brick? | 57269f5add62a815002e8b45 | Brick Gothic, is called "Backsteingotik" | 198 | null | -1 | false |
Georgian_architecture | Town terraced houses for all social classes remained resolutely tall and narrow, each dwelling occupying the whole height of the building. This contrasted with well-off continental dwellings, which had already begun to be formed of wide apartments occupying only one or two floors of a building; such arrangements were only typical in England when housing groups of batchelors, as in Oxbridge colleges, the lawyers in the Inns of Court or The Albany after it was converted in 1802. In the period in question, only in Edinburgh were working-class purpose-built tenements common, though lodgers were common in other cities. A curving crescent, often looking out at gardens or a park, was popular for terraces where space allowed. In early and central schemes of development, plots were sold and built on individually, though there was often an attempt to enforce some uniformity, but as development reached further out schemes were increasingly built as a uniform scheme and then sold. | What shape looking out over the street was popular for terraces? | 5a13966cc8eab200188dc9cd | null | -1 | curving crescent | 624 | true |
Friedrich_Hayek | Hayek displayed an intellectual and academic bent from a very young age. He read fluently and frequently before going to school. At his father's suggestion, Hayek, as a teenager, read the genetic and evolutionary works of Hugo de Vries and the philosophical works of Ludwig Feuerbach. In school Hayek was much taken by one instructor's lectures on Aristotle's ethics. In his unpublished autobiographical notes, Hayek recalled a division between him and his younger brothers who were only few years younger than him, but he believed that they were somehow of a different generation. He preferred to associate with adults. | What did Hayek conclude regarding his brothers? | 572a3e323f37b31900478811 | they were somehow of a different generation | 537 | null | -1 | false |
To_Kill_a_Mockingbird | The second part of the novel deals with what book reviewer Harding LeMay termed "the spirit-corroding shame of the civilized white Southerner in the treatment of the Negro". In the years following its release, many reviewers considered To Kill a Mockingbird a novel primarily concerned with race relations. Claudia Durst Johnson considers it "reasonable to believe" that the novel was shaped by two events involving racial issues in Alabama: Rosa Parks' refusal to yield her seat on a city bus to a white person, which sparked the 1955 Montgomery Bus Boycott, and the 1956 riots at the University of Alabama after Autherine Lucy and Polly Myers were admitted (Myers eventually withdrew her application and Lucy was expelled, but reinstated in 1980). In writing about the historical context of the novel's construction, two other literary scholars remark: "To Kill a Mockingbird was written and published amidst the most significant and conflict-ridden social change in the South since the Civil War and Reconstruction. Inevitably, despite its mid-1930s setting, the story told from the perspective of the 1950s voices the conflicts, tensions, and fears induced by this transition." | Many reviewers consider the second part of the book to be about what issue? | 56d198dce7d4791d0090206f | race relations | 291 | null | -1 | false |
Energy | In cosmology and astronomy the phenomena of stars, nova, supernova, quasars and gamma-ray bursts are the universe's highest-output energy transformations of matter. All stellar phenomena (including solar activity) are driven by various kinds of energy transformations. Energy in such transformations is either from gravitational collapse of matter (usually molecular hydrogen) into various classes of astronomical objects (stars, black holes, etc.), or from nuclear fusion (of lighter elements, primarily hydrogen). The nuclear fusion of hydrogen in the Sun also releases another store of potential energy which was created at the time of the Big Bang. At that time, according to theory, space expanded and the universe cooled too rapidly for hydrogen to completely fuse into heavier elements. This meant that hydrogen represents a store of potential energy that can be released by fusion. Such a fusion process is triggered by heat and pressure generated from gravitational collapse of hydrogen clouds when they produce stars, and some of the fusion energy is then transformed into sunlight. | What theory states that space expanded and the universe cooled too rapidly for hydrogen to completely fuse into heavier elements? | 5729f781af94a219006aa701 | Big Bang | 643 | null | -1 | false |
Copyright_infringement | Sometimes only partial compliance with license agreements is the cause. For example, in 2013, the US Army settled a lawsuit with Texas-based company Apptricity, which makes software that allows the army to track their soldiers in real time. In 2004, the US Army paid US$4.5 million for a license of 500 users, while allegedly installing the software for more than 9000 users; the case was settled for US$50 million. Major anti-piracy organizations, like the BSA, conduct software licensing audits regularly to ensure full compliance. | How many users weren't paid for in 2004? | 5acfcb7477cf76001a686044 | null | -1 | 500 | 299 | true |
George_VI | In 1940, Winston Churchill replaced Neville Chamberlain as Prime Minister, though personally George would have preferred to appoint Lord Halifax. After the King's initial dismay over Churchill's appointment of Lord Beaverbrook to the Cabinet, he and Churchill developed "the closest personal relationship in modern British history between a monarch and a Prime Minister". Every Tuesday for four and a half years from September 1940, the two men met privately for lunch to discuss the war in secret and with frankness. | Who was Lord Halifax in 1940? | 5a36b43195360f001af1b30b | null | -1 | Neville Chamberlain | 36 | true |
Palermo | The city was founded in 734 BC by the Phoenicians as Ziz ('flower'). Palermo then became a possession of Carthage, before becoming part of the Roman Republic, the Roman Empire and eventually part of the Byzantine Empire, for over a thousand years. The Greeks named the city Panormus meaning 'complete port'. From 831 to 1072 the city was under Arab rule during the Emirate of Sicily when the city first became a capital. The Arabs shifted the Greek name into Balarm, the root for Palermo's present-day name. Following the Norman reconquest, Palermo became the capital of a new kingdom (from 1130 to 1816), the Kingdom of Sicily and the capital of the Holy Roman Empire under Frederick II Holy Roman Emperor and Conrad IV of Germany, King of the Romans. Eventually Sicily would be united with the Kingdom of Naples to form the Kingdom of the Two Sicilies until the Italian unification of 1860. | In what year was Palermo founded? | 5729478f6aef051400154c56 | 734 BC | 24 | null | -1 | false |
Aspirated_consonant | In phonetics, aspiration is the strong burst of breath that accompanies either the release or, in the case of preaspiration, the closure of some obstruents. In English, aspirated consonants are allophones in complementary distribution with their unaspirated counterparts, but in some other languages, notably most Indian and East Asian languages, the difference is contrastive. | Aspirated consonants are what in English? | 56e03fd2231d4119001ac014 | allophones | 194 | null | -1 | false |
Space_Race | Three weeks later, on May 5, 1961, Alan Shepard became the first American in space, launched in a ballistic trajectory on Mercury-Redstone 3, in a spacecraft he named Freedom 7. Though he did not achieve orbit like Gagarin, he was the first person to exercise manual control over his spacecraft's attitude and retro-rocket firing. After his successful return, Shepard was celebrated as a national hero, honored with parades in Washington, New York and Los Angeles, and received the NASA Distinguished Service Medal from President John F. Kennedy. | The first person to have control over driving their spacecraft was whom? | 56e0f229231d4119001ac4b5 | Alan Shepard | 35 | null | -1 | false |
Child_labour | Similarly, in 1996, member countries of the European Union, per Directive 94/33/EC, agreed to a number of exceptions for young people in its child labour laws. Under these rules, children of various ages may work in cultural, artistic, sporting or advertising activities if authorised by the competent authority. Children above the age of 13 may perform light work for a limited number of hours per week in other economic activities as defined at the discretion of each country. Additionally, the European law exception allows children aged 14 years or over to work as part of a work/training scheme. The EU Directive clarified that these exceptions do not allow child labour where the children may experience harmful exposure to dangerous substances. Nonetheless, many children under the age of 13 do work, even in the most developed countries of the EU. For instance, a recent study showed over a third of Dutch twelve-year-old kids had a job, the most common being babysitting. | What age were children able to take part in European training programs? | 5727985b708984140094e1c3 | aged 14 years or over | 536 | null | -1 | false |
Gregorian_calendar | Prior to 1917, Turkey used the lunar Islamic calendar with the Hegira era for general purposes and the Julian calendar for fiscal purposes. The start of the fiscal year was eventually fixed at 1 March and the year number was roughly equivalent to the Hegira year (see Rumi calendar). As the solar year is longer than the lunar year this originally entailed the use of "escape years" every so often when the number of the fiscal year would jump. From 1 March 1917 the fiscal year became Gregorian, rather than Julian. On 1 January 1926 the use of the Gregorian calendar was extended to include use for general purposes and the number of the year became the same as in other countries. | What was used to set the year number? | 5a36fffb95360f001af1b3c1 | null | -1 | the Hegira year | 247 | true |
Planck_constant | The assumption that black-body radiation is thermal leads to an accurate prediction: the total amount of emitted energy goes up with the temperature according to a definite rule, the Stefan–Boltzmann law (1879–84). But it was also known that the colour of the light given off by a hot object changes with the temperature, so that "white hot" is hotter than "red hot". Nevertheless, Wilhelm Wien discovered the mathematical relationship between the peaks of the curves at different temperatures, by using the principle of adiabatic invariance. At each different temperature, the curve is moved over by Wien's displacement law (1893). Wien also proposed an approximation for the spectrum of the object, which was correct at high frequencies (short wavelength) but not at low frequencies (long wavelength). It still was not clear why the spectrum of a hot object had the form that it has (see diagram). | What color is hotter than "red hot"? | 572925caaf94a219006aa106 | white hot | 331 | null | -1 | false |
