input question: Write a multi-choice question for the following article: Article: Animals Can Sense Natural Disasters Among the dead in South Asia' s tsunami were many tourists at Sri Lanka' s national wildlife park at Yala. But very few of the park's animals -- elephants, buffaloes, monkeys and wild cats -- appear to have died. There are theories that animals can sense natural disasters and run away to safety. First, it's possible that the animals may have heard the quake before the tsunami hit. The underwater burst produced sound waves known as infrasound . Humans can't hear infrasound, but many animals including dogs, elephants, tigers and pigeons can. A second early warning sign the animals might have sensed is ground vibration . The great quake would have produced vibrational waves known as Rayleigh waves. These vibrations move through the ground like waves moving on the surface of the ocean but faster. They travel at ten times the speed of sound. The Rayleigh waves would have reached Sri Lanka hours before the water hit. Mammals, birds, insects and spiders can sense Rayleigh waves. So the animals at Yala might have felt the Rayleigh waves and then run to higher ground. But what about humans? While we can't hear infrasound, we can feel it, although we don't necessarily know we're feeling it. We also experience Rayleigh waves by special sensors in our joints , which exist just for that purpose. Sadly, it seems we don't pay attention to the information when we get it. Maybe we screen it out because there's so much going on before our eyes and in our ears.???
output answer: Question: Which of the statements about "Rayleigh waves" is true?Options:A Rayleigh waves can be felt both by animals and human beings.B Rayleigh waves, just like infrasonic sound, can only be felt by animals.C Rayleigh waves are vibrational waves that usually cause quakes or tsunamis.D Rayleigh waves move on the ocean surface at a speed ten times that of sound waves.Answer:A

Write a multi-choice question for the following article: Article: Until the 1980s, the American homeless population comprised mainly older males. Today, homelessness strikes much younger part of society. In fact, a 25-city survey by the U. S. Conference of Mayors in 1987 found that families with children make up the fastest growing part of the homeless population. Many homeless children gather in inner cities; this transient and frequently frightened student population creates additional problems -- both legal and educational -- for already overburdened urban school administrators and teachers. Estimates of the number of homeless Americans range from 350,000 to three million. Likewise, estimates of the number of homeless school children vary radically. A U.S. Department of Education report, based on state estimates, states that there are 220,000 homeless school-age children, about a third of whom do not attend school on a regular basis, But the National Coalition for the Homeless estimates that there are at least two times as many homeless children, and that less than half of them attend school regularly. One part of the homeless population that is particularly difficult to count consists of the "throwaway" youths who have been cast of their homes. The Elementary School Center in New York City estimates that there are 1.5 million of them, many of whom are not counted as children because they do not stay in family shelters and tend to live by themselves on the streets. Federal law, the Stewart B. McKinney Homeless Assistance Act of 1987, includes a section that addresses the educational needs of homeless children. The educational provisions of the McKinney Act are based on the belief that all homeless children have the right to a free, appropriate education.

Problem: Given the question: Write a multi-choice question for the following article: Article: Some Chinese new-rich like eating shark fin soup because they think it shows their class. However, for the Chinese NBA idol Yao Ming, doing so is unacceptable as the practice has led to the overfishing of sharks. When Yao and his wife Ye Li got married in 2007, they publicly announced that they would not allow shark fin soup to be served at their wedding banquet. Actually, Yao had been saying no to shark fins since 2006, when he was appointed as the Goodwill Ambassador for wild life protection. Now, the 226-cm big guy is resorting to his personal influence to encourage more to say no to eating the soup and to raise awareness of animal protection. "Sharks are friends of human beings. They are not our food," Yao said. Other celebrity athletes like Olympic champions Li Ning and Kong Linghui are following on the heels of Yao, throwing themselves into serving the public as Goodwill Ambassadors for wild animal rescue. Recent reports about Yao's retirement have saddened tens of thousands of basketball fans both at home and abroad. Yet Yao's influence goes far beyond the basketball courts. Yao has engaged himself in charity and public welfare services for quite a while. When the devastating 8.0-magnitude earthquake hit Wenchuan in southwest China in 2008, Yao donated 2 million yuan . "When I was a little boy, my parents and teachers told me to help others and to be a good man," Yao recalled. "But I could not donate then because I had not much pocket money. After I moved to Houston, I got involved in quite a number of community service activities and I felt a strong sense of achievement when I got people together," Yao said. Like Yao, newly crowned French Open champion Li Na has showed her willingness to donate. Li gave 480,000 yuan of her prize money from the open, plus 20,000 yuan from her own pocket, to a local nursing home in her hometown. Another Chinese sports icon, hurdler Liu Xiang, has also been actively involved in charity for years.
