input question: Write a multi-choice question for the following article: Article: In cities with rent control, the city government sets the maximum rent that a landlord can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartment. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that after a long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rent-controlled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city. Some experts argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low-paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics hold the opinion that an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage. Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages. Economic theory predicts the results of economic decision, such as decisions about farm production, rent control, and the minimum wage. The predictions may be corrected only if "other things are equal". Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree,...???

Write a multi-choice question for the following article: Article: If a noisy neighbor is blasting music at all hours of the day and night, drowning out your phone conversations and interrupting your sleep, you can call the police. But what is a whale to do? Natural noise from waves, wind, rain and even earthquakes is common in oceans. Unfortunately, man-made noise from oil and gas drilling, sonar, and ships is also present. Low frequency noise has doubled off the California coast every decade since the nineteen sixties. The main reasons are ships' propellers . They not only generate continuous low frequency sound, some propellers cavitate , which means they create air bubbles that collapse, creating loud popping sounds. Whales use low frequency calls to communicate across thousands of miles of ocean. They are threatened by noise pollution because it can prevent them from contacting each other and from locating their foods. Endangered humpback and right whales, which use fibrous baleen to strain food from the water, are the most at risk. Scientists studying right whales off Canada's east coast have discovered that whales are sending louder calls through the water to make themselves heard. Because they invest more energy in making calls, they have less energy available for finding food and mating. Other scientists measuring whale calls against background noise pollution have discovered that right whales have lost about eighty percent of their normal communication area. This could seriously affect survival of this already threatened species. Scientists don't have badges and guns, but they are trying to correct the noise pollution problem. By tracking ships and marine mammals and understanding how noise travels, they are creating sound maps. They hope to get shipping lanes moved so that the noise pollution ships create will not overlap with areas most important to the whales.

Q: Write a multi-choice question for the following article: Article: Scientific discoveries have changed man's life a great deal during the past century. First of all, they have greatly improved material well-being in several areas of life. In the field of medicine, cures for life threatening diseases have enabled people to live longer. In communication, the telephone and e-mail have made it possible for us to communicate with anyone in the world without leaving our homes or offices. Advances in transportation allow businessmen to fly across the ocean in the morning and return home the same evening. Space technology has put men on the moon. More efficient ways of using available resources, such as coal and solar power, have been explored. Scientific discoveries have also changed man's moral atmosphere. Ethical issues are raised by these discoveries. Should we keep a terminally ill person alive through drugs and machines or should we allow him to die in dignity? With advances in transportation had come the problem of pollution for nearly every major city in the world. If cities become uninhabitable, then such technical advances may come with too great a price to pay. Many people also question the wisdom of sending men to the moon when there are urgent problems that have not been solved on earth. During future years, increasing attention must be given to the moral as well as the practical applications of science.
A: Question: The best title for the passage is _ .Options:A Science discoveriesB Science and daily lifeC Advances in transportationD City pollutionAnswer:B

Problem: Given the question: Write a multi-choice question for the following article: Article: Coral Polge is a person who has provided comfort to thousands. She has a remarkable talent which may prove the survival of the human spirit after death, for Coral is a medium who draws the portraits of spirits who contact her. Coral, whose parents were spiritualists, was brought up in Harrow, North London, where she attended a local spiritualist church. She studied art at the local college, where she specialized in textile design. Even though, at the time, she wasn't very good at drawing portraits, she met a medium who told her she would be a psychic artist. She doesn't actually see the dead nor are her hands controlled by the spirits; instead she 'feels' them coming through. Early in her career she drew the portraits of 'spirit guides' from whom she had received help. These portraits of guides, who included Red Indians, nuns and monks, were remarkable, yet could have been attributed to the working of a strong imagination. She also drew portraits by holding on to letters that had been written by people who had since died. Coral says, 'I know exactly what to draw without thinking about it. It's involuntary, like breathing or walking.' Not only are her portraits a good likeness but she sketches her subjects in clothes they would have worn in life. Coral has displayed her talent at public meetings around the world. At one gathering there was a woman whose grandfather had just died. Her name was Phyllis Timms. Coral made a sketch of a man who had a long moustache and Phyllis recognized the man as her grandfather. However, she was reluctant to acknowledge the portrait without extra proof. Coral then said that the colour green was a link with the man whom she had drawn. Mrs Timms, whose maiden name had been Green, understood the significance of the comment and claimed the portrait. There are some people for whom this is evidence of survival from beyond the grave. Others, who have their reservations, may put it down to an extraordinary kind of extrasensory perception . Whatever...