Wayback_Machine | In Europe the Wayback Machine could be interpreted as violating copyright laws. Only the content creator can decide where their content is published or duplicated, so the Archive would have to delete pages from its system upon request of the creator. The exclusion policies for the Wayback Machine may be found in the FAQ section of the site. The Wayback Machine also retroactively respects robots.txt files, i.e., pages that currently are blocked to robots on the live web temporarily will be made unavailable from the archives as well. | What would the Internet Archive have to do if requested by someone whose content is available on Wayback Machine? | 56ddd0509a695914005b95ed | delete pages from its system | 193 | null | -1 | false |
Han_dynasty | Evidence found in Chinese literature, and archaeological evidence, show that cartography existed in China before the Han. Some of the earliest Han maps discovered were ink-penned silk maps found amongst the Mawangdui Silk Texts in a 2nd-century-BC tomb. The general Ma Yuan created the world's first known raised-relief map from rice in the 1st century AD. This date could be revised if the tomb of Qin Shi Huang is excavated and the account in the Records of the Grand Historian concerning a model map of the empire is proven to be true. | What textile were some of the early Han maps made from? | 572fad40b2c2fd1400568321 | silk | 179 | null | -1 | false |
New_Haven,_Connecticut | Lighthouse Point Park, a public beach run by the city, was a popular tourist destination during the Roaring Twenties, attracting luminaries of the period such as Babe Ruth and Ty Cobb. The park remains popular among New Haveners, and is home to the Five Mile Point Lighthouse, constructed in 1847, and the Lighthouse Point Carousel, constructed in 1916. Five Mile Point Light was decommissioned in 1877 following the construction of Southwest Ledge Light at the entrance of the harbor, which remains in service to this day. Both of the lighthouses and the carousel are listed on the National Register of Historic Places. | Throughout the Roaring Twenties, what public beach in New Haven was a favored destination for tourists? | 5727cedf2ca10214002d96fa | Lighthouse Point Park | 0 | null | -1 | false |
British_Empire | The last decades of the 19th century saw concerted political campaigns for Irish home rule. Ireland had been united with Britain into the United Kingdom of Great Britain and Ireland with the Act of Union 1800 after the Irish Rebellion of 1798, and had suffered a severe famine between 1845 and 1852. Home rule was supported by the British Prime minister, William Gladstone, who hoped that Ireland might follow in Canada's footsteps as a Dominion within the empire, but his 1886 Home Rule bill was defeated in Parliament. Although the bill, if passed, would have granted Ireland less autonomy within the UK than the Canadian provinces had within their own federation, many MPs feared that a partially independent Ireland might pose a security threat to Great Britain or mark the beginning of the break-up of the empire. A second Home Rule bill was also defeated for similar reasons. A third bill was passed by Parliament in 1914, but not implemented because of the outbreak of the First World War leading to the 1916 Easter Rising. | When was a Home Rule bill passed? | 57267c12dd62a815002e86c5 | 1914 | 923 | null | -1 | false |
Oklahoma | All of the state frequently experiences temperatures above 100 °F (38 °C) or below 0 °F (−18 °C), though below-zero temperatures are rare in south-central and southeastern Oklahoma. Snowfall ranges from an average of less than 4 inches (10 cm) in the south to just over 20 inches (51 cm) on the border of Colorado in the panhandle. The state is home to the Storm Prediction Center, the National Severe Storms Laboratory, and the Warning Decision Training Branch, all part of the National Weather Service and located in Norman. Oklahoma's highest recorded temperature of 120 °F (49 °C) was recorded at Tipton on June 27, 1994 and the lowest recorded temperature of −31 °F (−35 °C) was recorded at Nowata on February 10, 2011. | What was Oklahoma's record high temperature? | 5727d27f4b864d1900163dea | 120 °F | 570 | null | -1 | false |
Guam | Guam's climate is characterized as tropical marine moderated by seasonal northeast trade winds. The weather is generally very warm and humid with little seasonal temperature variation. The mean high temperature is 86 °F (30 °C) and mean low is 76 °F (24 °C) with an average annual rainfall of 96 inches (2,180 mm). The dry season runs from December to June. The remaining months (July to November) constitute the rainy season. The months of January and February are considered the coolest months of the year with overnight low temperatures of 70–75 °F (21–24 °C) and low humidity levels. The highest temperature ever recorded in Guam was 96 °F (36 °C) on April 18, 1971 and April 1, 1990, and the lowest temperature ever recorded was 65 °F (18 °C) on February 8, 1973. | What is the average annual rainfall of Guam? | 572b521ebe1ee31400cb8323 | 96 inches (2,180 mm) | 293 | null | -1 | false |
Cork_(city) | There are a variety of watersports in Cork, including rowing and sailing. There are five rowing clubs training on the river Lee, including Shandon BC, UCC RC, Pres RC, Lee RC, and Cork BC. Naomhóga Chorcaí is a rowing club whose members row traditional naomhóga on the Lee in occasional competitions. The "Ocean to City" race has been held annually since 2005, and attracts teams and boats from local and visiting clubs who row the 24 kilometres (15 mi) from Crosshaven into Cork city centre. The decision to move the National Rowing Center to Inniscarra has boosted numbers involved in the sport.[citation needed] Cork's maritime sailing heritage is maintained through its sailing clubs. The Royal Cork Yacht Club located in Crosshaven (outside the city) is the world's oldest yacht club, and "Cork Week" is a notable sailing event. | What has reduced numbers involved rowing? | 5a5d75f35e8782001a9d5f3c | null | -1 | The decision to move the National Rowing Center to Inniscarra | 493 | true |
Dutch_Republic | During the Dutch Golden Age in the late 16th century onward, the Dutch Republic dominated world trade in the 17th century, conquering a vast colonial empire and operating the largest fleet of merchantmen of any nation. The County of Holland was the wealthiest and most urbanized region in the world. | During the 17th century what did Holland conquer? | 5a1cbf334ea40d0018b06ef5 | null | -1 | a vast colonial empire | 134 | true |
Railway_electrification_system | In the United States, 25 Hz, a once-common industrial power frequency is used on Amtrak's 25 Hz traction power system at 12 kV on the Northeast Corridor between Washington, D.C. and New York City and on the Keystone Corridor between Harrisburg, Pennsylvania and Philadelphia. SEPTA's 25 Hz traction power system uses the same 12 kV voltage on the catenary in Northeast Philadelphia. This allows for the trains to operate on both the Amtrak and SEPTA power systems. Apart from having an identical catenary voltage, the power distribution systems of Amtrak and SEPTA are very different. The Amtrak power distribution system has a 138 kV transmission network that provides power to substations which then transform the voltage to 12 kV to feed the catenary system. The SEPTA power distribution system uses a 2:1 ratio autotransformer system, with the catenary fed at 12 kV and a return feeder wire fed at 24 kV. The New York, New Haven and Hartford Railroad used an 11 kV system between New York City and New Haven, Connecticut which was converted to 12.5 kV 60 Hz in 1987. | What uses a 1:2 ratio autotransformer? | 5acd858a07355d001abf456a | null | -1 | The SEPTA power distribution system | 762 | true |
Saint_Helena | Imported Chinese labourers arrived in 1810, reaching a peak of 618 in 1818, after which numbers were reduced. Only a few older men remained after the British Crown took over the government of the island from the East India Company in 1834. The majority were sent back to China, although records in the Cape suggest that they never got any farther than Cape Town. There were also a very few Indian lascars who worked under the harbour master. | What year did importation of Chinese Laborers peak? | 56e06a5e231d4119001ac0d9 | 1818 | 70 | null | -1 | false |
Kievan_Rus%27 | The Chronicle provides a mythic tale of Oleg's death. A sorcerer prophesies that the death of the Grand Prince would be associated with a certain horse. Oleg has the horse sequestered, and it later dies. Oleg goes to visit the horse and stands over the carcass, gloating that he had outlived the threat, when a snake strikes him from among the bones, and he soon becomes ill and dies. The Chronicle reports that Prince Igor succeeded Oleg in 913, and after some brief conflicts with the Drevlians and the Pechenegs, a period of peace ensued for over twenty years. | Who conquered and killed Oleg? | 5ad00aa277cf76001a6867ec | null | -1 | Prince Igor | 412 | true |
Humanism | Renaissance humanism was an intellectual movement in Europe of the later Middle Ages and the Early Modern period. The 19th-century German historian Georg Voigt (1827–91) identified Petrarch as the first Renaissance humanist. Paul Johnson agrees that Petrarch was "the first to put into words the notion that the centuries between the fall of Rome and the present had been the age of Darkness". According to Petrarch, what was needed to remedy this situation was the careful study and imitation of the great classical authors. For Petrarch and Boccaccio, the greatest master was Cicero, whose prose became the model for both learned (Latin) and vernacular (Italian) prose. | When did the first wave of Humanism reach Europe? | 57327da60fdd8d15006c6b25 | Middle Ages and the Early Modern period | 73 | null | -1 | false |
Eritrea | The Aksumites erected a number of large stelae, which served a religious purpose in pre-Christian times. One of these granite columns, the obelisk of Aksum, is the largest such structure in the world, standing at 90 feet. Under Ezana (fl. 320–360), Aksum later adopted Christianity. In the 7th century, early Muslims from Mecca also sought refuge from Quraysh persecution by travelling to the kingdom, a journey known in Islamic history as the First Hijra. It is also the alleged resting place of the Ark of the Covenant and the purported home of the Queen of Sheba. | What purpose did stelae serve? | 570db00216d0071400510ce1 | religious | 63 | null | -1 | false |
Apollo | After they each performed, both were deemed equal until Apollo decreed they play and sing at the same time. As Apollo played the lyre, this was easy to do. Marsyas could not do this, as he only knew how to use the flute and could not sing at the same time. Apollo was declared the winner because of this. Apollo flayed Marsyas alive in a cave near Celaenae in Phrygia for his hubris to challenge a god. He then nailed Marsyas' shaggy skin to a nearby pine-tree. Marsyas' blood turned into the river Marsyas. | What instrument did Apolo play? | 5728df9aff5b5019007da89c | lyre | 129 | null | -1 | false |
