Read the article and select the best answer. Article: A sense of humor is just one of the many things shared by Alfred and Anthony Melillo, 64-year-old twin brothers from East Haven who made history in February 2002. On Christmas Eve, 1992, Anthony had a heart transplant from a 21-year-old donor. Two days before Valentine's Day in 2002, Alfred received a 19-year-old heart, marking the first time on record that twin adults each received heart transplants. "I'm 15 minutes older than him, but now I'm younger because of my heart and I'm not going to respect him," Alfred said with a big smile, pointing to his brother while talking to a roomful of reporters, who laughed frequently at their jokes. While the twins knew that genetics might have played a role in their condition, they recognized that their eating habits might have also contributed to their heart problems. "We'd put half a pound of butter on a steak. I overdid it on all the food that tasted good, so I guess I deserved what I got for not dieting properly." The discussion moved to Anthony's recovery. In the five years since his heart transplant, he had been on an exercise program where he regularly rode a bicycle for five miles, swam each day, and walked a couple of miles. He was still on medication, but not nearly as much as Alfred, who was just in the early stage of his recovery. "Right now I feel pretty young and I'm doing very well," Anthony said. "I feel like a new person." Alfred said his goal, of course, was to feel even better than his brother. But, he added, "I love my brother very much. We're very close and I'm sure we'll do just fine." Question: This article is mainly about _ . Options: A: the danger of heart transplanting B: becoming young by getting a new heart C: the effect of genetics on the heart D: the twin brothers who received heart transplants

Read the article and select the best answer. Article: Humans are social animals. They live in groups all over the world. As these groups of people live apart from other groups, over the years and centuries they develop their own habits and ideas, which form different cultures. One important particular side of every culture is how its people deal with time. Time is not very important in nonindustrial societies. The Nuer people of East Africa, for example, do not even have a word TIME that is in agreement with the abstract thing we call time. The daily lives of the people of such nonindustrial societies are likely to be patterned around their physical needs and natural events rather than around a time schedule based on the clock. They cook and eat when they are hungry and sleep when the sun goes down. They plant crops during the growing seasons and harvest them when the crops are ripe. They measure time not by a clock or calendar ,but by saying that an event takes place before or after some other event . Frequently such a society measures day in terms of"sleeps"of longer periods in terms of"moons".Some cultures, such as the Eakinos of Greenland measure seasons according to the migration of certain animals. Some cultures which do not have a written language or keep written records have developed interesting ways of"telling time".For example, when several Australian aborigines want to plan an event for a future time, one of them places a stone on a cliff or in a tree. Each day the angle of the sun changes slightly. In a few days, the rays of the sun strike the stone in a certain way. When this happens, the people see that the agreed-upon time has arrived and the event can take place. In contrast ,exactly correct measurement of time is very important in modern, industrialized societies. This is because industrialized societies require the helpful efforts of many people in order to work. For a factory to work efficiently(well, quickly and without waste),for example, all of the workers must work at the same time. YCTherefore, they must know what time to start...

(Question)
Read the article and select the best answer. Article: I have a friend named John Roberts who owns a horse ranch in San Ysidro.The last time I was there he shared a story with me. "It is a story about a young man who was the son of an itinerant horse trainer. When he was a senior,he was asked to write a paper about what he wanted to be and do when he grew up." That night he wrote a seven-page paper describing his goal of someday owning a horse ranch. He wrote about his dream in great detail and he even drew a diagram of a 200-acre ranch, showing the location of all the buildings,the stables and the track. "The next day he handed it in to his teacher. Two days later he received his paper back. On the front page was a large red F with a note that read, 'See me after class.'" "The boy went to see the teacher after class and asked, 'Why did I receive an F?'" "The teacher said, 'This is an unrealistic dream for a young boy like you. You have no money. You come from an itinerant family. You have no resources. Owning a horse ranch requires a lot of money. You have to buy the land. You have to pay for the original breeding stock and later you'll have to pay large stud fees. There's no way you could ever do it.' Then the teacher added, 'If you will rewrite this paper with a more realistic goal, I will reconsider your grade.'" "The boy went home and asked his father what he should do. His father said, 'Look, son, you have to make up your own mind on this. However, I think it is a very important decision for you.'" "Finally,after sitting with it for a week, the boy turned in the same paper, making no changes at all. He stated, 'You can keep the F and I'll keep my dream.'" John continued, "I tell you this story because you are sitting in the middle of my 200-acre horse ranch. I still have that school paper framed over the fireplace." He added, "If I had changed my paper at that time, maybe we would not have the chance to be here talking about the dreams ." Question: John's father respond to his son's puzzlement by _ . Options: A: By criticizing his decision. B: By helping him make the decision. C: By encouraging him to make decision himself. D: By praising him brave.
