Question: Write a multi-choice question for the following article: Article: Wind is the great maker of waves. There are exceptions , such as the tidal waves sometimes caused by earthquakes under the sea. But the waves most of us know are caused by winds blowing over the sea . Now let's learn some physical things about it. A wave has height, from low point to high point . It has length --the distance from this high point to that of the following wave. The period of the wave means the time it takes for succeeding high points to pass a fixed point. None of these things stays the same--for all depend upon the wind, upon the depth of the water and many other matters. The water that makes up a wave does not advance with it across the sea. Each drop of water turns around in a little circle with the passing of the wave, but returns very nearly to its original position . And it is lucky that this is so. For if the huge groups of water that make up a wave really moved across the sea, sailing would be impossible. If we want to find the speed of a wave, we may use the following way : Speed =" wavelength" x frequency . Here, wavelength is the distance between two high points , frequency means the number of cycles per second
Answer: Question: What causes waves?Options:A Earthquakes and nothing else.B Only wind.C Wind causes most waves.D Wind causes some waves.Answer:C

[Q]: Write a multi-choice question for the following article: Article: Have you ever dreamed about sending a letter to yourself or your friends in the future? While express mail is a fast way to send your letters, there is another type of mail appearing in China as a new business--future mail. "The letter should be sent next Mother's Day and not a day earlier!" Lin Xiaofan, a college student in Shanghai, tells one of the companies offering the service. Lin Xiaofan wrote the letter to her mother nearly a year earlier to express her love to her mother for next Mother's Day. "Offering this service makes people slow down and lets them understand the meaning of 'time' in another way," said Zheng Zhimin, manager at a "future mail" company. Zheng thinks "future mail" letters help remind us of care, friendship and love. While "future mail" is becoming more and more popular, some people are wondering what will happen if the postal address changes or if the company goes broken before the letters arrive. Zheng said customers are glad to sign a contract to make sure that they can be _ if their letters are lost or damaged. Most of the customers are college students and young white-collar workers. Psychologists said that young Chinese might have a new way to express their feelings through this service. Most people put their hopes and wishes in the letter so that they can experience the connection between the past and the present when they receive the letter.

Parents hope computers can help their children improve their study at school. But many of their children use computers to play games and watch videos instead of studying. We often see that computer net bars are crowded with people, especially young boys. They spend a lot of money competing with the computerized machines. The more they lose, the more they want to win. The result is that they don't want to work or study. In some countries, even scientists hate computers. They say computers cause millions of people to lose their jobs or cause them a lot of trouble. Computer game addiction is a serious problem in social life. Something has to be done to solve the problem.

Please answer this: Write a multi-choice question for the following article: Article: Health officials in Canada are very busy these days. They are placing chickens at fixed points all along their 2,500 km border with the United States of America. It's not a joke, nor have the Canadians gone mad. They are using these chickens to see if the West Nile virus is still around. The virus infects birds, so the chickens have a chance of catching the virus and fall ill. The West Nile virus is spread among humans. It killed seven people in New York last year. Countries around the world are realizing that it may just be possible to stop certain kinds of people from entering their land. However, it is very difficult to stop viruses traveling from one end of the earth to another. When they travel to new places, they get used to the environment very easily and sometimes start destroying the local plant and animal life. These biological polluters are called smart polluters. These smart polluters can be carried across borders of countries unknowingly. Just as we humans are travelling across the world more often than earlier, these biological polluters have also started journey much more. They slide into airplanes through their wheels. They dig into objects that travelers may be carrying from one country to another. There are some good examples of how these polluters work. The water hyacinth of South America is blocking lakes in China and Africa. Tree snakes from Papua New Guinea are busy eating up some birds in the country of Guam, which breaks its natural balance. That's why the customs officials in many foreign countries prevent people from bringing in a small plant, or an object made of wood that is in its natural form. The customs officials have these rules because these varieties of plants are special to certain places. The plants have the power to spread new illnesses among native plants and animals. Biological polluters always create problems in places where they do not belong. They could be special varieties of plants, bugs or even animals.