Napoleon | Critics argue Napoleon's true legacy must reflect the loss of status for France and needless deaths brought by his rule: historian Victor Davis Hanson writes, "After all, the military record is unquestioned—17 years of wars, perhaps six million Europeans dead, France bankrupt, her overseas colonies lost." McLynn notes that, "He can be viewed as the man who set back European economic life for a generation by the dislocating impact of his wars." However, Vincent Cronin replies that such criticism relies on the flawed premise that Napoleon was responsible for the wars which bear his name, when in fact France was the victim of a series of coalitions which aimed to destroy the ideals of the Revolution. | Approximately how many Europeans dead does Victor Davis Hanson assert are part of Napoleon's military record? | 5726f25ff1498d1400e8f0b6 | six million | 233 | null | -1 | false |
United_States_dollar | There is ongoing debate about whether central banks should target zero inflation (which would mean a constant value for the U.S. dollar over time) or low, stable inflation (which would mean a continuously but slowly declining value of the dollar over time, as is the case now). Although some economists are in favor of a zero inflation policy and therefore a constant value for the U.S. dollar, others contend that such a policy limits the ability of the central bank to control interest rates and stimulate the economy when needed. | A zero inflation policy would limit who's influence and ability to react? | 5709bb3ded30961900e8445b | central bank | 455 | null | -1 | false |
Napoleon | Following the Ulm Campaign, French forces managed to capture Vienna in November. The fall of Vienna provided the French a huge bounty as they captured 100,000 muskets, 500 cannons, and the intact bridges across the Danube. At this critical juncture, both Tsar Alexander I and Holy Roman Emperor Francis II decided to engage Napoleon in battle, despite reservations from some of their subordinates. Napoleon sent his army north in pursuit of the Allies, but then ordered his forces to retreat so that he could feign a grave weakness. Desperate to lure the Allies into battle, Napoleon gave every indication in the days preceding the engagement that the French army was in a pitiful state, even abandoning the dominant Pratzen Heights near the village of Austerlitz. At the Battle of Austerlitz, in Moravia on 2 December, he deployed the French army below the Pratzen Heights and deliberately weakened his right flank, enticing the Allies to launch a major assault there in the hopes of rolling up the whole French line. A forced march from Vienna by Marshal Davout and his III Corps plugged the gap left by Napoleon just in time. Meanwhile, the heavy Allied deployment against the French right weakened their center on the Pratzen Heights, which was viciously attacked by the IV Corps of Marshal Soult. With the Allied center demolished, the French swept through both enemy flanks and sent the Allies fleeing chaotically, capturing thousands of prisoners in the process. The battle is often seen as a tactical masterpiece because of the near-perfect execution of a calibrated but dangerous plan — of the same stature as Cannae, the celebrated triumph by Hannibal some 2000 years before. | When was the Battle of Austerlitz fought? | 572692aef1498d1400e8e42f | 2 December | 808 | null | -1 | false |
Transistor | The thermionic triode, a vacuum tube invented in 1907, enabled amplified radio technology and long-distance telephony. The triode, however, was a fragile device that consumed a lot of power. Physicist Julius Edgar Lilienfeld filed a patent for a field-effect transistor (FET) in Canada in 1925, which was intended to be a solid-state replacement for the triode. Lilienfeld also filed identical patents in the United States in 1926 and 1928. However, Lilienfeld did not publish any research articles about his devices nor did his patents cite any specific examples of a working prototype. Because the production of high-quality semiconductor materials was still decades away, Lilienfeld's solid-state amplifier ideas would not have found practical use in the 1920s and 1930s, even if such a device had been built. In 1934, German inventor Oskar Heil patented a similar device. | When was the thermionic triode invented? | 572edbc103f9891900756a95 | 1907 | 49 | null | -1 | false |
Madrasa | Nevertheless, Makdisi has asserted that the European university borrowed many of its features from the Islamic madrasa, including the concepts of a degree and doctorate. Makdisi and Hugh Goddard have also highlighted other terms and concepts now used in modern universities which most likely have Islamic origins, including "the fact that we still talk of professors holding the 'Chair' of their subject" being based on the "traditional Islamic pattern of teaching where the professor sits on a chair and the students sit around him", the term 'academic circles' being derived from the way in which Islamic students "sat in a circle around their professor", and terms such as "having 'fellows', 'reading' a subject, and obtaining 'degrees', can all be traced back" to the Islamic concepts of aṣḥāb ('companions, as of Muhammad'), qirāʼah ('reading aloud the Qur'an') and ijāzah ('licence [to teach]') respectively. Makdisi has listed eighteen such parallels in terminology which can be traced back to their roots in Islamic education. Some of the practices now common in modern universities which Makdisi and Goddard trace back to an Islamic root include "practices such as delivering inaugural lectures, wearing academic robes, obtaining doctorates by defending a thesis, and even the idea of academic freedom are also modelled on Islamic custom." The Islamic scholarly system of fatwá and ijmāʻ, meaning opinion and consensus respectively, formed the basis of the "scholarly system the West has practised in university scholarship from the Middle Ages down to the present day." According to Makdisi and Goddard, "the idea of academic freedom" in universities was also "modelled on Islamic custom" as practised in the medieval Madrasa system from the 9th century. Islamic influence was "certainly discernible in the foundation of the first deliberately planned university" in Europe, the University of Naples Federico II founded by Frederick II, Holy Roman Emperor in 1224. | What institutions have been considered to get no its ideas from madaris? | 5ace7f7832bba1001ae4a84f | null | -1 | European university | 44 | true |
Israel | In July 2007, American business magnate and investor Warren Buffett's holding company Berkshire Hathaway bought an Israeli company, Iscar, its first non-U.S. acquisition, for $4 billion. Since the 1970s, Israel has received military aid from the United States, as well as economic assistance in the form of loan guarantees, which now account for roughly half of Israel's external debt. Israel has one of the lowest external debts in the developed world, and is a net lender in terms of net external debt (the total value of assets vs. liabilities in debt instruments owed abroad), which in December 2015[update] stood at a surplus of US$118 billion. | When did United States begin to provide foreign aid to Israel? | 5725ce66ec44d21400f3d5e0 | 1970s | 197 | null | -1 | false |
2008_Summer_Olympics_torch_relay | Prior to the rally, seven anti-China protestors were arrested in Hanoi after unfurling a banner and shouting "Boycott the Beijing Olympics" through a loudhailer at a market. A Vietnamese American was deported for planning protests against the torch, while a prominent blogger, Điếu Cày (real name Nguyễn Văn Hải), who blogged about protests around the world and who called for demonstrations in Vietnam, was arrested on charges of tax evasion. Outside Vietnam, there were protests by overseas Vietnamese in Paris, San Francisco and Canberra. Lê Minh Phiếu, a torchbearer who is a Vietnamese law student studying in France, wrote a letter to the president of the International Olympic Committee protesting China's "politicisation of the Olympics", citing maps of the torch relay at the official Beijing Olympic website depicting the disputed islands as Chinese territory and posted it on his blog. One day before the relay was to start, the official website appeared to have been updated to remove the disputed islands and dotted lines marking China's maritime claims in the South China Sea. | Which blogger calling for demonstrations was arrested for tax evasion? | 56d973fedc89441400fdb499 | Điếu Cày | 277 | null | -1 | false |
Samurai | The rival of Takeda Shingen (1521–1573) was Uesugi Kenshin (1530–1578), a legendary Sengoku warlord well-versed in the Chinese military classics and who advocated the "way of the warrior as death". Japanese historian Daisetz Teitaro Suzuki describes Uesugi's beliefs as: "Those who are reluctant to give up their lives and embrace death are not true warriors.... Go to the battlefield firmly confident of victory, and you will come home with no wounds whatever. Engage in combat fully determined to die and you will be alive; wish to survive in the battle and you will surely meet death. When you leave the house determined not to see it again you will come home safely; when you have any thought of returning you will not return. You may not be in the wrong to think that the world is always subject to change, but the warrior must not entertain this way of thinking, for his fate is always determined." | What did Uesugi encourage? | 5728f4a76aef0514001548bb | the "way of the warrior as death" | 163 | null | -1 | false |
Orthodox_Judaism | In contrast to the general American Jewish community, which is dwindling due to low fertility and high intermarriage and assimilation rates, the Orthodox Jewish community of the United States is growing rapidly. Among Orthodox Jews, the fertility rate stands at about 4.1 children per family, as compared to 1.9 children per family among non-Orthodox Jews, and intermarriage among Orthodox Jews is practically non-existent, standing at about 2%, in contrast to a 71% intermarriage rate among non-Orthodox Jews. In addition, Orthodox Judaism has a growing retention rate; while about half of those raised in Orthodox homes previously abandoned Orthodox Judaism, that number is declining. According to The New York Times, the high growth rate of Orthodox Jews will eventually render them the dominant demographic force in New York Jewry. | What is the fertility rate of American Jewish communities? | 5a57e4aa770dc0001aeefe83 | null | -1 | 4.1 children per family | 268 | true |
Cubism | In contrast, the Salon Cubists built their reputation primarily by exhibiting regularly at the Salon d'Automne and the Salon des Indépendants, both major non-academic Salons in Paris. They were inevitably more aware of public response and the need to communicate. Already in 1910 a group began to form which included Metzinger, Gleizes, Delaunay and Léger. They met regularly at Henri le Fauconnier's studio near the Boulevard de Montparnasse. These soirées often included writers such as Guillaume Apollinaire and André Salmon. Together with other young artists, the group wanted to emphasise a research into form, in opposition to the Neo-Impressionist emphasis on color. | What did the group meeting at Fauconnier's studio want to focus on? | 5726c4aaf1498d1400e8eab6 | research into form, in opposition to the Neo-Impressionist emphasis on color. | 596 | null | -1 | false |
