Article: Think about what you usually have for a meal: Is it a hamburger? What about vegetables? Would it surprise you to learn that what you eat can affect the whole planet? It can--in a big way. Scientists attending the American Association for the Advancement of Science meeting in Chicago presented new studies showing how food and its production affect the globe and its warming climate. It is generally believed that global warming is caused by the large amounts of greenhouse gases released into the atmosphere. One of these greenhouse gases is carbon dioxide. What does this have to do with food? A big part of the carbon dioxide comes from the process of making and eating food, the scientists reported in Chicago. The production of meat contributes to a lot of that carbon dioxide. The process of making a hamburger, for example, requires a lot of energy. A cow has to be fed and raised on farmland, and cow manure is a major source of methane --an especially powerful greenhouse gas. By the time a hamburger is finally served on a dinner plate, it has done great harm to the environment. The message from the research is clear: We can greatly reduce the production of greenhouse gases by eating less meat. All kinds of meat, the scientists reported, are harder on the planet than vegetables. To grow and eat a pound of potatoes, for example, sends less than one-quarter pound of carbon dioxide or other greenhouse gases into the air. So shifting our diet to less meat and more vegetables ,as it turns out, may do the world some good. Question: Which of the following is NOT true? Yes or no, is the answer "To grow and eat vegetables does no harm to the environment."?
No

Article: How often one hears children wishing they were grown-ups and old people wishing they were young again. Each age has its pleasures and its pains, and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets. Childhood is a time when there are few _ to make life difficult. If a child has good parents, he is fed, looked after and loved, whatever he may do. It is impossible that he will ever again in his life be given so much without having to do anything in return. What's more, life is always presenting new things to the child -- things that have lost their interest for older people because they are too well-known. But a child has his parents. He is not so free to do what he wishes to do; he is continually being told not to do things or being punished for what he has done wrong. When the young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way that he used to as a child, he will go hungry. And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison. If, however, he works hard, keeps out of trouble and has good health, he can have the great happiness of building up for himself his own position in society. Question: The main idea of the passage is _ . Yes or no, is the answer "one is the happiest if he can make good use of each age in his life"?
No

Article: Mr King was the manager of a hotel. One weekend all the hotels in the city were full because there was a large meeting. On Friday night, three men came into the hotel and asked for rooms. Mr King said there were no rooms ready because of the meeting. The men were unhappy. Mr King wanted to help them. He remembered that Room 418, a very small room, was empty. He asked them if they would share a room. The three men said they would. Mr King said the room would be thirty dollars: ten for each one. Each man gave him the money and then went up to the room. Mr King soon began to feel sorry. "Thirty dollars is a lot to ask as price for that small room. " he thought. He called his assistant over and said, "Here is five dollars. Take it to the men in Room 418. I asked too much for their room." The assistant took the money. While he was on the way there, he started to think, "How can three men divide five dollars? I'll give them each only one dollar and keep the two dollars for myself. The men will be happy to get something back, and Mr King will never know. " So the assistant returned one dollar to each man. Each man had at first paid ten dollars. After the assistant returned them one dollar each, each had paid nine. There were three men, $ 9 x3 = $ 27. The assistant kept $ 2. $ 27 + $ 2 = $ 29. Where is the missing dollar? Question: Where is the missing dollar? Yes or no, is the answer "there wasn't any missing dollar."?
Yes
