user: Article: A drunk walks into a bar and says to the waiter, "Waiter, buy everyone in the house a drink, pour yourself one, and give me the bill." So the waiter does just that and hands the man a bill for $57. The drunk says, "I haven't got it." The waiter slaps the guy around a few times, then throws him out into the street. The very next day the same drunk walks into the bar and once again says, "Waiter, buy everyone in the house a drink, pour yourself one, and give me the bill." The waiter looks at the guy and figures _ to _ himself that he can't possibly be stupid enough to play the same trick twice, so he gives him the benefit of the doubt, pours a round of drinks for the house, has a drink himself and hands the drunk a bill for $57. The drunk says, "I haven't got it." The waiter can't believe it. He picks the guy up, beats the living daylights out of him, then throws him out into the street. The next day the same drunk walks back into the same bar and says, "Waiter, buy everyone in the house a drink and give me the bill." In disgust  , the waiter says, "What? No drink for me this time?" The drunk replies, "You? No way! You get too violent when you drink." Question: Why does the waiter the second time give everyone in the house a drink, including himself? Yes or no, is the answer "Because he thinks the drunk wouldn't play the same trick twice."?

Article: When my dad was a very young man, he was one of the few people in the small community of North Apollo, who owned a car. When he and Mom got married, they went on their honeymoon in that old Ford, but they had to turn around and pay a visit to the garage because the car didn't have enough power to drive them going forward. When I was too young to remember, my dad owned a truck in which we all went nutting and berry picking. It was an important day when Daddy decided to buy a family car. It must have been about 1937 or 1938 when he purchased a 1929 Chevrolet sedan. We loved that old car. On Saturday evenings, after dinner, the whole family would pile into that old square sedan, go up to Whitlinger's grocery store and buy a bag of Hershey's Kisses. Then Daddy would head out toward the country and drive all around the old country roads while we fed ourselves on chocolates. That was the highlight of our week. I didn't know which we enjoyed most, the chocolates or riding in the car. The first car I owned was a Packard touring car. My cousin Janet and I were living in Washington D.C., and mostly rode the streetcars to wherever we wanted to go. Janet's friend Kathy had learned to drive so the three of us decided to buy a car for ourselves. We picked out this old Packard because it was all we could afford. Every American living today can tell stories about the cars they have driven. I love to drive. I am most excited when I'm headed to the garage with my car keys in my hand. The car I own now is a 1998 Buick Century with a mark where I backed into a tree. I love the freedom I feel just moving down the road in that old car. I am almost certain that when I get to heaven, God will have that old car sitting there waiting for me to drive down that golden street. Question: The author decided to buy his own car because   _  . Yes or no, is the answer "he wanted to change his way of getting around"?
(Answer)
Yes


Ques: Article: For the most part, schools are designed to produce people who fit into society, not people who set out to change it. However, schools, particularly universities, may not only spread culture; they may add to the cultural heritage. Today American society places a good deal of emphasis on the development of new knowledge, especially in the physical and biological sciences, medicine, and engineering. In recent years, the nation's leading universities have increasingly become research centres. An emphasis on research has led universities to judge professors not by abilities as teachers, but as researchers. Promotions, salary increases, and other benefits have long been dependent on research and publication. However, the most important is no longer publishing. To be successful these days, professors have to bring in money provided by government and private industry. Critics claim that academic success is most likely to come to those who have learned to "ignore" their teaching duties to pursue research activities. Defenders say that even when students themselves are not involved in research projects they benefit from such an emphasis on research.  Major research universities like the Massachusetts Institute of Technology have also cooperated with industrial companies to develop technology and products with commercial potential. With university-industry ties continuing to grow, debate has increased about the consequences for basic science, academic openness, the control of information, the direction of research, and the influence on students. Question: The author seems to be   _   the move of emphasis to research. Yes or no, is the answer "neutral about"?
Ans: No


Article: Zoo elephants don't live as long as those in the wild, according to a study sure to cause debate about keeping the giant animals on display. Researchers compared the life spans of elephants in European zoos with those living in Amboseli National Park in Kenya and others working on a timber enterprise in Buma. Animals in the wild or in natural working conditions had life expectancies twice than or more of their relatives in zoos. Animal care activists have urged in recent years to discourage keeping elephants in zoos, largely because of the lack of space and small numbers of animals that can be kept in a group. The researchers found that the _ life span for African elephants in European zoos was 16.9 years, compared with 56 years for elephants who died of natural causes in Kenya's Amboseli Park. Adding in those elephants killed by people in Africa lowered the median life expectancy there to 35.9 years. For the more endangered Asian elephants, the median life span in European zoos was 18.9 years, compared with 41.7 years for those working in the Burma Timber Enterprise. Median means half died younger than that age and half lived longer. There is some good news, though. The life expectancies of zoo elephants have improved in recent years, suggesting an improvement in their care and raising, but "Protecting elephants in Africa and Asia is far more successful than protecting them in Western zoos." There are about 1,200 elephants in zoos, half in Europe, researchers concentrated on female elephants, which make up 80 percent of the zoo population. One amazing thing was that Asian elephants born in zoos had shorter life spans that those brought to the zoos from the wild. Zoos usually lack large areas that elephants are used to in the wild, and that zoo animals often are alone or with one or two other unrelated animals, while in the wild they tend to live in related groups of 8 to 12 animals. In Asian elephants, baby death rates are two to three times higher in zoos than in the Burmese logging camps, and then, in... Question: Which of the following is Not the disadvantage of keeping elephants in zoos? Yes or no, is the answer "Less attention."?