Tennessee | After disenfranchisement of blacks, the GOP in Tennessee was historically a sectional party supported by whites only in the eastern part of the state. In the 20th century, except for two nationwide Republican landslides of the 1920s (in 1920, when Tennessee narrowly supported Warren G. Harding over Ohio Governor James Cox, and in 1928, when it more decisively voted for Herbert Hoover over New York Governor Al Smith, a Catholic), the state was part of the Democratic Solid South until the 1950s. In that postwar decade, it twice voted for Republican Dwight D. Eisenhower, former Allied Commander of the Armed Forces during World War II. Since then, more of the state's voters have shifted to supporting Republicans, and Democratic presidential candidates have carried Tennessee only four times. | What religion was the Democratic presidential candidate that Tennessee voted against in 1928? | 572c9bb7f182dd1900d7c7f7 | Catholic | 422 | null | -1 | false |
Idealism | Pluralistic idealism such as that of Gottfried Leibniz takes the view that there are many individual minds that together underlie the existence of the observed world and make possible the existence of the physical universe. Unlike absolute idealism, pluralistic idealism does not assume the existence of a single ultimate mental reality or "Absolute". Leibniz' form of idealism, known as Panpsychism, views "monads" as the true atoms of the universe and as entities having perception. The monads are "substantial forms of being",elemental, individual, subject to their own laws, non-interacting, each reflecting the entire universe. Monads are centers of force, which is substance while space, matter and motion are phenomenal and their form and existence is dependent on the simple and immaterial monads. There is a pre-established harmony established by God, the central monad, between the world in the minds of the monads and the external world of objects. Leibniz's cosmology embraced traditional Christian Theism. The English psychologist and philosopher James Ward inspired by Leibniz had also defended a form of pluralistic idealism. According to Ward the universe is composed of "psychic monads" of different levels, interacting for mutual self- betterment. | Who was a notable disciple of Leibniz? | 572b7982be1ee31400cb83c0 | James Ward | 1,060 | null | -1 | false |
British_Empire | After the German occupation of France in 1940, Britain and the empire stood alone against Germany, until the entry of the Soviet Union to the war in 1941. British Prime Minister Winston Churchill successfully lobbied President Franklin D. Roosevelt for military aid from the United States, but Roosevelt was not yet ready to ask Congress to commit the country to war. In August 1941, Churchill and Roosevelt met and signed the Atlantic Charter, which included the statement that "the rights of all peoples to choose the form of government under which they live" should be respected. This wording was ambiguous as to whether it referred to European countries invaded by Germany, or the peoples colonised by European nations, and would later be interpreted differently by the British, Americans, and nationalist movements. | When was the Atlantic Charter signed? | 57268766dd62a815002e8843 | August 1941 | 371 | null | -1 | false |
Arnold_Schwarzenegger | Schwarzenegger's early victories included repealing an unpopular increase in the vehicle registration fee as well as preventing driver's licenses being given out to illegal immigrants, but later he began to feel the backlash when powerful state unions began to oppose his various initiatives. Key among his reckoning with political realities was a special election he called in November 2005, in which four ballot measures he sponsored were defeated. Schwarzenegger accepted personal responsibility for the defeats and vowed to continue to seek consensus for the people of California. He would later comment that "no one could win if the opposition raised 160 million dollars to defeat you". The U.S. Supreme Court later found the public employee unions' use of compulsory fundraising during the campaign had been illegal in Knox v. Service Employees International Union, Local 1000. | In what month of 2005 did Schwarzenegger hold a special election? | 56debe163277331400b4d701 | November | 378 | null | -1 | false |
John_Kerry | After Kerry's third qualifying wound, he was entitled per Navy regulations to reassignment away from combat duties. Kerry's preferred choice for reassignment was as a military aide in Boston, New York or Washington, D.C. On April 11, 1969, he reported to the Brooklyn-based Atlantic Military Sea Transportation Service, where he would remain on active duty for the following year as a personal aide to an officer, Rear Admiral Walter Schlech. On January 1, 1970 Kerry was temporarily promoted to full Lieutenant. Kerry had agreed to an extension of his active duty obligation from December 1969 to August 1970 in order to perform Swift Boat duty. John Kerry was on active duty in the United States Navy from August 1966 until January 1970. He continued to serve in the Naval Reserve until February 1978. | Which wound allowed Kerry to leave combat duty? | 572aadc2be1ee31400cb8153 | third | 14 | null | -1 | false |
Film_speed | Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a slow film. Highly sensitive films are correspondingly termed fast films. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor. | What types of film are considered fast films? | 57263b5b38643c19005ad33e | Highly sensitive films | 204 | null | -1 | false |
Canadian_football | The Grey Cup was established in 1909 after being donated by Albert Grey, 4th Earl Grey, The Governor General of Canada as the championship of teams under the CRU for the Rugby Football Championship of Canada. Initially an amateur competition, it eventually became dominated by professional teams in the 1940s and early 1950s. The Ontario Rugby Football Union, the last amateur organization to compete for the trophy, withdrew from competition in 1954. The move ushered in the modern era of Canadian professional football. | What position was held by the Ontario Rugby Football Union? | 5a0f455bdecec90018475545 | null | -1 | The Governor General of Canada | 88 | true |
Antibiotics | In 1939, coinciding with the start of World War II, Rene Dubos reported the discovery of the first naturally derived antibiotic, tyrothricin, a compound of 20% gramicidin and 80% tyrocidine, from B. brevis. It was one of the first commercially manufactured antibiotics universally and was very effective in treating wounds and ulcers during World War II. Gramicidin, however, could not be used systemically because of toxicity. Tyrocidine also proved too toxic for systemic usage. Research results obtained during that period were not shared between the Axis and the Allied powers during the war. | When was Gramicidin created? | 5a65e676c2b11c001a425dda | null | -1 | 1939 | 3 | true |
Planck_constant | The photoelectric effect is the emission of electrons (called "photoelectrons") from a surface when light is shone on it. It was first observed by Alexandre Edmond Becquerel in 1839, although credit is usually reserved for Heinrich Hertz, who published the first thorough investigation in 1887. Another particularly thorough investigation was published by Philipp Lenard in 1902. Einstein's 1905 paper discussing the effect in terms of light quanta would earn him the Nobel Prize in 1921, when his predictions had been confirmed by the experimental work of Robert Andrews Millikan. The Nobel committee awarded the prize for his work on the photo-electric effect, rather than relativity, both because of a bias against purely theoretical physics not grounded in discovery or experiment, and dissent amongst its members as to the actual proof that relativity was real. | Who published the first thorough investigation of the photoelectric effect? | 57292b05af94a219006aa14d | Heinrich Hertz | 223 | null | -1 | false |
Child_labour | There were even Verdingkinder auctions where children were handed over to the farmer asking the least amount of money from the authorities, thus securing cheap labour for his farm and relieving the authority from the financial burden of looking after the children. In the 1930s 20% of all agricultural labourers in the Canton of Bern were children below the age of 15. Swiss municipality guardianship authorities acted so, commonly tolerated by federal authorities, to the 1960s, not all of them of course, but usually communities affected of low taxes in some Swiss cantons Swiss historian Marco Leuenberger investigated, that in 1930 there were some 35,000 indentured children, and between 1920 and 1970 more than 100,000 are believed to have been placed with families or homes. 10,000 Verdingkinder are still alive. Therefore, the so-called Wiedergutmachungsinitiative was started in April 2014. In April 2014 the collection of targeted at least authenticated 100,000 signatures of Swiss citizens has started, and still have to be collected to October 2015. | How many Swiss citizen signatures were collected? | 572795a6dd62a815002ea130 | 100,000 | 963 | null | -1 | false |
Greeks | A distinct Greek political identity re-emerged in the 11th century in educated circles and became more forceful after the fall of Constantinople to the Crusaders of the Fourth Crusade in 1204, so that when the empire was revived in 1261, it became in many ways a Greek national state. That new notion of nationhood engendered a deep interest in the classical past culminating in the ideas of the Neoplatonist philosopher Gemistus Pletho, who abandoned Christianity. However, it was the combination of Orthodox Christianity with a specifically Greek identity that shaped the Greeks' notion of themselves in the empire's twilight years. The interest in the Classical Greek heritage was complemented by a renewed emphasis on Greek Orthodox identity, which was reinforced in the late Medieval and Ottoman Greeks' links with their fellow Orthodox Christians in the Russian Empire. These were further strengthened following the fall of the Empire of Trebizond in 1461, after which and until the second Russo-Turkish War of 1828-29 hundreds of thousands of Pontic Greeks fled or migrated from the Pontic Alps and Armenian Highlands to southern Russia and the Russian South Caucasus (see also Greeks in Russia, Greeks in Armenia, Greeks in Georgia, and Caucasian Greeks). | What was bolstered by the the final downward spiral of the Empire of Trebizond ? | 572fbf48a23a5019007fc944 | interest in the Classical Greek heritage was complemented by a renewed emphasis on Greek Orthodox identity | 639 | null | -1 | false |
