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: The first memory I have of him---of anything, really---is his strength. It was in the late afternoon in a house under construction near ours. The unfinished wood floor had large, terrifying holes whose big and opening darkness I knew led to nowhere good. His powerful hands, then age 33, wrapped all the way around my tiny arms, then age 4, and easily swung me up to his shoulders to command all I surveyed. The relationship between a son and his father changes over time. It may grow and flourish in mutual maturity. It may sour in hated dependence or independence. With many children living in single-parent homes today, it may not even exist. But to a little boy right after World War II, a father seemed a god with strange strengths and strange powers enabling him to do and know things that no mortal could do or know. Amazing things, like putting a bicycle chain back on, just like that, or building a hamster cage, or guiding a jigsaw so it forms the letter F; I learned the alphabet that way in those pre-television days. There were, of course, rules to learn. First came the handshake, a good firm squeeze accompanied by an equally strong gaze into the other's eyes. "The first thing anyone knows about you is your handshake," he would say. And we'd practice it each night on his return from work, the serious toddler in the old Cleveland Indian's cap running up to the giant father to shake hands again and again until it was firm enough. One day, I realize now, there was a change. I wasn't trying to please him so much as I was trying to impress him. I never asked him to come to my football games. He had a high-pressure career, and it meant driving through most of Friday night. But for all the big games, when I looked over at the sideline, there was that familiar fedora . And by God, did the opposing team captain ever get a firm handshake and a gaze he would remember? Then, a school fact contradicted something he said. Impossible that he could be wrong, but there it was in the book. These accumulated over time, along with personal experiences, to strengthen my own developing sense of values. And I could tell we had each taken our own, perfectly normal paths. I began to see, too, his blind spots, his prejudices and his weaknesses. I never threw these up at him. He hadn't to me, and, anyway, he seemed to need protection. I stopped asking his advice; the experiences he drew from no longer seemed relevant to the decisions I had to make. He volunteered advice for a while. But then, in more recent years, politics and issues gave way to talk of empty errands and, always, to illness. After much thought and practice " You can do whatever you have to do.", one night last winter, I sat down by his bed and remembered for an instant those terrifying dark holes in another house 35 years before. I told my father how much I loved him. I described all the things people were doing for him. But, I said, he kept eating poorly, hiding in his room and violating the doctor's orders. No amount of love could make someone else care about life, I said; it was a two-way street. He wasn't doing his best. The decision was his. He said he knew how hard my words had been to say and how proud he was of me. "I had the best teacher," I said. "You can do whatever you have to do." He smiled a little. And we shook hands, firmly, for the last time. Several days later, at about 4 A.M., my mother heard Dad shuffling about their dark room. " I have some things I have to do," he said. He paid a bundle of bills. He composed for my mother a long list of legal and financial what-to-do's " in case of emergency." And he wrote me a note. Then he walked back to his bed and laid himself down. He went to sleep, naturally. And he did not wake up.
