Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: It is common sense that children who walk or cycle to school have a lower risk of obesity than those by car. But driving your youngsters to the gates could also cause their academic work to suffer. Researchers found children who were driven to school, or who took public transport, had poorer concentration levels than those who took a more active route such as walking or cycling. The joint study by researchers at two Danish universities found the regular exercise could advance a student up to half a year in their studies. Children who were driven to school, or who took public transport, performed less well in a test measuring concentration levels, than those who had walked or cycled. The results surprised the researchers, as their hypothesis originally focused on the effects of eating breakfast and lunch on pupils' ability to concentrate. "The exercise one uses to transport oneself to school is reflected in the level of concentration one has about four hours later," Niels Egelund, a co- author of the report said. "The results showed that having breakfast and lunch has an impact, but not very much compared to having exercise." "As a third-grade pupil, if you exercise and bike to school, your ability to concentrate increases to the equivalent of someone half a year further in their studies," he added. In the survey, taken by 19, 527 pupils aged five to 19 years old, participants were asked about their exercise habits and were then given a basic test measuring their concentration. "Most people know the feeling of being refreshed after having exercised, but it is surprising that the effect lasts for so long," Egelund said. Previous research from the university of Montreal has found that exercise helps our brains make better use of oxygen. It may also reduce mental fatigue and sharpen your thinking in between gym sessions. And last week Swedish researchers said they found that muscular boys will live longer than their weaker friends. And even if they are overweight by the time they get to adulthood, those with... Options: A Exercise helps our brain make the most of oxygen. B Exercise can improve the level of concentration. C Exercise can make you sharp- minded. D Exercise can decrease mental fatigue. Answer: B Exercise can improve the level of concentration. Question:

A: Which of the following is NOT the result of the research from the University of Montreal?

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Most people think that the capital of the movie world is Hollyhood, in the United States. However, the real movie capital is Mumbai, in India. Mumbai used to be known as Bombay, and so the film industry there is called "Bollywood." Bollywood makes twice as many movies each year as Hollyhood--more than 800 films a year. The movies from Bollywood are very different from Hollywood movies. For one thing, Bollywood movies are much longer than most Hollywood movies. Most Bollywood movies are more than three hours long, and contain singing, dancing, action, adventure, mystery, and romance (but usually no kissing). Because Bollywood films contain so many different features, this style of film is sometimes called a "masala" film. ("Masala" is an Indian word for a mixture of spices.) Another big difference between Bollywood and Hollywood movies is the way movies are made. It takes much longer to make a movie in Hollywood than in Bollywood. In fact, filming may begin on a Bollywood movie before the script even finished. The director and writers can make up the story while the film is being made. Sometimes they will even write the script by hand instead of taking time to type it. Bollywood actors are very popular and some are in such high demand that they may work on several movies at the same time. They may even shoot scenes for several films on the same day using the same costumes and scenery. Since most Bollywood movies follow the same kind of story, shooting scenes for several films at the same time is not a big problem for actors or directors. This also helps keep the cost of Bollywood movies lower than the cost of Hollywood movies. The average Bollywood film, with a budget of only two million U.S. dollars, seems very cheap compared to the average budget of sixty million U.S. dollars for a Hollywood film--thirty times as much! Options: A They have spicy stories. B They show Indian culture. C They are much longer than Hollywood films. D They mix different styles of movies. Answer: D They mix different styles of movies. Question:

A: Why are Bollywood films often called "masala" films?

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: There is one word that is on the lips of Americans , day and night , "Sorry". One time as I was walking on the street , a young man ran by hurriedly , brushing against my handbag . Even as he continued on his way , he turned back and said "sorry" to me . Even in a rush , he didn't forget to apologize . One day , after I bought some apples , the salesman was giving me the change , but I wasn't ready for it , and a coin dropped on the ground, "I'm sorry ," he said while bending down to pick it up . I was puzzled --why would he apologize when it was my fault ? Another time , I stepped on a man's foot in an escalator . At the same time , we both said "sorry" . I thought it interesting : was it really necessary for him apologize ? Later on , an American friend explained to me that according to the American ideas, the escalator is public place which everyone should be able to stand in . After someone occupies a position in the escalator , making it difficult for someone else to find a place to stand in , isn't it necessary to express an apology ? During my stay in America , I gradually realized that when friction occurs in daily life , Americans don't care much about who is responsible . If someone is troubled , a "sorry" is always necessary . Even if the other person is hurt , the "sorry" would cool tempers . Perhaps this is why I never saw anyone quarreling on the buses , subways or streets in America . Options: A the escalator is a public place B the man was very afraid of me C the "sorry" said to me was for everyone D there wasn't enough room to get my feet in Answer: A the escalator is a public place Question:

A:
The man on whose feet I stepped apologized to me because _ .
