*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: Jerry Morris died on 28 October 2009. He was 99 years old. You have probably never heard of him. He was a professor of public health. More than 50 years ago he produced one of the most famous epidemiological papers of the 20th century. His study showed that bus conductors were much less likely to die of heart disease than bus drivers. Why? Because the conductors spent their working day walking. It seems obvious now but in the middle of the last century doctors were puzzled by the rising numbers of people who got heart diseases. Jerry Morris found one of the main causes: a sedentary lifestyle. He started exercising for a few minutes each day and lived until his 100th year. If you wish to protect your heart, you have to do more than wander in the garden. The exercise needs to be reasonable. Jogging is not for everyone and a round trip to the gym takes a couple of hours, plus the monthly membership fee is only good value if you visit regularly. The answer is simple: walk. A half-hour purposeful walk five times a week will lower your risk of heart disease, diabetes and strokes. Older people sometimes feel they have left it too late. But it is never too late to start and there are no upper age limits. Start gently. Take your time: a 15-minute flat walk in the nearest park, four or five times a week. Within a month or so, you are already beginning to protect your heart. Build the walks up. When you can comfortably walk for half an hour in the park, go further: try following rivers and canals. Regular walkers have their own natural gymnasium. There is no membership fee, just some of the finest scenery in the world. Great Britain is the walker's gym. When you have followed the rivers and canals, and are enjoying walking for a couple of hours, head for the coast. Once again, build it up slowly. When you are comfortable with long coastal walks, you can think of our national parks. Question: What might be the best title for this passage? Options: A: Long Life Comes from Walking B: Walking Helps Cure Heart Disease C: A Walk a Day Keeps the Doctors away D: An Hour's Walk in Nature is Worth Two in the Gym

C

*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: Washoe, a female chimpanzee believed to be the first non-human to acquire human language, has died of natural causes at the research institute where she was kept.The chimp died on Tuesday night, according to Roger and Deborah Fouts, co-founders of The Chimpanzee and Human Communications Institute in Washington, where she lived. Washoe was born in 1965 in Africa, where she was captured by the Air Force and taken to the US for research use in the space program. In 1966, she left the program and began living with two scientists, Allen and Beatrix Gardner, who led a project to teach the chimp American Sign Language (ASL) in Washoe, Nevada, for which it was named. Washoe had been living on Central Washington University's Ellensburg Campus since 1980. She had a vocabulary of about 250 words. Also, Washoe taught sign language to three younger chimps: Tatu, 31, Loulis, 29, and Dar, 31 Primate researcher Jane Goodall, in Fouts' book Next of Kin, noted the importance of the work with Washoe. "Roger, through his ongoing conversations with Washoe and her extended family, has opened a window into a chimpanzee's mind," Goodall said. Though previous efforts to teach chimps spoken languages had failed, the researchers believed there was a better chance using signs. But Washoe's language skills were disputed by scientists who believed that language is unique to humans. Among those who doubted that chimps could use language were linguist Noam Chomsky and Harvard scientist Steven Pinker. They believed primates simply learn to perform certain acts in order to receive rewards, and do not acquire true language. Question: What can be inferred from the passage? Options: A: The ASL project was first set up in Africa for the study on Washoe. B: Washoe may communicate with other chimps by signing. C: Washoe must have been able to speak 250 words or so. D: The researchers will prove that most chimps could use language.

I'm taking a test and have to guess the right answer to the question after the article. Article: Some good news for online holiday shoppers: bargain-hunting binges will drive prices down as web-based retailers compete to offer bigger discounts, marketing researchers predict. A recent survey by Shopzilla found that nearly 84 percent of online retailers would offer Cyber Monday discounts, up 12 percent from last year. Cyber Monday, the first Monday after Thanksgiving, is the online response to Black Friday, the day after Thanksgiving when stores are traditionally flooded with customers, some of whom camp at the entrances overnight to take advantage of discounts. However, in the current economic climate, online retailers have felt pressure to offer sales and discounts even before Black Friday. But how online retailers decide to offer those big savings isn't a simple matter of trying to attract the consumers who are watching their wallets, Bohlmann of Sabanci University in Istanbul says. Online stores will also pay attention to the deals their competitors are offering, potentially leading to price wars between certain retailers to attract all those potential bargain-hunting customers. Online shoppers can be divided into two types, Bohlmann said, --switchers and --loyals. Switchers compare prices between retailers and go for the cheapest one, while loyals stick to one brand or store. It almost doesn't matter what price you charge. Online retailers will look at the percentage of switchers and loyals they have in order to decide whether to offer discounts. The more switchers they have, the more likely they will offer discounts. But retailers don't just look at the percentage of their own customers; they also look at the competition. If one online store has a higher percentage of loyals than the competitor, it can afford to keep prices higher. On the contrary, if it has a higher percentage of switchers than the competitor, it might want to lower prices. Question: It can be inferred from the text that _ Options: A: retailers should know more about customers' interest B: There will be no shoppers who go out in crowds C: Barnes&Noble's prices are lower than other companies' D: Retailers like the switchers more than the loyals
