In this task, you're given an article and an answer. Your task is to generate the fill-in-the-blank question for this answer based on the given article. The blanks are always at the end of the question, and can be filled with more than one word or phrase.
One example is below.
Q: Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.
Answer: whether mood affects their learning ability
A: Researchers did experiments on kids in order to find out _ .
Rationale: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment.
Q: Article: A dog's tail can tell you a lot more than you might think. Is it wagging to the left or is it wagging to the right? "The direction of tail wagging does in fact matter,"said Giorgio Vallortigara,a professor at the University of Trento in Italy. Professor Vallortigara finds that the way the tail is wagging can tell you a lot about a dog's state of mind--whether you're a human or another dog. What's the difference between a left wag and a right wag?Professor Vallortigara and his colleagues have studied 43 dogs of various breeds -- German Shepherds,Beagles,Boxers,Border Collies and some mutts. They find that if a dog wags its tail to the left. it's feeling anxious or nervous. The reason could be an unfamiliar or dangerous situation,an unfamiliar person,or an unfamiliar and possibly threatening dog. But if the tail is wagging to the right,it means the dog is feeling relaxed and approachable. "The tail is a very important signal,"said Thomas Reimchen,a biologist at the University of Victoria in British Columbia, Canada. "There is a lot of visual information that dogs use when communicating with each other. " How did the scientists figure all this information out? They had the dogs in their study watch videotapes of other dogs. When the dog on the tape wagged its tail to the right,they say the other dogs remained calm and cool. But when the dog on the tape wagged its tail to the left,the other dogs got anxious. The researchers are still not exactly sure if the direction of tail wagging is something the dog does consciously. They suspect that it might be something the dog does without even thinking about it -- kind of like when you get goose bumps if something scares or startles you. They plan to do more research to get more information about what dogs are thinking and feeling while they're wagging. As Reimchen said,"I'm not going to be surprised if we find all sorts of really interesting processes that nobody has ever seen before. "
