Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Hacking our senses to boost learning power Some schools are pumping music, noises and pleasant smells into the classroom to see if it improves exam results. Could it work? Why do songs stick in our heads? What does your school smell like? Is it noisy or peaceful? It might not seem important, but a growing body of research suggests that smells and sounds can have an impact on learning, performance and creativity. Indeed, some head teachers have recently taken to broadcasting noises and pumping smells into their schools to see whether it can boost grades. Is there anything in it? And if so, what are the implications for the way we work and study? There is certainly some well-established research to suggest that some noises can have a harmful effect on learning. Numerous studies over the past 15 years have found that children attending schools under the flight paths of large airports fall behind in their exam results. Bridget Shield, a professor of acoustics at London South Bank University, and Julie Dockrell, from the Institute of Education, have been conducting studies on the effects of all sorts of noises, such as traffic and sirens , as well as noise generated by the children themselves. When they recreated those particular sounds in an experimental setting while children completed various learning tasks, they found a significant negative effect on exam scores. "Everything points to a bad impact of the noise on children's performance, in numeracy, in literacy, and in spelling," says Shield. The noise seemed to have an especially harmful effect on children with special needs. Whether background sounds are beneficial or not seems to depend on what kind of noise it is -- and the volume. In a series of studies published last year, Ravi Mehta from the College of Business at Illinois and his colleagues tested people's creativity while exposed to a soundtrack made up of background noises -- such as coffee-shop chatter and construction-site drilling -- at different volumes. They found that people were more... Options: A students' creativity improves in a quiet environment B we may play some Mozart music while students are learning C a proper volume of background noises does improve creativity D noise of coffee-shop chatter is better than that of construction-site drilling Answer: C a proper volume of background noises does improve creativity Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Five people are at our table, including myself. I've already learnt a great deal about them in the short time we've been at sea, although we rarely meet except at mealtimes. First of all, there is Dr. Stone. He is a man of about sixty-five, with gray hair and a friendly face. He gave up his work a short while ago and is now traveling round the world before he retires to some quite country village. As a young man, he served for many years as a doctor in the army and visited many countries. He's told us a great deal about the city to which they are going. Then there is "Grandmother". I call her that because her name escapes me. In spite of being a grandmother, she looks remarkable young, no more than fifty. She is on her way to visit a daughter who went to Australia some years ago. Naturally she is very excited at the thought of seeing her again, and her three grandchildren, whom she has never seen. Then there is a man I don't care for very much, the engineer by the name of Barlow. He has been _ in England and is now returning to his work in Singapore. The other person who sits at our table is Mrs. Hunt. I've found out hardly anything about her. She's extremely quiet and rarely talks, except to consult the doctor about children's various illnesses. She is on her way to join her husband in India. Options: A She looks old. B he respects her C She has three daughters D he can't think of her name Answer: D he can't think of her name Question:

The answer is:
The writer calls the second person "Grandmother" because _ .

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Bananas are one of the world' s most important food crops. They are also one of the most valuable exports. Bananas do not grow from seeds. Instead, they grow from existing plants. Bananas are threatened by disease because all the plants on a farm are copies of each other. They all share the same genetic weaknesses. For example, the Cavendish banana is most popular in North American and European markets. However,some kinds of fungus organisms easily infect the Cavendish. Black Sigatoka disease affects the leaves of Cavendish banana plants. The disease is controlled on large farms by putting chemicals on the plant' s leaves. Farmers put anti-fungal chemicals on their crops up to once a week. Another fungal disease is more serious. Panama disease attacks the roots of the banana plant. There is no chemical treatment for this disease. Infected plants must be destroyed. Panama disease has affected crops in Southeast Asia, Australia and South Africa. There is concern that it may spread to bananas grown in the Americas. This could threaten an important export product for Central and South America. The International Network for the Improvement of Banana and Plantain supports research on bananas. The group has headquarters in France and other offices in the major banana-growing areas of the world. The group says that more research must be done to develop improved kinds of bananas. The group says that fungal diseases mainly affect only one kind of banana. In fact, there are five hundred different kinds of bananas. Food and Agriculture Organization of the United Nations has said that the Cavendish banana represents only 10% of world production. The U.N. agency says farmers should grow different kinds of bananas. This protects against diseases that affect only one kind. Experts warn that disease may cause the Cavendish banana to disappear. This happened earlier to another popular banana because of its genetic weakness against disease. Options: A The Cavendish banana can mainly be imported from North America and Europe. B Panama disease affects the leaves of Cavendish banana plants. C The Cavendish banana won't die out in the future. D The Cavendish banana makes up only one tenth of world production. Answer: D The Cavendish banana makes up only one tenth of world production. Question:
