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.
Example: 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.

The Arabs say that camels are so acutely aware of injustice and ill-treatment that a camel owner who punishes one of the beasts too hard finds it difficult to escape the camel's revenge .Apparently, the animal will remember an injury and wait for an opportunity to get revenge. In order to protect themselves from the vengeful beasts, Arabian camel drivers have learned to trick their camels into believing they have achieved revenge. When an Arab realizes that he has excited a camel's rage, he places his own garments on the ground in the animal's path. He arranges the clothing so that it appears to cover a man's body. When the camel recognizes its master's clothing on the ground, it seizes the pile with its teeth, shakes the garments angrily and steps on them in a rage again and again. In the end, after its rage has died away, the camel leaves, believing its revenge is completed. Only then does the owner of the garments comes out of hiding, safe for the time being, thanks to this clever trick.
