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: Sitting in the play area of the doctor's office, my children, Paul, four, and Bailey, three, built a Lego tower while we waited to be called for Paul's examination. "Good job, you guys,"I said, trying not to sound too tired. My husband was away on business, and it was difficult being alone with the kids. At times I felt like I was living in the jungle rather than the suburbs. "Don't put the Lego in your mouth, Bailey,"I said. Paul grabbed it from him."That's not nice, Paul,"I said. He gave back the Lego. I looked around the waiting room. A woman was eating something, a couple were talking, and an old gentleman in a blue jacket was reading a magazine. I wished I could sit quietly for a while. I wanted to be able to take a rest, or go shopping alone. At once, I was ashamed of myself. What kind of mother was I? "God,"I thought, "help me to be the very best mom I can be." The nurse came into the waiting room to get us. Just at that moment, the old gentleman in the waiting room put down his magazine and came up to me. With a smile on his face, he said, "Your children are most certainly lucky to have such a wonderful mother.""Thank you,"I replied in a low voice and watched him walk back to his seat. We followed the nurse into the examination room. While she weighed Paul, I told her how that man had made my day. Motherhood is still a jungle sometimes, but now when I feel tired I remember the encouraging words of the old gentleman.
