Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Mail was usually carried west on ships that sailed around the bottom of South America and then north to California.That could take several months. So, in eighteen fifty-seven, D.C.Lawmakers in Congress in Washington wanted to make it possible to send mail all the way across the United States by land.Congress offered to help any company that would try to deliver mail overland to the West Coast. A man named John Butterfield accepted this offer. He developed plans for a company that would carry the mail--and passengers, too. Congress gave John Butterfield six hundred thousand dollars to start his company. In return, he had to promise that the mail would travel from Saint Louis, Missouri, to San Francisco, California, in twenty-five days or less. It was not possible to travel straight through because of the Rocky Mountains and the deep snow that fell in winter. So the stagecoach would travel south from Saint Louis to El Paso, Texas, then over to southern California, then north to San Francisco. The distance was about four thousand five hundred kilometers. Two hundred of these stations were built, each about thirty-two kilometers apart. The workers were to quickly change the horses or mules whenever a stagecoach reached the station. There could be no delay. Each stagecoach was to travel nearly two hundred kilometers a day. One hundred stagecoaches were built and painted red or dark green. They were the most modern coaches that money could buy. They were designed to hold as many as nine passengers and twelve thousand pieces of mail. The seats inside could be folded down to make beds. Passengers either slept on them or on the bags of mail. The cost would be one hundred fifty dollars to travel from Saint Louis to San Francisco. If a passenger was not going all the way, the cost was about ten cents a kilometer. The passengers had to buy their own food at the stations. The stagecoach would stop for forty minutes, two times a day. The company warned passengers about the possible dangers. A poster said: "You will... Question: What can we learn from the passage? Options: A: John Buttterfield got thousands of dollars for delivering mail in stagecoaches. B: John Buttterfield kept his promise to deliver mail straight to the West Coast. C: Passengers might be robbed by Indians when traveling through the West. D: Passengers needed to pay one hundred dollars for their journey.
Answer: C

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: In many romantic movies or TV shows one scene always appears. It involves a handsome man standing outside a young woman's window, singing a love song to her to win her over. However, trying to woo a female with songs is not just something that humans do. A few animals sing love songs as well. Birds and elephants are romantic but the latest animal to _ a female might surprise you--it is the humble mouse. You may find it odd to find out that mice sing. We do not hear them because the frequency of their voice is so high. In fact, scientists have known for some time that male mice make special sounds to females, but it has always been assumed that the sounds are produced instinctively and randomly, with little thought going into the process. But new research suggests otherwise. When male mice with different voices were put in a cage together, scientists found that they would gradually change their pitches to sound like one another. But when a female mouse was put in the cage with two males, one male would change his pitch to match the other. "It was usually the smaller animal changing the pitch to match the larger animal," professor Erich Jarvis, leader of the study, from Duke University, US, told BBC News. This ability, known as vocal learning, is rare in the natural world. It had been thought to be limited to some birds, such as parrots--as well as whales and dolphins. The latest findings challenge the long-held opinion that mice cannot learn to adapt their voices. Scientists also found the part of the brain that controls the mice's singing ability. In the experiment, they damaged the cells in this part of the mice's brain and found that the animals couldn't keep their songs in pitch or repeat them any more. This also happened when the mice became deaf. Jarvis said that this finding had changed his understanding of the way mice make sound. "In mice we find that the pathways that are at least modulating these vocalizations are in the forebrain, in places where you actually find them in humans,"...

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: When Mrs.Joseph Groeger died recently in Vienna,Austria,people asked the obvious question,"Why did she live to be 107?" .Answers were provided by a survey conducted among 148 Viennese men and women who had reached the age of 100.Somewhat surprising was the fact that the majority had lived most of their lives in cities.In spite of the city's image as an unhealthy place,city living often provides benefits that country living can lack.One factor seems to be important to the longevity of those interviewed. This factor is exercise.In the cities it is often faster to walk short distances than to wait for a bus.Even taking public transportation often requires some walking.Smaller apartment houses have no elevators ,and so people must climb stairs.City people can usually walk to local supermarkets. Since parking spaces are hard to find,there is often no alternative to walking. On the other hand,those who live in the country and suburbs do not have to walk every day.In fact,the opposite is often true.To go to school,work,or almost anywhere else,they must ride in cars. Question: The Vienna survey may help to explain _ Options: A: the complaints of people in apartment houses B: the cause of Mrs Groeger's death C: the longevity of people like Mrs.Groeger D: the image of cities in general
Answer:
C
