Read the following article and select the best answer. Article: Enough "meaningless drivel". That's the message from a group of members of the UK government who have been examining how social media firms like LinkedIn gather and use social media data. The House of Commons Science and Technology Committee's report, released last week, has blamed firms for making people sign up to long incomprehensible legal contracts and calls for an international standard or kitemark   to identify sites that have clear terms and conditions. "The term and conditions statement that we all carelessly agree to is meaningless drivel to anyone," says Andrew Miller, the chair of the committee. Instead, he says, firms should provide a plain-English version of their terms. The simplified version would be checked by a third party and awarded a kitemark if it is an accurate reflection of the original. It is not yet clear who would administer the scheme, but the UK government is looking at introducing it on a voluntary basis. "we need to think through how we make that work in practice," says Miller. Would we pay any more attention to a kitemark? "I think if you went and did the survey, people would like to think they would," says Nigel Shadbolt at the University of Southampton, UK, who studies open data. "We do know people worry a lot about the inappropriate use of their information." But what would happen in practice is another matter, he says. Other organisations such as banks ask customers to sign long contracts they may not read or understand, but Miller believes social media requires special attention because it is so new. "We still don't know how significant the long-term impact is going to be of unwise things that kids put on social media that come back and bite them in 20 years' time," he says. Shadbolt, who gave evidence to the committee, says the problem is that we don't know how companies will use our data because their business models and uses of data are still evolving. Large collections of personal information have become valuable only recently, he says. The shock and anger when a... Question: Andrew Miller thinks social media needs more attention than banks mainly because   _  . - their users consist largely of kids under 20 years old - the language in their contracts is usually harder to understand - the information they collected could become more valuable in future - it remains unknown how users' data will be taken advantage of
it remains unknown how users' data will be taken advantage of

Read the following article and select the best answer. Article: Scholars and researchers have tried to discover what personality characteristics go along with success in intercultural experiences. Their findings have often been unclear or incomplete. But three characteristics stand out in their reports: patience, a sense of humor, and the awareness of being unclear. Patience, of course, is the ability to keep calm even when things do not go as one wants them to, or hopes they will, or has even been sure they will. Impatience sometimes brings improvements in relations with other people, but usually it does not. A person with a sense of humor is less likely to take things too seriously and more ready to see the humor in her own reactions than a humorless person. The value of a sense of humor really needs to be paid more attention to. "The awareness of being unclear" is a more difficult concept than patience or a sense of humor. Foreigners often find themselves in situations that are unclear to the newcomers. That is, they do not know what is happening in the situation. Perhaps they do not understand the local language well enough, or they do not know how some system or organization works, or they can't be sure of different people's roles in what is going on. "It's like I just got here from the moon," a Chinese graduate student who newly arrived in the United States said, "things are just so different here." Question: According to the writer, the Chinese students is_. - a hard-working student - recently back from the moon - interested in the study of moon - not used to the culture in America
recently back from the moon

Read the following article and select the best answer. Article: The European Union on Monday prohibited the use of X-ray body scanners  in European airports, parting ways with the U. S. Transportation Security Administration, which has used hundreds of the scanners as a way to screen millions of airline passengers for explosives hidden under clothing. The European Commission, which enforces common policies of the EU's 27 member countries, adopted the rule "in order not to risk doing harm to citizens' health and safety." As a ProPublica/PBS NewsHour investigation detailed earlier this month, X-ray body scanners use ionizing radiation  ,a form of energy that has been shown to damage DMA and cause cancer. Although the amount of radiation is extremely low, equal to the radiation a person would receive in a few minutes of flying, several research studies have concluded that a small number of cancer cases would result from scanning hundreds of millions of passengers a year. European countries will be allowed to use an alternative body scanner relying on radio frequency waves, which have not been linked to cancer. The U. S. Transportation Security Administration (TSA) has also used hundreds of those machines --known as millimeter-wave scanners --in U. S. airports. But unlike Europe, it has decided to use both types of scanners. The TSA would not comment specifically on the EU 's decision. But in a statement, TSA spokesman Mike McCarthy said, "As one of our many layers of security, TSA uses the most advanced technology available to provide the best opportunity to detect dangerous items, such as explosives. " We strictly test our technology to ensure it meets our high detection and safety standards before it is placed in airports," he continued. "Since January 2010, advanced imaging technology has detected more than 300 dangerous or illegal items on passengers in U. S. airports nationwide." Body scanners have been controversial  in the United States since they were first used in prisons in the late 1990s and then in airports for tests after 9/11. Question: What can we infer from TSA's statement? - The TSA will stop using the X-ray scanners. - The TSA won't use EU's alternative scanners. - The EU's alternative scanners are not advanced. - The X-ray scanners are safe and effective.
The X-ray scanners are safe and effective.

Read the following article and select the best answer. Article: High-quality customer service is preached   by many, but actually keeping customers happy is easier said than done.   Shoppers seldom complain to the manager or owner of a retail store, but instead will alert their friends,  s, co-workers, strangers--and anyone who will listen.   Store managers are often the last to hear complaints, and often find out only when their regular customers decide to frequent their competitors, according to a study jointly conducted by Verde Group and Wharton School.   "Storytelling hurts retailers and entertains consumers," said Paula Courtney, President of the Verde Group. "The store loses the customer, but the shopper must also find a replacement."   On average, every unhappy customer will complain to at least four others, and will no longer visit the specific store. For every dissatisfied customer, a store will lose up to three more due to negative review. The resulting "snowball effect" can be disastrous to retailers.   According to the research, shoppers who purchased clothing encountered the most problems. Ranked second and third were grocery and electronics customers.   The most common complaints include filled parking lots, cluttered   shelves, overloaded racks, out-of-stock items, long check-out lines, and rude salespeople.   During peak shopping hours, some retailers solved parking problems by getting moonlighting   local police to work as parking attendants. Some hired flag wavers to direct customers to empty parking spaces. This guidance eliminated the need for customers to circle the parking lot endlessly, and avoided confrontation between those eyeing the same parking space.   Retailers can relieve the headaches by redesigning store layouts, pre-stocking sales items, hiring speedy and experienced cashiers, and having sales representatives on hand to answer questions.   Most importantly, salespeople should be diplomatic and polite with angry customers.   "Retailers who're responsive and friendly are more likely to smooth over issues than those who aren't so friendly,"... Question: What contributes most to smoothing over issues with customers? - Manners of the salespeople. - Hiring of efficient employees. - Huge supply of goods for sale. - Design of store layout.
