Read the following article and select the best answer. 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 findings show that _ . - people who often drink coffee are more likely to get cancer. - people rely heavily on coffee drinking and that proves to be a problem - drinking coffee can help reduce the risk of death from some diseases - caffeine is the very ingredient which protects people from disease.
drinking coffee can help reduce the risk of death from some diseases

Read the following article and select the best answer. Article: A major new development in system of work in Britain is taking place. Flexible working hours, or "Flextime", are catching on fast, and trend is continuing. In 1973, over 500 organizations had adopted the idea, and by 1974, this number had risen to over 200,000. Flexible working hours were invented in Germany in the late 1960's, but reached Britain only in 1972. The system allows workers to start and finish work whenever they want, with only two requirements. These are, firstly, that all workers must present for certain "key" times in the day, and secondly, that all workers must work an agreed total number of hours per week. The system had proved a total success wherever it has been tried. A survey of 700 workers on flexible hours showed three main advantages: a better balance between working and private life, avoidance of the need to travel during rush hours and the ability to finish a certain task before leaving. From the employer's point of view, the system tends to increase productivity, reduce labour turnover and give workers a greater sense of duty. At first, "Flexible" was mainly confined to white-collar workers, but it is now being applied to manual workers too. Question: According to "Flextime" system, workers need not _ . - work at the same time - work all the weekdays - work hard - ask for leave when being absent
(Answer)
work at the same time

Ques: Read the following article and select the best answer. 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 _ . - more and more Americans solve problems in their daily life by helping each other . - if the prices of service goes down, individual consumers won't do something themselves. - the sharing-mind set is a strange to many Americans. - when the crisis ends, Americans will abandon the sharing-mind set.
Ans: more and more Americans solve problems in their daily life by helping each other .

Question: Read the following article and select the best answer. 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...