Buddhism | Following (or leading up to) the schisms, each Saṅgha started to accumulate an Abhidharma, a detailed scholastic reworking of doctrinal material appearing in the Suttas, according to schematic classifications. These Abhidharma texts do not contain systematic philosophical treatises, but summaries or numerical lists. Scholars generally date these texts to around the 3rd century BCE, 100 to 200 years after the death of the Buddha. Therefore the seven Abhidharma works are generally claimed not to represent the words of the Buddha himself, but those of disciples and great scholars.[note 38] Every school had its own version of the Abhidharma, with different theories and different texts. The different Abhidharmas of the various schools did not agree with each other. Scholars disagree on whether the Mahasanghika school had an Abhidhamma Pitaka or not.[note 38] | There is a disagreement on whether a school had an Abhidhamma or not, which school is it? | 56d26abd59d6e41400145fa5 | Mahasanghika | 804 | null | -1 | false |
Dell | Dell's manufacturing process covers assembly, software installation, functional testing (including "burn-in"), and quality control. Throughout most of the company's history, Dell manufactured desktop machines in-house and contracted out manufacturing of base notebooks for configuration in-house. The company's approach has changed, as cited in the 2006 Annual Report, which states, "We are continuing to expand our use of original design manufacturing partnerships and manufacturing outsourcing relationships." The Wall Street Journal reported in September 2008 that "Dell has approached contract computer manufacturers with offers to sell" their plants. By the late 2000s, Dell's "configure to order" approach of manufacturing—delivering individual PCs configured to customer specifications from its US facilities was no longer as efficient or competitive with high-volume Asian contract manufacturers as PCs became powerful low-cost commodities. | Which of Dell's processes handles PC assembly, testing, and quality control? | 570fc88e80d9841400ab367d | manufacturing | 7 | null | -1 | false |
Republic_of_the_Congo | Congo-Brazzaville has had a multi-party political system since the early 1990s, although the system is heavily dominated by President Denis Sassou Nguesso; he has lacked serious competition in the presidential elections held under his rule. Sassou Nguesso is backed by his own Congolese Labour Party (French: Parti Congolais du Travail) as well as a range of smaller parties. | Which party does Sassou belong to? | 56dcf8b79a695914005b94a7 | Congolese Labour Party | 277 | null | -1 | false |
Arena_Football_League | The year 2000 brought heightened interest in the AFL. Then-St. Louis Rams quarterback Kurt Warner, who was MVP of Super Bowl XXXIV, was first noticed because he played quarterback for the AFL's Iowa Barnstormers. While many sports commentators and fans continued to ridicule the league, Warner's story gave the league positive exposure, and it brought the league a new television deal with TNN, which, unlike ESPN, televised regular season games live. While it was not financially lucrative, it helped set the stage for what the league would become in the new millennium. Also, the year also brought a spin-off league, the AF2, intended to be a developmental league, comparable to the National Football League's NFL Europe. There was a lot of expansion in the 2000s. Expansion teams included the Austin Wranglers, Carolina Cobras, Los Angeles Avengers, Chicago Rush, Detroit Fury, Dallas Desperados, Colorado Crush, New Orleans VooDoo, Philadelphia Soul, Nashville Kats, Kansas City Brigade, New York Dragons and Utah Blaze. Some of these teams, including the Crush, Desperados, Kats, and VooDoo, were owned by the same group which owned the NFL teams in their host cities. The NFL purchased, but never exercised, an option to buy a major interest the AFL. Of all of these teams, only the Soul still compete in the AFL as of now. | Kurt Warner was the Most Valuable Player in what Super Bowl? | 56e79cbc37bdd419002c422c | Super Bowl XXXIV | 114 | null | -1 | false |
Houston | The Houston area has over 150 active faults (estimated to be 300 active faults) with an aggregate length of up to 310 miles (500 km), including the Long Point–Eureka Heights fault system which runs through the center of the city. There have been no significant historically recorded earthquakes in Houston, but researchers do not discount the possibility of such quakes having occurred in the deeper past, nor occurring in the future. Land in some areas southeast of Houston is sinking because water has been pumped out of the ground for many years. It may be associated with slip along the faults; however, the slippage is slow and not considered an earthquake, where stationary faults must slip suddenly enough to create seismic waves. These faults also tend to move at a smooth rate in what is termed "fault creep", which further reduces the risk of an earthquake. | What is the total width of the Houston faults? | 5ad41e54604f3c001a400638 | null | -1 | 310 miles | 114 | true |
The_Sun_(United_Kingdom) | The main party leaders, David Cameron, Nick Clegg and Ed Miliband, were all depicted holding a copy of the special issue in publicity material. Miliband's decision to pose with a copy of The Sun received a strong response. Organisations representing the relatives of Hillsborough victims described Miliband's action as an "absolute disgrace" and he faced criticism too from Liverpool Labour MPs and the city's Labour Mayor, Joe Anderson. A statement was issued on 13 June explaining that Miliband "was promoting England's bid to win the World Cup", although "he understands the anger that is felt towards the Sun over Hillsborough by many people in Merseyside and he is sorry to those who feel offended." | What emotion did many people feel over The Sun's coverage of Hillsborough? | 5726b718708984140094cec3 | anger | 578 | null | -1 | false |
Muammar_Gaddafi | In 1977, Gaddafi dissolved the Republic and created a new socialist state, the Jamahiriya ("state of the masses"). Officially adopting a symbolic role in governance, he retained power as military commander-in-chief and head of the Revolutionary Committees responsible for policing and suppressing opponents. Overseeing unsuccessful border conflicts with Egypt and Chad, Gaddafi's support for foreign militants and alleged responsibility for the Lockerbie bombing led to Libya's label of "international pariah". A particularly hostile relationship developed with the United States and United Kingdom, resulting in the 1986 U.S. bombing of Libya and United Nations-imposed economic sanctions. Rejecting his earlier ideological commitments, from 1999 Gaddafi encouraged economic privatization and sought rapprochement with Western nations, also embracing Pan-Africanism and helping to establish the African Union. Amid the Arab Spring, in 2011 an anti-Gaddafist uprising led by the National Transitional Council (NTC) broke out, resulting in the Libyan Civil War. NATO intervened militarily on the side of the NTC, bringing about the government's downfall. Retreating to Sirte, Gaddafi was captured and killed by NTC militants. | How did Gaddafi lose power? | 572eb943c246551400ce4577 | an anti-Gaddafist uprising led by the National Transitional Council (NTC) broke out, resulting in the Libyan Civil War | 941 | null | -1 | false |
Time | Immanuel Kant, in the Critique of Pure Reason, described time as an a priori intuition that allows us (together with the other a priori intuition, space) to comprehend sense experience. With Kant, neither space nor time are conceived as substances, but rather both are elements of a systematic mental framework that necessarily structures the experiences of any rational agent, or observing subject. Kant thought of time as a fundamental part of an abstract conceptual framework, together with space and number, within which we sequence events, quantify their duration, and compare the motions of objects. In this view, time does not refer to any kind of entity that "flows," that objects "move through," or that is a "container" for events. Spatial measurements are used to quantify the extent of and distances between objects, and temporal measurements are used to quantify the durations of and between events. Time was designated by Kant as the purest possible schema of a pure concept or category. | What does the mind allow us to do according to Immanuel Kant? | 5a7e003d70df9f001a8753fe | null | -1 | to comprehend sense experience | 154 | true |
General_Electric | GE is a multinational conglomerate headquartered in Fairfield, Connecticut. Its main offices are located at 30 Rockefeller Plaza at Rockefeller Center in New York City, known now as the Comcast Building. It was formerly known as the GE Building for the prominent GE logo on the roof; NBC's headquarters and main studios are also located in the building. Through its RCA subsidiary, it has been associated with the center since its construction in the 1930s. GE moved its corporate headquarters from the GE Building on Lexington Avenue to Fairfield in 1974. | In what year was GE incorporated? | 59d288272763a60018284078 | null | -1 | 1974 | 551 | true |
Bacteria | Bacteria exhibit an extremely wide variety of metabolic types. The distribution of metabolic traits within a group of bacteria has traditionally been used to define their taxonomy, but these traits often do not correspond with modern genetic classifications. Bacterial metabolism is classified into nutritional groups on the basis of three major criteria: the kind of energy used for growth, the source of carbon, and the electron donors used for growth. An additional criterion of respiratory microorganisms are the electron acceptors used for aerobic or anaerobic respiration. | What is commonly used to determine taxonomy of bacteria? | 572fb921947a6a140053cbde | The distribution of metabolic traits | 63 | null | -1 | false |
Bird | Many birds show plumage patterns in ultraviolet that are invisible to the human eye; some birds whose sexes appear similar to the naked eye are distinguished by the presence of ultraviolet reflective patches on their feathers. Male blue tits have an ultraviolet reflective crown patch which is displayed in courtship by posturing and raising of their nape feathers. Ultraviolet light is also used in foraging—kestrels have been shown to search for prey by detecting the UV reflective urine trail marks left on the ground by rodents. The eyelids of a bird are not used in blinking. Instead the eye is lubricated by the nictitating membrane, a third eyelid that moves horizontally. The nictitating membrane also covers the eye and acts as a contact lens in many aquatic birds. The bird retina has a fan shaped blood supply system called the pecten. Most birds cannot move their eyes, although there are exceptions, such as the great cormorant. Birds with eyes on the sides of their heads have a wide visual field, while birds with eyes on the front of their heads, such as owls, have binocular vision and can estimate the depth of field. The avian ear lacks external pinnae but is covered by feathers, although in some birds, such as the Asio, Bubo and Otus owls, these feathers form tufts which resemble ears. The inner ear has a cochlea, but it is not spiral as in mammals. | What is the fan shaped blood supply system in a bird's retina? | 573125a9e6313a140071cc87 | pecten | 839 | null | -1 | false |
