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: Article: There are a lot of public libraries in Britain. These libraries have more than one hundred and fifteen million books, not including those libraries of public schools. Public libraries not only lend books, music records but also help children, patients in hospitals and others to get special play readings, film shows and so on. The first public libraries were founded in about the year 1850. Today's public libraries usually have a reading-room, a lending room and a reference room. The greatest and most famous library in Britain is that of the British Library in London. It was founded in 1973 and has over 10, 000, 000 books. It has nearly every magazine, newspaper and book published in Britain and other parts across the world.
Answer: 10,000,000 or less.
Example solution: How many books are there in the British Library?
Example explanation: In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.

Problem: 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.
Solution: Why does the author take Albert Einstein as an example?
