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.

Let me give you an 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.

Article: In 1982 Steven Callahan was crossing the Atlantic alone in his sailboat when it struck something and sank. He was out of the shipping lanes and floating in a life raft, alone. His supplies were few. His chances were small. Yet when three fishermen found him seventy-six days later, he was alive. His account of how he survived is fascinating. But the thing that caught my eye was how he managed to keep himself going when all hope seemed lost. Giving up would have seemed the only wise option. When people survive these kinds of circumstances, they do something with their minds that gives them the courage to keep going. Many people in similarly desperate circumstances give in or go mad. "I tell myself I can handle it," wrote Callahan. "Compared to what others have been through, I'm fortunate. I tell myself these things over and over, building up fortitude...." It struck me as something important. And I've told myself the same thing when my own goals seemed far off or when my problems seemed too overwhelming. And every time I've said it, I have always come back to my senses. The truth is, our circumstances are only bad compared to something better. But others have been through much worse. So here, coming to us from the extreme edge of survival, are words that can give us strength. Whatever you're going through, tell yourself you can handle it. Tell this to yourself over and over, and it will help you get through the rough spots.
