Article: After numerous warnings over the years, you thought coffee probably had a negative effect on your health. Perhaps the drink is not so bad after all. The new study, conducted by the National Cancer Institute (NCI), has been published and suggests that coffee does not have a harmful effect on your health. Researchers suggest, based on data examined, older adults who drink a lot of coffee, have a lower risk of death when compared to their non-drinking coffee peers. The team of researchers conducting the study analyzed data on 400,000 U. S. men and women,aged 50 to 71 years; the individuals had participated in the NIH-AARP Diet and Health Study. This study started in 1995-1996 and was tracked until the day a participant passed away, or Dec. 31, 2008. According to a press release on the report, researchers shared that coffee drinkers are "less likely to die from heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections, although the relationship was not seen for cancer." Results indicated participants that drank three or more cups of coffee a day reduced their risk of death by 10 percent. Based on the findings that both caffeinated and non-caffeinated coffee found similar results, researchers are thinking caffeine is not the protective ingredient , although which ingredient in coffee might be, they are not sure. Researchers indicate that despite these observational findings, they caution it is not clear whether or not drinking coffee actually extends life expectancy. "Coffee is one of the most widely drunk drinks in America, but the relationship between coffee consumption and risk of death has been unclear. We found coffee consumption to be associated with lower risk of death overall, and of death from a number of different causes," said Neal Freedman, Ph. D., Division of Cancer Epidemiology and Genetics, NCI. "Although we cannot infer a relationship between coffee drinking and lower risk of death, we believe these results do provide some comfort that coffee drinking does not... Question: The passage is mainly about _ . Yes or no, is the answer "new study results on coffee"?

Article: GU Zhaodi, 60, had taken water for granted for years. In fact, no one in the beautiful lake city of Wuxi, Jiangsu Province had bothered to spare a thought on water. But all that changed dramatically overnight last month when taps in the city ran dry. Due to a blue-green algae outbreak in Taihu Lake, China's third largest freshwater lake and the source of drinking water for 4 million Wuxi residents ,water from the city's taps became dark and smelly. "I can't believe there is no water for drinking, let alone cooking and washing,"said Gu. The lake was blanketed with the algae, giving off a strong smell of rotting meat. A stone thrown into it took a long time to sink. Experts said that algae usually boom because of hot water and rich chemicals like phosphor in the water. "High temperature and a lack of rain in the past few months helped the growth of algae,"said Zhang Lijun, an official from the State Environment Protection Administration. "However, pollution from human activity should be most blamed for the disaster." Taihu Lake is surrounded by many small factories, which _ in the 1980s.Inthe 1990s,many foreign-funded companies joined in. The industries prospered ,Wuxi has grown into one of the wealthiest cities in East China. But that came at the price of pollution. The lake was treated like a waste dump ,with factories emptying industrial waste and untreated sewage into it. Although, after the government's effort, life in the city has gone back to normal, the one-week crisis rang a bell for the government and local people."It's time to rebuild the beauty of nature, or our lives will be at risk,"said Gu. "A safe environment comes first. Economic growth will be nothing without fresh water to drink and clean air to breathe." said China Daily. Question: According to the passage ,Taihu Lake _ Yes or no, is the answer "suffered from industrial waste,untreated sewage and algae."?

Ques: Article: The financial crisis is reminding Americans of a lesson they first learned in childhood: Share and share alike. They are sharing or swapping tools and books, cars and handbags, time and talent. The renewed desire to share shows up in a variety of examples: A car-sharing service has had a 70 percent membership increase since the crisis occurred. Some companies encouraged his employees to take vanpooling. Governments are putting bikes on the street for public use. How-to-swap Web sites are increasing quickly. The economy reflects the way Americans have cut back, especially on daily items: Department store sales dropped 1.3 percent in June. People are not buying cars, and as a result, auto sales dropped 27.7 percent last month. They are not paying others to do what they can do themselves -- Home Depot reports increased attendance at in-store do-it-yourself clinics. And although paint sales are down in general, according to Sherwin-Williams, individual consumers are still buying. When Tom Burdett needed to cut some tiles at his home outside Annapolis, he refused to buy expensive tools. So he asked his neighbors and friends for help. Sure enough, someone had just what he needed. And when that friend needed help fixing a satellite dish, Burdett volunteered to help. The sharing mind-set is not new to the American culture, but many Americans give it up when the nation changed from an agricultural society to an industrial one, said Rosemary Hornak, a psychology professor at Meredith College in Raleigh, N.C. They moved farther from their families and did not have time to connect with new neighbors because they worked so much, she said. Neighborhood conversations tell more of the story as the movement grows organically in communities across the Washington region and the nation. On one street in Arlington, for example, neighbors are collecting their separate money for mulch and dividing it among themselves. Question: It can be inferred from the passage that _ . Yes or no, is the answer "more and more Americans solve problems in their daily life by helping each other ."?
Ans: Yes

Question: Article: President Coolidge's statement, "The business of America is business," still points to a very important truth today -- that business organizations have more prestige in American society than any other kind of organization, including the government. Why do business institutions still possess this great prestige? One reason is that Americans view business as being more firmly based on the idea of competition than other organizations in society. Since competition is seen as the main source of progress and development by most Americans, competitive business organizations are respected. Competition is not only good in itself; it is the means by which other basic American values, such as individual freedom, equality of opportunity, and hard work are protected. Competition protects the individual freedom by making sure that there is no monopoly of power. Compared with one and all-powerful government, many businesses compete against each other for benefit. If one business tries to take unfair advantage of its customers, it will lose to the competing business which treats its customers more fairly. Since there are many businesses competing for the customers' dollars, they cannot afford to treat them unfairly and the customers would lose nothing.A contrast is often made between business, which is competitive, and government, which is a monopoly. Because business is competitive, many Americans believe that it gives more support for freedom than government, even though government leaders are elected by the people while business leaders are not. Many Americans believe that competition is as important, or even more important, as democracy in protecting freedom. Competition in business is also believed to strengthen the idea of equal opportunities. Competition is seen as an open and fair race where success goes to any person regardless of his or her social class background. Competitive success is commonly seen as the American choice of the higher social position which is not based on one's family background. Business is... Question: Who can benefit from business competition? Yes or no, is the answer "Customers of those businesses."?
Answer:
No
