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: A messy desk can actually lead people towards clearer thinking, say researchers from Germany. The researchers found in a series of linked studies - using a messy desk and a messy shop front - that people actually thought more clearly when all around was chaos, as they sought to simplify the tasks at hand. Visual and mental clutter forces human beings to focus and think more clearly. Famous thinkers and writers such as Albert Einstein and Roald Dahl have been notorious for their untidy desks. "Messy desks may not be as detrimental as they appear to be, as the problem-solving approaches they seem to cause can improve work efficiency or increase employees' creativity in problem solving," say the authors. "Business and government managers often promote 'clean desk' policies to avoid disorganized offices and messy desks, for the purpose of boosting work efficiency and productivity," writes lead researcher Jia Liu of the University of Groningen in a paper published in the Journal of Consumer Research. "This practice is based on the conventional wisdom that a disorganized and messy environment can clutter one's mind and complicate one's judgments." "However, not all evidence supports this conventional link between a messy environment and a messy mind." The scientists tested people's response in various 'messy' environments - including a messy shop front, a disorganized desk, and even a work environment where a language task 'reminded' people of messiness. The authors found in the series of six studies people tended towards simplicity in their thinking. "They categorized products in a simpler manner, were willing to pay more for a T-shirt that shows a simple-looking picture, and sought less variety in their choices." said the researchers.
Answer: to support the idea that clearer thinking comes from messy environment.
Example Output: Why does the author take Albert Einstein as an example?

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?
