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: 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.

My mom suggested that I organize a food drive in our development and donate what I collected to a local shelter.Anything that would help finish the project seemed like a good idea, so I agreed.I made up flyers asking for donations and placed flyers at every house in my neighborhood. I was getting ready to fetch the cans from my neighbor's yards on the day of the food drive when all of a sudden it started to pour.Rain flooded the roads and wind blew hard, but I was determined to complete my task.My mom drove me around our development and I jumped out at every house to collect items people had put out. When we finally arrived the shelter, I was a little nervous because I had never been there before.The woman in charge was extremely grateful for the donations and said that the world would be ganizing the food drive and delighted that my service to the community would make a difference in people's lives. As I was leaving the shelter, a man asked if I was the one who had brought all the food.I shyly nodded, and he said, "A round here, you are a hero." From that point on, I made myself a promise that I would serve the community more often, even when it was not required.Through this school assignment, I have realized that caring for others is an important part of living and the world would be a completely different place if people all help those who are less fortunate.