Mary_(mother_of_Jesus) | Mary had been venerated since Early Christianity, and is considered by millions to be the most meritorious saint of the religion. The Eastern and Oriental Orthodox, Roman Catholic, Anglican, and Lutheran Churches believe that Mary, as Mother of Jesus, is the Mother of God and the Theotokos, literally "Giver of birth to God". There is significant diversity in the Marian beliefs and devotional practices of major Christian traditions. The Roman Catholic Church holds distinctive Marian dogmas; namely her status as the mother of God; her Immaculate Conception; her perpetual virginity; and her Assumption into heaven. Many Protestants minimize Mary's role within Christianity, based on the argued brevity of biblical references. Mary (Maryam) also has a revered position in Islam, where a whole chapter of the Qur'an is devoted to her, also describing the birth of Jesus. | What is Mary called in Islam? | 570cdc1afed7b91900d45a37 | Maryam | 736 | null | -1 | false |
Gramophone_record | Electric recording which developed during the time that early radio was becoming popular (1925) benefited from the microphones and amplifiers used in radio studios. The early electric recordings were reminiscent tonally of acoustic recordings, except there was more recorded bass and treble as well as delicate sounds and overtones cut on the records. This was in spite of some carbon microphones used, which had resonances that colored the recorded tone. The double button carbon microphone with stretched diaphragm was a marked improvement. Alternatively, the Wente style condenser microphone used with the Western Electric licensed recording method had a brilliant midrange and was prone to overloading from sibilants in speech, but generally it gave more accurate reproduction than carbon microphones. | What was a benefit of early radio recordings? | 5727f56fff5b5019007d9942 | microphones and amplifiers | 115 | null | -1 | false |
Railway_electrification_system | An early advantage of AC is that the power-wasting resistors used in DC locomotives for speed control were not needed in an AC locomotive: multiple taps on the transformer can supply a range of voltages. Separate low-voltage transformer windings supply lighting and the motors driving auxiliary machinery. More recently, the development of very high power semiconductors has caused the classic "universal" AC/DC motor to be largely replaced with the three-phase induction motor fed by a variable frequency drive, a special inverter that varies both frequency and voltage to control motor speed. These drives can run equally well on DC or AC of any frequency, and many modern electric locomotives are designed to handle different supply voltages and frequencies to simplify cross-border operation. | No modern electric locomotives are designed to handle what? | 5acd7ee207355d001abf4479 | null | -1 | different supply voltages and frequencies | 719 | true |
Molotov%E2%80%93Ribbentrop_Pact | By the end of May, drafts were formally presented. In mid-June, the main Tripartite negotiations started. The discussion was focused on potential guarantees to central and east European countries should a German aggression arise. The USSR proposed to consider that a political turn towards Germany by the Baltic states would constitute an "indirect aggression" towards the Soviet Union. Britain opposed such proposals, because they feared the Soviets' proposed language could justify a Soviet intervention in Finland and the Baltic states, or push those countries to seek closer relations with Germany. The discussion about a definition of "indirect aggression" became one of the sticking points between the parties, and by mid-July, the tripartite political negotiations effectively stalled, while the parties agreed to start negotiations on a military agreement, which the Soviets insisted must be entered into simultaneously with any political agreement. | What month didn't the Tripartite discussions begin between Britain, USSR and France? | 5ad27de2d7d075001a4296da | null | -1 | mid-June | 54 | true |
Political_philosophy | Islamic political philosophy, was, indeed, rooted in the very sources of Islam—i.e., the Qur'an and the Sunnah, the words and practices of Muhammad—thus making it essentially theocratic. However, in the Western thought, it is generally supposed that it was a specific area peculiar merely to the great philosophers of Islam: al-Kindi (Alkindus), al-Farabi (Abunaser), İbn Sina (Avicenna), Ibn Bajjah (Avempace), Ibn Rushd (Averroes), and Ibn Khaldun. The political conceptions of Islam such as kudrah (power), sultan, ummah, cemaa (obligation)-and even the "core" terms of the Qur'an—i.e., ibadah (worship), din (religion), rab (master) and ilah (deity)—is taken as the basis of an analysis. Hence, not only the ideas of the Muslim political philosophers but also many other jurists and ulama posed political ideas and theories. For example, the ideas of the Khawarij in the very early years of Islamic history on Khilafa and Ummah, or that of Shia Islam on the concept of Imamah are considered proofs of political thought. The clashes between the Ehl-i Sunna and Shia in the 7th and 8th centuries had a genuine political character. | How did the ilah generally suppose Islamic philosophy was rooted? | 5a21b2758a6e4f001aa08e70 | null | -1 | it was a specific area peculiar merely to the great philosophers of Islam | 250 | true |
Federalism | The structures of most federal governments incorporate mechanisms to protect the rights of component states. One method, known as 'intrastate federalism', is to directly represent the governments of component states in federal political institutions. Where a federation has a bicameral legislature the upper house is often used to represent the component states while the lower house represents the people of the nation as a whole. A federal upper house may be based on a special scheme of apportionment, as is the case in the senates of the United States and Australia, where each state is represented by an equal number of senators irrespective of the size of its population. | What is intrastate federalism? | 5728402c4b864d19001647fa | is to directly represent the governments of component states in federal political institutions | 155 | null | -1 | false |
Germans | After Christianization, the Roman Catholic Church and local rulers led German expansion and settlement in areas inhabited by Slavs and Balts, known as Ostsiedlung. During the wars waged in the Baltic by the Catholic German Teutonic Knights; the lands inhabited by the ethnic group of the Old Prussians (the current reference to the people known then simply as the "Prussians"), were conquered by the Germans. The Old Prussians were an ethnic group related to the Latvian and Lithuanian Baltic peoples. The former German state of Prussia took its name from the Baltic Prussians, although it was led by Germans who had assimilated the Old Prussians; the old Prussian language was extinct by the 17th or early 18th century. The Slavic people of the Teutonic-controlled Baltic were assimilated into German culture and eventually there were many intermarriages of Slavic and German families, including amongst the Prussia's aristocracy known as the Junkers. Prussian military strategist Karl von Clausewitz is a famous German whose surname is of Slavic origin. Massive German settlement led to the assimilation of Baltic (Old Prussians) and Slavic (Wends) populations, who were exhausted by previous warfare. | When was the Prussian language extinct? | 57293a886aef051400154b9e | 17th or early 18th century | 693 | null | -1 | false |
Oklahoma | In the 2007–2008 school year, there were 181,973 undergraduate students, 20,014 graduate students, and 4,395 first-professional degree students enrolled in Oklahoma colleges. Of these students, 18,892 received a bachelor's degree, 5,386 received a master's degree, and 462 received a first professional degree. This means the state of Oklahoma produces an average of 38,278 degree-holders per completions component (i.e. July 1, 2007 – June 30, 2008). National average is 68,322 total degrees awarded per completions component. | How many grad students were in Oklahoma in 2007? | 5727e0cc2ca10214002d9899 | 20,014 | 73 | null | -1 | false |
Heresy | In certain historical Christian, Islamic and Jewish cultures, among others, espousing ideas deemed heretical has been and in some cases still is subjected not merely to punishments such as excommunication, but even to the death penalty. | What cultures are listed as examples of discipline for being a heretic? | 56de6fea4396321400ee28c9 | Christian, Islamic and Jewish | 22 | null | -1 | false |
Textual_criticism | Shemaryahu Talmon, who summarized the amount of consensus and genetic relation to the Urtext of the Hebrew Bible, concluded that major divergences which intrinsically affect the sense are extremely rare. As far as the Hebrew Bible referenced by Old Testament is concerned, almost all of the textual variants are fairly insignificant and hardly affect any doctrine. Professor Douglas Stuart states: "It is fair to say that the verses, chapters, and books of the Bible would read largely the same, and would leave the same impression with the reader, even if one adopted virtually every possible alternative reading to those now serving as the basis for current English translations." | How common are variations in text that alter the meaning of the Urtext of the Hebrew Bible? | 5727a7474b864d1900163988 | extremely rare | 188 | null | -1 | false |
Gramophone_record | The "orange peel" effect on vinyl records is caused by worn molds. Rather than having the proper mirror-like finish, the surface of the record will have a texture that looks like orange peel. This introduces noise into the record, particularly in the lower frequency range. With direct metal mastering (DMM), the master disc is cut on a copper-coated disc, which can also have a minor "orange peel" effect on the disc itself. As this "orange peel" originates in the master rather than being introduced in the pressing stage, there is no ill effect as there is no physical distortion of the groove. | On what frequencies is an orange peel effect most noticeable? | 5727e0dbff5b5019007d9761 | lower frequency range | 251 | null | -1 | false |
FC_Barcelona | In late December, Barcelona's appeal to the Court of Arbitration for Sport was unsuccessful and the original transfer ban was reinstated, leaving the club unable to utilise the 2015 winter and summer transfer windows. On 5 January 2015, Zubizareta was sacked by the board after 4 years as director of football. The next month, Barcelona announced the formation of a new Football Area Technical Commission, made up of vice-president Jordi Mestre, board member Javier Bordas, Carles Rexach and Ariedo Braida. | To whom did Barcelona appeal to lift the transfer bad? | 570c3666ec8fbc190045bdc8 | Court of Arbitration for Sport | 44 | null | -1 | false |
