I'm taking a test and have to guess the right answer to the question after the article. Article: Astronomers have captured  the first direct image of a planet being born. Adam Kraus, of the University of Hawaii's Institute for Astronomy, said the planet is being formed out of dust and gas circling a 2-million-yea-old star about 450 light years from Earth. The planet itself, based on scientific models of how planets form, is believed to have started taking shape about 50,000 to 100,000 years ago. Called LkCa 15b, it's the youngest planet ever observed. The previous record holder was about five times older. Kraus and his colleague, Michael Ireland from Macquarie University and the Australian Astronomical Observatory, used Keck telescopes on Mauna Kea(a volcano on the island of Hawaii, US) to find the planet. Kraus presented the discovery Wednesday at NASA's Goddard Space Flight Center in Maryland. Observing planets while they're forming can help scientists answer questions like weather planets form early in the life of a star or later, and whether they form relatively close to stars or father away. Planets can change orbits  after forming, so it's difficult to answer such questions by studying older planets. "These very basic questions of when and where are best answered when you can actually see the planet forming, as the process is happening right now," Kraus said. Scientists hadn't been able to see such young planets before because the stars they're circling around outshine  them. Kraus and Ireland used two techniques to overcome this problem.[:++] One method, which is also used by other astronomers, was to change the shape of the telescope mirrors to remove light distortion  created by the Earth's atmosphere. The other method they used, which was unique, was to put masks with several holes over most of the telescope mirrors. The combination of these techniques allowed the astronomers to obtain high-quality images that let them see the planet next to the bright star. The star LkCa 15--the planet is named after its star--was the team's second target. They immediately knew they were seeing something new,... Question: Which of the following would be the best title for the text? Options: A: Youngest planet seen as it's forming. B: Planet 450 light years away discovered. C: World's first direct image of a planet taken. D: New technique helps discover young planets.

I'm taking a test and have to guess the right answer to the question after the article. Article: I have nothing to say about whether or not "A Day Without Immigrants " had a positive or negative effect on the question of how the federal government should deal with the huge population of undocumented illegal immigrants in this country. I'll leave that question to others. Regardless of how you feel about the event, one conclusion is obvious. Using the theme of "A Day Without" as a way to focus national attention on a particular subject is a great idea, and could serve as a method for increasing public consciousness about other issues that affect daily life in America. Here are my top three examples: "A Day Without Speeding." How hard could this be? If all drivers would strictly obey every posted speed limit on highways, downtown, on neighborhood streets, and in parking lots for one 24-hour cycle, the benefits would be huge. "A Day Without Losing Your Temper." A higher degree of difficulty here, and I know that from personal experience. When something goes wrong at home or on the job, there may be brief satisfaction in yelling or kicking the furniture, but bursting into anger usually has nothing to do with the approach to the heart of the matter. "A Day Without Having All The Answers." I would like to get a break from hearing anyone speak the phrase, "Here's what you're doing wrong." Right now the US is packed with citizens who believe they can point out the cause of every single problem in existence and then solve it in a moment. I believe they need to be quiet sometimes and use their ears instead of their voices. I wonder how would average Americans react to such a national pause? Would it be a day of reaction against anger, or joyful celebrations? Question: According to the author, losing one's temper is   _  . Options: A: unpleasant B: pointless C: relaxing D: personal
B

I'm taking a test and have to guess the right answer to the question after the article. Article: American women experience a great variety of lifestyle. A typical American woman may be single. She may also be divorced or married. She may be a homemaker, a doctor or a factory worker. It is very difficult to generalize about American women. However, one thing that many American women have in common is their attitudes about themselves and their roles in American life. Historically, American women have always been very independent. The first settlers to come to New England were ten young couples that had left behind their extended families. The women were alone in a new, undeveloped country with their husbands. This has two important effects. First of all, this was the uncivilized environment that demanded every person to share in developing it and in survival. Women worked with their husbands and children to make themselves accepted in this new land. Second, because they were in a new land without the established influence of older members of society, women felt free to step into non--traditional roles. This role of women was strengthened in later years as Americans move west again, leaving families behind and meeting a new environment. Even later, in the east, as new settlers arrived, women often found jobs more easily than men. Women became the supporters of the family. Within the established lifestyle of the industrialized twentieth century, the strong role of women was not attractive as in the early days of the country. Some women stepped into the men's jobs as factory and business workers. After the war, some women stayed in these positions, and others left their jobs with a new sense of ability. Question: Women took part in men's job during the time of  _  . Options: A: the Second World War B: the Westward Movement C: the early immigration D: the industrialized twentieth century.

I'm taking a test and have to guess the right answer to the question after the article. Article: Using a computer or smartphone at night can cause us to pile on the pounds,new research has revealed. The study found a link between blue light exposure(blue light is produced by smartphones and computers)and increased hunger.It found that exposure to blue light increases hunger levels for several hours and even increases hunger levels after eating a meal.Blue light exposure has also already been shown to cause decreased  sleepiness in the evening,increasing the risk of sleeplessness. The leading researcher,Ivy Cheung,from Northwestern University in Chicago,said,"A single three-hour exposure to blue-enriched light in the evening greatly affected hunger and metabolism .These results are important because they suggest that controlling environmental light exposure for humans may represent a _ approach of influencing food intake patterns and metabolism." The study group consisted of 10 healthy adults with regular sleep and eating schedules. They completed a four-day trial under dim light conditions,which involved exposure to less than 20 lux(,)during 16 hours awake and less than 3 lux during eight hours of sleep.On the third day they were exposed to three hours of 260 lux,blue-enriched light starting10.5 hours after waking up.and the effects were compared with dim light exposure. Ivy Cheung said more research is needed to determine the functions involved in the relationship between light exposure,hunger and metabolism. Question: What can we learn from the passage? Options: A: Blue light exposure can make us lose weight at night. B: Blue light exposure has no effect on sleeplessness. C: The researchers drew their conclusion by comparison. D: Ivy Cheung has found the relationship between light exposure and hunger.
