Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Before 1900, many theories existed as to the cause of yellow fever . Some doctors were sure the disease was air-borne; others felt that it was spread from person to person.

Walter Reed,all American doctor sent to study yellow fever in Cuba,went to talk with Finlay.Reed,after reading a lot on the subject,had begun to think that Dr.Finlay might be fight.Then Reed and his comrades set to work at once.Outside Havana,they set up a laboratory and began experiments to test the theory.The experiments were successful.Now we know:A period of about two weeks must pass before a mosquito,after feeding on a sick person,could infect another person.The sick person had to have yellow fever a certain number of days before the mosquito biting him was able to carry the disease.

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Asia has long tradition of tea- drinking. And China is no exception. However, lately more and more Chinese people are turning to a different drink. Coffee has become an increasingly popular choice of Chinese people living abroad and in the country's huge cities. It is also a popular crop among those living in the mountains of southern Yunnan Province. In big cities such as Beijing, coffee shops seem to be on nearly every major street corner. These shops are not just selling drinks from Starbucks, the world-famous coffee company. Coffee businesses from South Korea, Taiwan, HongKong and Britain are also operating in China. Tea-drinking is steeped in the culture and traditions of many countries, like China and Japan. But is that changing? Are young people from Asia now choosing a cup of coffee instead of tea? BeiBei Su is from China. She has been living in the United States for the past eight years. Before that, she lived in Italy for two years. Ms. Su says she likes tea better than coffee. But she adds that may not be true among the young generation in China. Many young Chinese people drink coffee socially --when meeting with friends. Yang Lin lives in the U.S. but comes from an area in China famous for growing tea. She used to only drink tea while in China. But now, she says, she drinks both and for different reasons. Yang Lin says that drinking coffee for her is a social event. She and her co-workers like to sit in a cafe and talk over a cup of coffee. Voyo is another Chinese woman who now lives in Washington, D.C. She says that after moving to the U.S. Her tastes changed. We would call her a coffee _ , someone who now chooses to drink coffee. With more people drinking coffee, many see an economic opportunity for Chinese -grown beans. China-grown coffee could be a money- maker even if most of the coffee on sale in China is imported. Question: Why does YangLin drink coffee? Options: A: Because she lives in the U.S. Now. B: Because she can talk with friends. C: Because she has drunk tea so long. D: Because her tastes has changed.
Answer: B

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Singles' Day ---- the Chinese opposite of Valentine's Day has turned into a massive online shopping event. It is a day when single people are supposed to buy themselves presents. But there are sociological reasons behind China's "celebration" of single life. And the imbalance could have big consequences for the country. There were 34 million more men than women in China in 2011. Part of that is natural - usually there are 105 boys born for every 100 girls. But the Chinese gender ratio at birth is much more obvious. It was 116 boys to 100 girls in 2012. The one child policy is largely to blame. Brought in to limit population expansion, the policy allows only one child per family. But because male children are seen as more valuable, as well as more likely to support their parents in old age, some parents choose to have a son over a daughter. The result is that large numbers of men will likely never get married. In fact, one study has predicted that by 2030, 1 in 5 Chinese men in their 30s will never have married, while another states that 94% of unmarried people in China are men. Traditionally, China has seen high levels of marriage, usually among the young. Besides, the increased education and career opportunities for women have meant that marriages are happening later. It is also traditional that women often marry men of a higher socioeconomic status than themselves. So women at the top and men at the bottom find themselves alone. One study has even suggested a link between an imbalanced gender ratio and growth in violent crime in the country. Singles' Day can't solve all the problems China's singles face. Indeed, it is possible that it is causing even more problems, as men resort to increasingly risky lines of work to increase their chances of gaining money and thus a wife. I am worried that as money starts to overcome romance, there is evidence that China's marriage market is increasingly materialistic. Question: In 2012, if 50 girls were born, how many boys were probably born? Options: A: 50. B: 52. C: 58. D: 60.
