input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: What are American high schools like? Well, I'm happy to tell you what I know. When I started school here, it had already been a week since the school opened. At this school, freshmen usually go on a trip for about three days at the beginning of school. Unfortunately I missed that wonderful trip, which would have been the best time to get to know my classmates. I was really sad. I wished I'd known about it earlier. Despite the disappointment, however, I gradually adapted to my new life and school. There is a space in the basement of the teaching building where students chat and meet each other. As we do not always have the same classrooms and classmates, the school wants us to get to know each other there. Students usually come to school early, sit in that space and have fun. Around the space, there are many lockers for students to leave their books in, so that students do not have to carry a heavy schoolbag everywhere. It really surprises me that we have almost no textbooks. We only have textbooks for World History and Algebra 2 and they are big and heavy, like bricks. For other classes, we only need binders with paper in them. Without textbooks, students learn things freely and actively. For example, my humanities teacher just teaches us what is in her mind at the time. We never know what we will learn. Another difference between American schools and Chinese schools is that American schools care about students' morality more than their academic studies. For example, if you do not finish your homework, you will just be asked to do it later, but if you cheat or lie, you will get a warning or even be kicked out. I think that most students here are good at schoolwork as well, but compared to Chinese students, they can make learning a more joyful experience. I think we should take the good points from our two different kinds of education to perfect our approach to studying. Options: A He was late for school. B He missed the trip at the beginning of school. C He didn't know anyone. D American students looked down upon him. Answer: B He missed the trip at the beginning of school. Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: ADDIS ABABA, Ethiopia - One of the world's most famous fossils - the 3.2 million-year-old Lucy skeleton unearthed in Ethiopia in 1974 - will go on an exhibition tour abroad for the first time in the United States, officials said Tuesday. Even the Ethiopian public has only seen Lucy twice. The Lucy on exhibition at the Ethiopian National Museum in the capital, Addis Ababa, is _ while the real remains are usually locked in a secret storeroom. A team from the Museum of National Science in Houston, Texas, spent four years discussing with the Ethiopians for the U.S. tour, which will start in Houston next September. "Ethiopia's rich culture of both the past and today, is one of the best kept secrets in the world," said Joel Bartsch, director of the Houston museum. The six-year tour will also go to Washington, New York, Denver and Chicago. Officials said six other U.S. cities may be on the tour. But they said plans had not been worked out. Travelling with Lucy will be 190 other fossils. Lucy, her name taken from a Beatles song that played in a camp the night of her discovery, is part of the skeleton of what was once a 3-foot-tall ape-man . Options: A introduce a few U.S. museums B describe some research work C discuss the value of an ape-man D report a coming event Answer: D report a coming event Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: You are watching a film in which two men are having a fight. They hit one another hard. At the start they only fight with their fists .But soon they begin hitting one another over the heads with chairs. And so it goes on until one of the men crashes through a window and falls thirty feet to the ground below. He is dead! Of course he isn't really dead. With any luck he isn't even hurt. Why ? Because the men who fall out of high windows or jump from fast moving trains, who crash cars of even catching fire, are professionals .They do this for a living. These men are called stuntmen. That is to say, they perform tricks . There are two sides to their work. They actually do most of the things you see on the screen. For example, they fall from a high building. However, they do not fall on to hard ground but on to empty cardboard boxes covered with a mattress . Again, when they hit one another with chairs, the chairs are made of soft wood and when they crash through windows, the glass is made of sugar! But although their work depend on trick of this sort, it also requires a high degree of skill and training. Often a stuntman's success depends on careful timing .For example, when he is "blown up" in a battle scene, he has to jump out of the way of the explosion just at the right moment. Naturally stuntmen are well paid for their work, but they lead dangerous lives. They often get seriously injured, and sometimes killed. A Norwegian stuntman, for example, skied over the edge of a cliff a thousand feet high. His parachute failed to open, and he was killed. In spite of all the risks, this is no longer a profession for men only. Men no longer dress up as women when actresses have to perform some dangerous action. For nowadays there are stuntgirls too! Options: A Strength B Exactness C Speed D Carefulness Answer: B Exactness Question:

A: Which of the following is the main factor of a successful performance?

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Children today spend less time outdoors than ever before and it may be harmful not only to their physical health, but also to their cognitive development. A year-long study, recently published in the Sciences, found that elementary school children who were exposed to more green space within or directly outside their school showed improved learning and memory. The findings reinforce that of a recent six-year study on 905 Massachusetts public elementary schools, which found that students in schools that had more "greenness" in their surroundings reported higher scores on standardized testing in English and math. "There is an expanding body of scientific evidence linking the human experience in the natural world to better physical and mental health and improved cognitive abilities," journalist Richard Louv, co-founder of the Children & Nature Network, said in an email to The Huffington Post. "An increasing number of homeschoolers, nature preschools, independent primary and secondary schools, and forward-thinking public schools are incorporating nature experience into learning." The new study was conducted on more than 2,500 children in second, third and fourth grade at 36 primary schools in Barcelona, Spain. Researchers found that the students who attended schools with more green space showed a 5 percent improvement in the short-term memory that's critical for reasoning, learning and comprehension. But their inattentiveness decreased slightly. Spending time outside could have a number of benefits for children beyond improved memory and attention. Another recent study found that adventurous outdoor play such as climbing, rough and tumble play, and exploring alone improves children's physical health while also help them develop creativity and social skills greatly. Some schools are starting to take notice, creating more space for children to enjoy being in nature, including community gardens, outdoor playgrounds and small parks. Options: A The cognitive abilities of children today decreased. B The findings of another six-year study were incorrect. C Being exposed to nature was beneficial to the learning of pupils. D Students had higher scores on testing in English and math than before. Answer: C Being exposed to nature was beneficial to the learning of pupils. Question:???