Presbyterianism | The Presbyterian Church in Vanuatu is the largest denomination in the country, with approximately one-third of the population of Vanuatu members of the church. The PCV was taken to Vanuatu by missionaries from Scotland. The PCV (Presbyterian Church of Vanuatu) is headed by a moderator with offices in Port Vila. The PCV is particularly strong in the provinces of Tafea, Shefa, and Malampa. The Province of Sanma is mainly Presbyterian with a strong Roman Catholic minority in the Francophone areas of the province. There are some Presbyterian people, but no organised Presbyterian churches in Penama and Torba, both of which are traditionally Anglican. Vanuatu is the only country in the South Pacific with a significant Presbyterian heritage and membership. The PCV is a founding member of the Vanuatu Christian Council (VCC). The PCV runs many primary schools and Onesua secondary school. The church is strong in the rural villages. | There are some organized Presbyterian churches but not Presbyterian people where? | 5acfe0e577cf76001a686388 | null | -1 | Penama and Torba | 594 | true |
Marshall_Islands | In the months before the attack on Pearl Harbor, Kwajalein Atoll was the administrative center of the Japanese 6th Fleet Forces Service, whose task was the defense of the Marshall Islands. | What was the mission of the 6th Fleet Forces Service? | 56f95bb59b226e1400dd13a4 | defense of the Marshall Islands | 156 | null | -1 | false |
High-definition_television | The optimum format for a broadcast depends upon the type of videographic recording medium used and the image's characteristics. For best fidelity to the source the transmitted field ratio, lines, and frame rate should match those of the source. | For best fidelity to the source, what three things should match the source? | 56faaa04f34c681400b0c10a | transmitted field ratio, lines, and frame rate | 164 | null | -1 | false |
Separation_of_church_and_state_in_the_United_States | The incorporation of the First Amendment establishment clause in the landmark case of Everson v. Board of Education has impacted the subsequent interpretation of the separation of church and state in regard to the state governments. Although upholding the state law in that case, which provided for public busing to private religious schools, the Supreme Court held that the First Amendment establishment clause was fully applicable to the state governments. A more recent case involving the application of this principle against the states was Board of Education of Kiryas Joel Village School District v. Grumet (1994). | When was the case of v. Grumet? | 5731bedce99e3014001e6242 | 1994 | 614 | null | -1 | false |
Egypt | Partly because of low sanitation coverage about 17,000 children die each year because of diarrhoea. Another challenge is low cost recovery due to water tariffs that are among the lowest in the world. This in turn requires government subsidies even for operating costs, a situation that has been aggravated by salary increases without tariff increases after the Arab Spring. Poor operation of facilities, such as water and wastewater treatment plants, as well as limited government accountability and transparency, are also issues. | Because of low sanitation coverage 17,000 Egyptian children to die each year from what condition? | 5731d666e17f3d1400422485 | diarrhoea | 89 | null | -1 | false |
Mesozoic | Compared to the vigorous convergent plate mountain-building of the late Paleozoic, Mesozoic tectonic deformation was comparatively mild. The sole major Mesozoic orogeny occurred in what is now the Arctic, creating the Innuitian orogeny, the Brooks Range, the Verkhoyansk and Cherskiy Ranges in Siberia, and the Khingan Mountains in Manchuria. This orogeny was related to the opening of the Arctic Ocean and subduction of the North China and Siberian cratons under the Pacific Ocean. Nevertheless, the era featured the dramatic rifting of the supercontinent Pangaea. Pangaea gradually split into a northern continent, Laurasia, and a southern continent, Gondwana. This created the passive continental margin that characterizes most of the Atlantic coastline (such as along the U.S. East Coast) today. | At what time was tectonic formation especially active? | 5a2f4e01a83784001a7d26ed | null | -1 | Mesozoic | 83 | true |
Iran | The earliest archaeological artifacts in Iran, like those excavated at the Kashafrud and Ganj Par sites, attest to a human presence in Iran since the Lower Paleolithic era, c. 800,000–200,000 BC. Iran's Neanderthal artifacts from the Middle Paleolithic period, c. 200,000–40,000 BC, have been found mainly in the Zagros region, at sites such as Warwasi and Yafteh Cave.[page needed] Around 10th to 8th millennium BC, early agricultural communities such as Chogha Golan and Chogha Bonut began to flourish in Iran, as well as Susa and Chogha Mish developing in and around the Zagros region.[page needed] | When did early agricultural communities in Iran begin to appear and prosper? | 572ff7df947a6a140053cea4 | 10th to 8th millennium BC | 390 | null | -1 | false |
Federal_Bureau_of_Investigation | FBI records show that 85% of COINTELPRO resources targeted groups and individuals that the FBI deemed "subversive", including communist and socialist organizations; organizations and individuals associated with the Civil Rights Movement, including Martin Luther King, Jr. and others associated with the Southern Christian Leadership Conference, the National Association for the Advancement of Colored People, and the Congress of Racial Equality and other civil rights organizations; black nationalist groups; the American Indian Movement; a broad range of organizations labeled "New Left", including Students for a Democratic Society and the Weathermen; almost all groups protesting the Vietnam War, as well as individual student demonstrators with no group affiliation; the National Lawyers Guild; organizations and individuals associated with the women's rights movement; nationalist groups such as those seeking independence for Puerto Rico, United Ireland, and Cuban exile movements including Orlando Bosch's Cuban Power and the Cuban Nationalist Movement. The remaining 15% of COINTELPRO resources were expended to marginalize and subvert white hate groups, including the Ku Klux Klan and the National States' Rights Party. | What is a group that the CIA targeted? | 5ad3ad33604f3c001a3febf3 | null | -1 | Southern Christian Leadership Conference | 303 | true |
Vacuum | The quality of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. Much higher-quality vacuums are possible. Ultra-high vacuum chambers, common in chemistry, physics, and engineering, operate below one trillionth (10−12) of atmospheric pressure (100 nPa), and can reach around 100 particles/cm3. Outer space is an even higher-quality vacuum, with the equivalent of just a few hydrogen atoms per cubic meter on average. According to modern understanding, even if all matter could be removed from a volume, it would still not be "empty" due to vacuum fluctuations, dark energy, transiting gamma rays, cosmic rays, neutrinos, and other phenomena in quantum physics. In the electromagnetism in the 19th century, vacuum was thought to be filled with a medium called aether. In modern particle physics, the vacuum state is considered the ground state of matter. | In what century was dark matter discovered? | 5a8771811d3cee001a6a11af | null | -1 | the 19th century | 877 | true |
Railway_electrification_system | In comparison to the principal alternative, the diesel engine, electric railways offer substantially better energy efficiency, lower emissions and lower operating costs. Electric locomotives are usually quieter, more powerful, and more responsive and reliable than diesels. They have no local emissions, an important advantage in tunnels and urban areas. Some electric traction systems provide regenerative braking that turns the train's kinetic energy back into electricity and returns it to the supply system to be used by other trains or the general utility grid. While diesel locomotives burn petroleum, electricity is generated from diverse sources including many that do not produce carbon dioxide such as nuclear power and renewable forms including hydroelectric, geothermal, wind and solar. | Electricity is generated from many sources that do produce carbon what? | 5acd6c7907355d001abf418d | null | -1 | dioxide | 696 | true |
Portugal | Continental Portugal's 89,015 km2 (34,369 sq mi) territory is serviced by four international airports located near the principal cities of Lisbon, Porto, Faro and Beja. Lisbon's geographical position makes it a stopover for many foreign airlines at several airports within the country. The primary flag-carrier is TAP Portugal, although many other domestic airlines provide services within and without the country. The government decided to build a new airport outside Lisbon, in Alcochete, to replace Lisbon Portela Airport, though this plan has been stalled due to the austerity. Currently, the most important airports are in Lisbon, Porto, Faro, Funchal (Madeira), and Ponta Delgada (Azores), managed by the national airport authority group ANA – Aeroportos de Portugal. | How many national airports does Portugal have? | 57340e1cd058e614000b68b0 | four | 74 | null | -1 | false |
New_Delhi | New Delhi has one of India's largest bus transport systems. Buses are operated by the state-owned Delhi Transport Corporation (DTC), which owns largest fleet of compressed natural gas (CNG)-fueled buses in the world. Personal vehicles especially cars also form a major chunk of vehicles plying on New Delhi roads. New Delhi has the highest number of registered cars compared to any other metropolitan city in India. Taxis and Auto Rickshaws also ply on New Delhi roads in large numbers. New Delhi has one of the highest road density in India. | What type of vehicle transport system is owned by the Delhi Transport Corporation? | 57068e4552bb891400689a5a | Buses | 60 | null | -1 | false |
The_Blitz | Communal shelters never housed more than one seventh of Greater London residents, however. Peak use of the Underground as shelter was 177,000 on 27 September 1940, and a November 1940 census of London found that about 4% of residents used the Tube and other large shelters; 9% in public surface shelters; and 27% in private home shelters, implying that the remaining 60% of the city likely stayed at home. The government distributed Anderson shelters until 1941 and that year began distributing the Morrison shelter, which could be used inside homes.:190 | Where could the Morrison shelters be used? | 572fabd004bcaa1900d76bad | inside homes | 537 | null | -1 | false |
Multiracial_American | Many Latin American migrants have been mestizo, Amerindian, or other mixed race. Multiracial Latinos have limited media appearance; critics have accused the U.S. Hispanic media of overlooking the brown-skinned indigenous and multiracial Hispanic and black Hispanic populations by over-representation of blond and blue/green-eyed white Hispanic and Latino Americans (who resemble Scandinavians and other Northern Europeans rather than they look like white Hispanic and Latino Americans mostly of typical Southern European features), and also light-skinned mulatto and mestizo Hispanic and Latino Americans (often deemed as white persons in U.S. Hispanic and Latino populations if achieving the middle class or higher social status), especially some of the actors on the telenovelas. | What are many Latin American migrants? | 571dfdc5b64a571400c71e4a | mestizo, Amerindian, or other mixed race | 39 | null | -1 | false |
