Teacher: In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Article: There are a lot of public libraries in Britain. These libraries have more than one hundred and fifteen million books, not including those libraries of public schools. Public libraries not only lend books, music records but also help children, patients in hospitals and others to get special play readings, film shows and so on. The first public libraries were founded in about the year 1850. Today's public libraries usually have a reading-room, a lending room and a reference room. The greatest and most famous library in Britain is that of the British Library in London. It was founded in 1973 and has over 10, 000, 000 books. It has nearly every magazine, newspaper and book published in Britain and other parts across the world.
Answer: 10,000,000 or less.
Solution: How many books are there in the British Library?
Reason: In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.

Now, solve this instance: 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.
Answer: Because the animals might have picked up the danger signals and ran away.
Student:
Why did few animals at Yala die when the tsunamis that caused a huge number of human deaths hit?
