Read the following article and select the best answer. Article: US universities are among the best in the world. Since World War II, American scientists --- mostly working in universties or colleges --- have won more than half of all Nobel Prizes in physics and medicine. Foreign students rush to the United States by the tens of thousands. Last year they earned more than one quarter of the doctoral degrees awarded in the country. Yet while American universities produce the great research and great graduate program, they sometimes pay little attention to the task that lies at their very core: the teaching of undergraduate students. With the increase in fees, educators feel obliged to improve undergraduate teaching. In speeches and interviews the nation's higher educators have rediscovered teaching. Robert Rosenzweig, president of the Association of American Universities, said, "Our organization was never very concerned about teaching. In the last 18 months, we have spent more time on undergraduate education than on any other subject." Despite such promising efforts, no one doubts that research still outranks teaching at some of the leading universities, not least because it is a surer and faster way to earn status. Some people don't think it has to be that way. They argue that the reward system for college faculty can be changed, so that professors will be encouraged to devote more time and effort to teaching. They say that they are beginning to believe that the first ten years of the 21st century may come to be remembered as the decade of the undergraduate. That would bring it full circle. For more than two centuries after the founding of Harvard College in 1636, the instruction of undergraduate students was an essential condition of American higher education. Question: According to the passage, at some of the leading American universities _ . - research is declining in importance - teaching now ranks above research - teaching is a sure way to gain position - research still ranks above teaching
research still ranks above teaching

Read the following article and select the best answer. Article: If you have ever experienced jet lag ,you know how much of a drag it can be. Jet lag happens as a result of air travel, when traveling between two or more time zones. Your body is used to operating in a certain time zone, and when its timing is affected, you're likely to have problems. Edward Norton's character in the movies Fight Club faces the struggle of jet-lag-induced sleeplessness due to his constant traveling. Sleeplessness is just one of the effects of jet lag, and it can lead to other problems, such as tiredness, memory loss and confusion. That's not something you should have to fight on a business trip and it certainly won't make your vacation very enjoyable, either. Sleeplessness is the biggest problem for travelers that suffer from jet lag. Don't worry. You can do something to prevent it. Modify Your Body Clock To prevent the effects on your body's timing that come with crossing time zones, you need to change your body clock sooner, rather than later. You can do this by putting yourself on the same time as your destination time zone before you fly. If you know that you will be traveling to London from the eastern United States, you'll have a five-hour time difference to deal with. Plan for it. Avoid Heavy Food and Alcohol Part of the pleasure of flying commercially, especially if you fly business or first class, is taking advantages of the food and drinks. If you want to avoid jet lag, though, you should think twice. Eating heavy food will only make the jet lag worse. It isn't good to drink alcohol during a flight, either, because it may make you drowsy. Wait until your body adjusts before you decide to have heavy food or drink alcohol. Question: Norton's character in Fight Club has to fight with_. - confusion - sleeplessness - heavy drinking - memory loss
sleeplessness

Q: Read the following article and select the best answer. Article: Each year about a quarter of a million Americans study abroad. For many of them, a summer or a semester in a foreign country now involves more than just sitting in classrooms and hanging out with other American students. Instead, they are encouraged and sometimes required to be involved in the local communities they are studying in. "It's ly important that they know something about how people in other parts of the world live and think, and how they behave," says William Finlay, head of the sociology department at the University of Georgia. In 2008, he co-founded a study abroad program with South Africa's Stellenbosch University. It combines traditional academic in-class learning with community involvement. "We've been working with a non-government organization in the township. Our students typically either work with little children in day care centers or work in the library and teach very basic computer skills to young children," says Finlay. The three-week program proved to be an unforgettable experience for Hillary Kinsey. She says, "It was interesting to learn the history of the area and then talk to these people and see what the social dynamics were, and how certain groups felt about other groups." When Hillary Kinsey returned home from South Africa, she and other students in the program established a non-profit group. Kinsey says the group wants to contribute to advancing education and development in South Africa. "One of the purposes of the group is that we hope to raise money and awareness about the situation where those people live and help to promote any sort of educational development that we can, " Kinsey added. While many study abroad programs focus on helping Americans to learn foreign languages, others take a more intensive approach. "In all of our locations, we place students with local roommates," says Mark Lenhart, director of CEF Academic Programs, which sends more than a thousand students to China, Korea and other countries each year. He says American students benefit from such one-on-one... Question: The purposes of Hillary Kinsey's non-profit group include all of the following, EXCEPT _ . - learning more about South Africa - raising money for local people - helping to develop education in South Africa - raising people's awareness of the local situation
A: learning more about South Africa

Q: Read the following article and select the best answer. Article: If you want to avoid making impulse and unnecessary purchases,then just keep your hands away from tempting products. According to new research,individuals who touch possible items in stores are more likely to have an increased desire to purchase them than those who keep their hands off the products. Suzanne Shu and Joann Peck,marketing professors at the University of Wisconsin's business school conducted studies on the connection between touch and feelings of ownership and the effect of perceived ownership on the value placed on an object. For one of the experiments,the experts placed two products,a Slinky toy and a coffee mug in front of the volunteers who were undergraduate students. About half of the participants were allowed to touch the products,while the other half were asked not to touch them. The volunteers then were asked to express their sense of ownership of the products and to report how much money they were willing to pay for each. The results showed that those students who were allowed to touch the objects,reported significant increased levels of perceived ownership. They also expressed a desire to pay more money to obtain the products. The investigators also discovered that a sense of very pleasant feelings when touching products,determined how much money consumers were willing to pay. However,if the object did not feel pleasant to the touch,it significantly decreased the amount the buyers were willing to pay. Researchers said that many stores have already followed the right path. But what can be done while shopping online,when touching of an item is not possible? In this case,the experts say,just picturing in mind that they are touching it and then owning it,will cause greater feelings of ownership,and thus the consumers will be more likely to make a purchase. When you touch an object,you immediately feel some kind of a connection to it,according to the researchers. That connection stirs up an emotional reaction. And that emotion can make people buy something they would never even... Question: What led the researchers to conduct this study? - To illustrate the connection between touch and feelings of ownership. - To share their good ideas about avoiding impulsive consumption. - To develop marketing strategies for trade companies. - To satisfy customers' social needs when shopping.
A: To illustrate the connection between touch and feelings of ownership.