Post-punk | In the mid 1970s, various American groups (some with ties to Downtown Manhattan's punk scene, including Television and Suicide) had begun expanding on the vocabulary of punk music. Midwestern groups such as Pere Ubu and Devo drew inspiration from the region's derelict industrial environments, employing conceptual art techniques, musique concrète and unconventional verbal styles that would presage the post-punk movement by several years. A variety of subsequent groups, including New York-based Talking Heads and Boston-based Mission of Burma, combined elements of punk with art school sensibilities. In 1978, the former band began a series of collaborations with British ambient pioneer and ex-Roxy Music member Brian Eno, experimenting with Dada-influenced lyrical techniques, dance music, and African polyrhythms. San Francisco's vibrant post-punk scene was centered around such groups as Chrome, the Residents and Tuxedomoon, who incorporated multimedia experimentation, film and ideas from Antonin Artaud's Theater of Cruelty. | What groups were not interested in the punk scene? | 5a284f28d1a287001a6d0b42 | null | -1 | American | 26 | true |
Transistor | Bipolar transistors are so named because they conduct by using both majority and minority carriers. The bipolar junction transistor, the first type of transistor to be mass-produced, is a combination of two junction diodes, and is formed of either a thin layer of p-type semiconductor sandwiched between two n-type semiconductors (an n–p–n transistor), or a thin layer of n-type semiconductor sandwiched between two p-type semiconductors (a p–n–p transistor). This construction produces two p–n junctions: a base–emitter junction and a base–collector junction, separated by a thin region of semiconductor known as the base region (two junction diodes wired together without sharing an intervening semiconducting region will not make a transistor). | What kind of transistor is used the most? | 5a7b775521c2de001afea042 | null | -1 | Bipolar transistors | 0 | true |
Germans | The Nazis, led by Adolf Hitler, attempted to unite all the people they claimed were "Germans" (Volksdeutsche) into one realm, including ethnic Germans in eastern Europe, many of whom had emigrated more than one hundred fifty years before and developed separate cultures in their new lands. This idea was initially welcomed by many ethnic Germans in Sudetenland, Austria, Poland, Danzig and western Lithuania, particularly the Germans from Klaipeda (Memel). The Swiss resisted the idea. They had viewed themselves as a distinctly separate nation since the Peace of Westphalia of 1648. | When was the Peace of Westphalia? | 5729508d3f37b31900478236 | 1648 | 578 | null | -1 | false |
Hyderabad | Hyderabad emerged as the foremost centre of culture in India with the decline of the Mughal Empire. After the fall of Delhi in 1857, the migration of performing artists to the city particularly from the north and west of the Indian sub continent, under the patronage of the Nizam, enriched the cultural milieu. This migration resulted in a mingling of North and South Indian languages, cultures and religions, which has since led to a co-existence of Hindu and Muslim traditions, for which the city has become noted.:viii A further consequence of this north–south mix is that both Telugu and Urdu are official languages of Telangana. The mixing of religions has also resulted in many festivals being celebrated in Hyderabad such as Ganesh Chaturthi, Diwali and Bonalu of Hindu tradition and Eid ul-Fitr and Eid al-Adha by Muslims. | The festival of Diwali is a tradition of what faith? | 572f9c93b2c2fd140056824f | Hindu | 771 | null | -1 | false |
Pharmaceutical_industry | In 1937 over 100 people died after ingesting "Elixir Sulfanilamide" manufactured by S.E. Massengill Company of Tennessee. The product was formulated in diethylene glycol, a highly toxic solvent that is now widely used as antifreeze. Under the laws extant at that time, prosecution of the manufacturer was possible only under the technicality that the product had been called an "elixir", which literally implied a solution in ethanol. In response to this episode, the U.S. Congress passed the Federal Food, Drug, and Cosmetic Act of 1938, which for the first time required pre-market demonstration of safety before a drug could be sold, and explicitly prohibited false therapeutic claims. | What is Diethylene Glycol commonly used for now? | 571aaeda10f8ca14003052d8 | antifreeze | 221 | null | -1 | false |
Oklahoma | In descending order of population, Oklahoma's largest cities in 2010 were: Oklahoma City (579,999, +14.6%), Tulsa (391,906, −0.3%), Norman (110,925, +15.9%), Broken Arrow (98,850, +32.0%), Lawton (96,867, +4.4%), Edmond (81,405, +19.2%), Moore (55,081, +33.9%), Midwest City (54,371, +0.5%), Enid (49,379, +5.0%), and Stillwater (45,688, +17.0%). Of the state's ten largest cities, three are outside the metropolitan areas of Oklahoma City and Tulsa, and only Lawton has a metropolitan statistical area of its own as designated by the United States Census Bureau, though the metropolitan statistical area of Fort Smith, Arkansas extends into the state. | How many people lived in Lawton in 2010? | 5727e7d44b864d1900163fb8 | 96,867 | 197 | null | -1 | false |
Neptune | Neptune is similar in composition to Uranus, and both have compositions that differ from those of the larger gas giants, Jupiter and Saturn. Like Jupiter and Saturn, Neptune's atmosphere is composed primarily of hydrogen and helium, along with traces of hydrocarbons and possibly nitrogen, but contains a higher proportion of "ices" such as water, ammonia, and methane. However, its interior, like that of Uranus, is primarily composed of ices and rock, and hence Uranus and Neptune are normally considered "ice giants" to emphasise this distinction. Traces of methane in the outermost regions in part account for the planet's blue appearance. | what color does helium make neptune? | 5ace970b32bba1001ae4ab57 | null | -1 | blue | 627 | true |
Unicode | Unicode can be implemented by different character encodings. The most commonly used encodings are UTF-8, UTF-16 and the now-obsolete UCS-2. UTF-8 uses one byte for any ASCII character, all of which have the same code values in both UTF-8 and ASCII encoding, and up to four bytes for other characters. UCS-2 uses a 16-bit code unit (two 8-bit bytes) for each character but cannot encode every character in the current Unicode standard. UTF-16 extends UCS-2, using one 16-bit unit for the characters that were representable in UCS-2 and two 16-bit units (4 × 8 bits) to handle each of the additional characters. | What system has a minimum of four bytes? | 5acd0ee707355d001abf32bc | null | -1 | UTF-8 | 140 | true |
Red | So that the maximum number of colors can be accurately reproduced on your computer screen, each color has been given a code number, or sRGB, which tells your computer the intensity of the red, green and blue components of that color. The intensity of each component is measured on a scale of zero to 255, which means the complete list includes 16,777,216 distinct colors and shades. The sRGB number of pure red, for example, is 255, 00, 00, which means the red component is at its maximum intensity, and there is no green or blue. The sRGB number for crimson is 220, 20, 60, which means that the red is slightly less intense and therefore darker, there is some green, which leans it toward orange; and there is a larger amount of blue,which makes it slightly blue-violet. | What is an sRBG? | 5ad4e4705b96ef001a10a57c | null | -1 | a code number | 117 | true |
Central_Intelligence_Agency | The success of the British Commandos during World War II prompted U.S. President Franklin D. Roosevelt to authorize the creation of an intelligence service modeled after the British Secret Intelligence Service (MI6), and Special Operations Executive. This led to the creation of the Office of Strategic Services (OSS). On September 20, 1945, shortly after the end of World War II, Harry S. Truman signed an executive order dissolving the OSS, and by October 1945 its functions had been divided between the Departments of State and War. The division lasted only a few months. The first public mention of the "Central Intelligence Agency" appeared on a command-restructuring proposal presented by Jim Forrestal and Arthur Radford to the U.S. Senate Military Affairs Committee at the end of 1945. Despite opposition from the military establishment, the United States Department of State and the Federal Bureau of Investigation (FBI), Truman established the National Intelligence Authority in January 1946, which was the direct predecessor of the CIA. Its operational extension was known as the Central Intelligence Group (CIG) | Who signed the order to get rid of the OSS? | 572f5607b2c2fd1400568038 | Harry S. Truman | 381 | null | -1 | false |
United_States_Army | By the twentieth century, the U.S. Army had mobilized the U.S. Volunteers on four separate occasions during each of the major wars of the nineteenth century. During World War I, the "National Army" was organized to fight the conflict, replacing the concept of U.S. Volunteers. It was demobilized at the end of World War I, and was replaced by the Regular Army, the Organized Reserve Corps, and the State Militias. In the 1920s and 1930s, the "career" soldiers were known as the "Regular Army" with the "Enlisted Reserve Corps" and "Officer Reserve Corps" augmented to fill vacancies when needed. | When was the National Army demobilized? | 570d2b46b3d812140066d4dc | end of World War I | 303 | null | -1 | false |
Endangered_Species_Act | The provision of the law in Section 4 that establishes critical habitat is a regulatory link between habitat protection and recovery goals, requiring the identification and protection of all lands, water and air necessary to recover endangered species. To determine what exactly is critical habitat, the needs of open space for individual and population growth, food, water, light or other nutritional requirements, breeding sites, seed germination and dispersal needs, and lack of disturbances are considered. | What type of link is formed between identification and protection? | 5a8462357cf838001a46a7c7 | null | -1 | regulatory | 77 | true |
Dutch_language | Voicing of pre-vocalic initial voiceless alveolar fricatives occurs, although less in Dutch than in German (Du zeven, Germ sieben [z] vs. Eng seven and LG seven [s]), and also the shift in /θ/ > /d/. Dutch shares only with Low German the development of /xs/ > /ss/ (Du vossen, ossen and LG Vösse, Ossen vs. Germ Füchse, Ochsen and Eng foxes, oxen), and also the development of /ft/ → /xt/ though it is far more common in Dutch (Du zacht and LG sacht vs. Germ sanft and Eng soft, but Du kracht vs. LG/Germ kraft and Eng cognate craft). | Is the voicing of pre-vocalic initial voiceless alveolar fricatives more common in Dutch or German? | 5726783af1498d1400e8e0c8 | German | 100 | null | -1 | false |
