Article: This year some twenty-three hundred teenagers (young people aged from 13 to 19) from all over the world will spend about ten months in US homes. They will attend US schools, meet US teenagers, and form impressions of the real America. At the same time, about thirteen hundred American teenagers will go to other countries to learn new languages and gain a new understanding of the rest of the world. Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George's family. In turn, George's son Mike spent a year in Fred's home in America. Fred, a lively young man, knew little German when he arrived, but after two months' study, the language began to come to him. Schools were completely different from what he had expected--much harder. Students rose respectfully when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities. Family life, too, was different. The father's word was law, and all activities were around the family rather than the individual . Fred found the food too simple at first. Also, he missed having a car. "Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it." At the same time, In America, Mike, a friendly German boy, was also forming his idea."I suppose I should criticize American schools," he says. "It is far too easy by our level. But I have to say that I like it very much. In Germany we do nothing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens . There ought to be some middle ground between the two. Question: The world exchange programme is mainly to _ . Yes or no, is the answer "let students learn something about other countries"?
No

Article: Mr. Hungerton, her father, really was absolutely centered upon his own silly self. If anything could have driven me from Gladys, it would have been the thought of such a father-in-law. I am convinced that he really believed in his heart that I came round to the Chestnuts three days a week for the pleasure of his company, and very especially to hear his views upon bimetallism . For an hour or more that evening I listened to his tiring talk about bad money driving out good, and the true standards of exchange. "Suppose," he cried, "that all the debts in the world were called up at once, and immediate payment insisted upon,--what under our present conditions would happen then?" I gave the self-evident answer that I should be a ruined man, upon which he jumped from his chair, scolding me for my thoughtless quickness, which made it impossible for him to discuss any reasonable subject in my presence. At last I was alone with Gladys, and the moment of Fate had come! She sat with that proud, delicate figure of hers outlined against the red curtain. How beautiful she was! Gladys was full of every womanly quality. I was about to break the long and uneasy silence, when two critical, dark eyes looked round at me, and the proud head was shaken disapprovingly. "I have a feeling that you are going to propose, Ned. I do wish you wouldn't; for things are so much nicer as they are." I drew my chair a little nearer. "Now, how did you know that I was going to propose?" I asked in wonder. "Don't women always know? Do you suppose any woman in the world was ever taken unawares? But--oh, Ned, our friendship has been so good and so pleasant! What a pity to spoil it! Don't you feel how splendid it is that a young man and a young woman should be able to talk face to face as we have talked?" She had sprung from her chair, as she saw signs that I proposed to announce some of my wants. "You've spoiled everything, Ned," she said. "It's all so beautiful and natural until this kind of thing comes in! It is such a pity! Why can't you control... Question: Why did the writer often come round to the Chestnuts? Yes or no, is the answer "To find the opportunity of staying with Gladys."?
No

Article: How can you find out what is going on inside a person's body without opening the patient's body up? Regular X rays can show a lot. CAT scans can show even more. They can give a complete view of body organs. What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient's body. Doctors use X rays to study and determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed. A CAT scanner, however, uses a group of X rays to give a cross-sectional view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear "photos" of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can "stop the action", giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient. Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don't cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays. CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives. Question: The best title of this passage might be_. Yes or no, is the answer "New X-ray Machine to Save Lives"?
No
