In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Example Input: Article: Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger , but we also affect our water supply in less obvious ways. You may wonder how paving a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave the less water can flow into the ground to become groundwater. Human activity is not responsible for all water shortages . Drier climates are of course more likely to have droughts than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs. Thinking about the way we use water every day can make a big difference, too In the United States , a family of four can use 1. 5 tons of water a day! This shows how much we depend on water to live, but there's a lot we can do to lower the number. You can take steps to save water in your home. To start with use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher only when it is full . Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
Answer: Throwing rubbish into lakes.
Example Output: Which of the following is most likely to lead to less groundwater?

Example Input: Article: My 11-year-old son and I rides bikes to and from his school every day. I accompany him on the 20-minute ride through Manhattan, drop him off and return at the end of day to pick him up. We always ride together; sometimes he leads; sometimes I do. And as we ride, we communicate the ways to minimize the dangers: Don't go too fast, and watch out for doors suddenly swinging out from parked cars and jaywalking pedestrians, etc. Some friends worry about the risk of riding in traffic, but is there a better way to let my son know how to deal with traffic dangers? But recently he requested me to start hanging back a half block or so. This way he could enjoy the feeling of riding on his own, with the security of knowing that I was nearby in case he needed me. This is healthy, of course, as my son needs space to develop independence in preparation for his inevitable (,) departure from home. However, that means soon he will want to ride to school on his own, and I will no longer have this wonderful routine. "Let your children go if you want to keep them." I understand this and am trying to let my son go in age-appropriate phases, but I still suffer. It's one of the most troubling experiences of parenthood -- recognizing that your presence is becoming less welcome. My dilemma as a husband mirrors the concern I feel as a parent. My wife has just left on a six-month mission to cover the situation in Libya. In the days leading up to her departure, we spoke openly about the possibility, however unlikely, that she might be killed. But while I influence her decisions, I do not control them. Finally, it was her decision. I know that letting go is the wisest path in this case too. As we travel through life's phases, we must let go of so much. And I don't think it gets easier with practice. But maybe just accepting that eventually we will have to let go is the secret to living a full life.
Answer: To teach his son to ride in traffic.
Example Output: Why does the writer accompany his son on his daily ride to school?

Example Input: Article: My father woke me up early one summer morning when I was fourteen and announced: "Get up. You're going with me to cut grass." The idea that my father thought I was old enough to help him in his business made me feel proud and excited. From sunup to sundown, my father, my younger brother and I worked in the large yards in a rich part of Atlanta, Georgia. By the end of the day I was tired out, but I felt good. I had put in a hard day's labor and had earned $ 6 One day my father found some leaves I'd missed and pulled me aside. "Clear away these leaves!" he said firmly, "and don't make me have to do it again." The message was clear. Today I value the importance of doing a job right the first time. It will never fail to impress the person you are working for. After two years, my father told me and my brother that he felt we were old enough to do lawns on our own. Every Saturday during our last two years of high school, we set out early in the morning with the same desire and drive we had gained while working under our father. Taking care of lawns was not exciting or high-paying, but that didn't matter. It taught me that any job was a good job and that whatever I was paid was more than I had before. A newspaper reporter once asked me how someone could possibly live on a forty-hour-a-week minimum pay. "My father has never worked just forty hours a week, and neither have I," I replied. "If you're only working forty hours, you probably don't want to do any better than you are doing." In every job I've held from doing lawns to washing dishes, I have learned something that helped me in my next job. If you work hard enough, you can learn from any job you do.
Answer: He was old enough to help his father.
