Article: Exercise is one of the few factors with a positive role in long-term control of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical efforts. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to lose weight said they were combining exercise with their diet. In rejecting exercise, some people may be discouraged too much by caloric-expenditure charts; for example, one would have to quickly walk hard three miles just to work off the 275 calories in one delicious Danish pastry . Even exercise professionals accept half a point here. "Exercise by itself is a very tough way to lose weight," says York Onnen, program director of the President's Council on Physical Fitness and Sports. Still, exercise's supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight. If you have been sedentary and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year's time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.
Question: What is said about the average American in the passage?

Since the shows changed every six months, he was challenged by the need to continually develop new material.

By 1928 the popular nightspot began radio broadcasts. From the broadcasts Ellington and his orchestra gained a national reputation.

Article: Chinese writer Mo Yan's Noble Prize for Literature on Thunday might set off an explosion of global interest in Chinese literature and lead to more titles being translated into English. Chinese literature has alyeady attracted international attention, but experts say translation remains a barrier. "Many very good Chinese writers have been accepted globally for a long time already."says Michel Hockx, professor of University of London. " It's mainly because there are many more opportunities for Chinese writers to visit other countries, to publish their work outside China and to interact with readerships abroad. At the same time, more and more people globally are learning Chinese and taking an interest in Chinese language and Chinese culture." Hockx adds: "We need more good translators, especially foreign translators, who know good Chinese and can translate the work into their own languages in a way that foreign readers will appreciate and understand." London's independent literary agent Toby Eady, who represents many Chinese writers, including Yu Dan, met Mo about 15 years ago in China. But Eady says:"I still think Mo Yan's writing--and, to an extent, all Chinese writing--are not truly understood by Western readers because a part of Chinese literature is lost in translation. The translator has done a good job in translating Mo's work, but the variety of Chinese vocabulary doesn't well translate into English." University of Oxford lecturer in medern Chinese literature Margaret Hillenbrand says:"The obvious reason for the growing global presence of Chinese literature is the growing global presence of China itself. People have come to realize that there is a serious knowledge deficit between China and its international counterparts --in particular, China knows incomparably more about Europe and America than the other way around--and reading Chinese literature is an effective means of narrowing that gap."
Question: One of the reasons why Chinese literature has been accepted globally is that _ .
Options: (A) more Chinese writers can express themselves in English freely (B) Chinese visitors are enjoying more chances to go abroad (C) the westerners have become more interested in Chinese literature (D) more western readers can interact with each other
