input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: The best swimmers tend to be tall and thin with long arms, long legs, long feet, and long hands. The size of their hands gives them great "water grasp", and only a very small hand movement keeps them afloat. They also have great strength, endurance, insulation against heat loss while in water below body temperature, thus better energy conservation, low resistance when in the water, and swimming stroke mechanics . Part of the reason why some people are better swimmers than others has to do with body density. The average person's body density is slightly less than that of water. Muscle has greater density than fat. Therefore, very muscular people tend to be poor at staying afloat. Bone has greater density than fat. Therefore, very skinny people tend to be poor at staying afloat. Good buoyancy is not necessarily the most important factor in good swimming, but it certainly helps. For example, great competitive swimmers--tall, thin, and usually more muscular than average--tend to have greater body density than average and less buoyancy. Many would not float very well if they remained motionless in the water. Their much greater "water grasp" makes up for it. www.ks5u.com The average woman contains a higher proportion of fat in her body than the average man, and the average man contains a higher proportion of muscle in his body than the average woman. Therefore, in general, women are better floaters than men. Compared with other competitive sports, the performance of women is closer to that of men in competitive swimming. Options: A By reasoning and explaining. B By argument and debate. C By explaining one part after another. D By examples and comments. Answer: C By explaining one part after another. Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Psychologists take opposing views of how external rewards, from warm praise to cold cash, affect motivation and creativity. Behaviorists, who study the relation between actions and their consequences, argue that rewards can improve performance at work and school. Cognitive researchers, who study various aspects of mental life, maintain that rewards often destroy creativity by encouraging dependence on approval and gifts from others. The latter view has gained many supporters, especially among educators. But the careful use of small monetary rewards sparks creativity in grade-school children, suggesting that properly presented inducements indeed aid inventiveness, according to a study in the June Journal of Personality and Social Psychology. "If kids know they're working for a reward and can focus on a ly challenging task, they show the most creativity," says Robert Eisenberger of the University of Delaware in Newark. "But it's easy to kill creativity by giving rewards for poor performance or creating too much anticipation for rewards." A teacher who continually draws attention to rewards or who hands out high grades for ordinary achievement ends up with uninspired students, Eisenberger holds. As an example of the latter point, he notes growing efforts at major universities to tighten grading standards and restore failing grades. In earlier grades, the use of so-called token economies, in which students handle challenging problems and receive performance-based points toward valued rewards, shows promise in raising effort and creativity, the Delaware psychologist claims. Options: A rewarding poor performance may kill the creativity of students B punishment is more effective than rewarding C failing uninspired students helps improve their overall academic standards D discouraging the students' anticipation for easy rewards is a matter of urgency Answer: A rewarding poor performance may kill the creativity of students Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: When I started a degree in English language, I hadn't intended to study abroad, not to mention starting learning German. But having recently returned from my year abroad in Germany, I can say that making the effort to learn the language really enriched my experience. With language translation technology advancing all the time, it's convenient to rely on Google Translate and smartphone apps without having to learn the language. But a second language shouldn't be a luxury . Researchers have discovered that much language learning can increase the size of your brain in as little as three months. From my own experience, learning the language lets you travel beyond the well-known tourist paths, gain a real student experience and widen your social network beyond the international circle. The process of learning German abroad was completely different from my language course at university, where students sat quietly and stumbled through spoken exercises. Instead, language learning abroad was energetic and part of my lifestyle - from chatting with sales assistants to preparing speeches with course mates. It meant being part of the local area. Visiting language exchange cafes - where international and German students meet to improve their European language - was a great way to practice in a relaxed space and meet a wide range of people. Not being afraid to make mistakes is important to learn a language. By giving up that comfortable phrase " _ " (I speak only a little German), I made progress and it was praised by friends and locals alike. Germany has a lively theater scene and learning the language meant I was able to get more entertainment and an understanding of German culture. Even when it comes to eating out, knowing the language works to your advantage. In more than a few traditional German restaurants, the English menus didn't contain all the dishes listed on the German menus. Learning the language has saved me from getting on the wrong train, after last-minute platform changes were announced in German. So why... Options: A It is not popular any longer. B It costs a lot of money. C It is practical and useful. D It demands much brain to learn. Answer: C It is practical and useful. Question:

A: What is the writer's opinion about a second language?

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: When I told my father that I was moving to Des Moines , Iowa , he told me about the only time he had been there . It was in the 1930s, when he was an editor of the literary magazine of Southern Methodist University (SMU) in Dallas , Texas . He also worked as a professor at SMU , and there was a girl student in his class who suffered from a serious back disease . She couldn't afford the operation because her family was poor. Her mother ran a boarding house in Galveston , a seaside town near Houston , Texas . She was cleaning out the attic one day when she came across an old dusty manuscript . On its top page were the words , "By O. Henry". It was a nice story , and she sent it to her daughter at SMU , who showed it to my father . My father had never read the story before , but it sounded like O. Henry, and he knew that O. Henry had once lived in Houston . So it was possible that the famous author had gone to the beach and stayed in the Galveston Boarding house , and had written the story there and left the manuscript behind by accident. My father visited an O. Henry expert at Columbia University in New York , who authenticated the story as O. Henry's . My father then set out to sell it . Eventually , he found himself in Des Moines , meeting with Gardner Cowles , a top editor at the Des Moines Register . Cowles loved the story and bought it on the spot. My father took the money to the girl . It was just enough for her to have the operation she so desperately needed. My father never told me what the O. Henry story was about . But I doubt that it could have been better than his own story . Options: A O. Henry once worked in Houston. B O. Henry once stayed in Galveston. C O. Henry once moved to Des Moines. D O. Henry once taught at SMU. Answer: B O. Henry once stayed in Galveston. Question:???
