Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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.
Solution: How many books are there in the British Library?
Reason: In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.

Now, solve this instance: Article: New evidence shows that getting enough Vitamin D may be the most important thing you can do for your health. You know the usual prescription for good health: a balanced diet with lots of fruits and vegetables, regular exercise, no smoking.Now add this: Spend a little more time in the sun. Huh? That may sound like medical .After all, we've been warned for decades about the dangers of the sun: wrinkles, age spots and the increasing threat of skin cancer.But new and impressive medical evidence suggests that sunlight is beneficial.The vitamin D it our bodies to make may prevent cancer, protect against heart disease and ward off a long list of disorders such as multiple sclerosis, rheumatoid arthritis, diabetes and gum disease.It is even showing promise as a treatment for heart disease and some cancers. Long recognized as vitally important for bone building (it's needed for calcium absorption), vitamin D has now achieved superstar status among nutrients.While all doctors may not agree, many experts are confident enough of its wide-ranging powers to urge that we get much more of it, from the sun and from supplements, as even the best diet in the world may not give us enough.
Answer: To do exercise now and then.
