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: What would be the best title for the passage? - University education in the US - University education challenged - Teaching and research in universities - Undergraduate teaching rediscovered
Undergraduate teaching rediscovered

English speakers are always creating new words, and we should be able to know where most words come from. Sometimes, however, no one may really know where a word comes from. Did you ever think about why hamburgers are called hamburgers, especially when they are not made with ham ? About a hundred years ago, some men went to America from Europe. They came from a big city in Germany called Hamburg. They did not speak good English. But they ate good food. When some Americans saw them eating round pieces of beef ,they asked the Germans what it was. The Germans did not understand the question and answered, "We came from Hamburg." One of these Americans owned a restaurant, and had an idea. He cooked some round pieces of beef like what the men from Hamburger ate. Then he put them between two pieces of bread and started selling them. Today "hamburgers" are sold in many countries around the world. Whether this story is true or not, it certainly is interesting. Knowing why any word has a certain meaning is interesting, too. The reason may be found in any large English dictionary. Question: According to the story, _ . - few Americans like hamburgers - hamburgers are made with beef - hamburgers are made with ham - Hamburgers were sold all over the world about a century ago.

In the 1960s and 70s, widespread tension developed in both British and American society, regarding issues such as women's rights and the Vietnam War. Lennon in particular became known for his message of peace and for his opposition to the war in Vietnam. This led to an attempt by former US president Richard Nixon to drive him away from the US. Lennon's second-wife Yoko Ono was also politically active. Lennon was also hugely admired for his musical abilities. Along with fellow-Beatle Paul, Lennon and McCartney were the Beatle's song-writing team.

In August, a bathroom from his last home in Britain, was auctioned for PS9,500.

Read the following article and select the best answer. Article: For years scientists have been worried about the effects of air pollution on the earth's natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse. Indoor air pollution can cause a person to feel tired, to suffer eye pain, headache and other problems. Some pollutants can cause breathing disorders, diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution. People have paid more attention to the problem now. It is true that when builders began making houses and offices they did not waste energy. To do this they build buildings that limited the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to let out harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building--green plants. Scientists do not really know how plants control air pollution. They believe that a plant's leaves absorb or take in the pollutants. In exchange the plant lets out oxygen through its leaves and tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and healthier place. Question: The indoor air pollution is caused by _ . - the limit of the flow of air between inside and outside - the building way that the builders want to save energy - the building things that are made of man-made materials - the man-made building materials and the limit of air-flow
(A).
the man-made building materials and the limit of air-flow
