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.
One 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 is here: How many books are there in the British Library?
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.

Now, solve this: Article: Not all vegetables need lots of sunshine. Mark Hoffman and his wife own a bed-and-breakfast guesthouse in rural Kempton, Illinois. They often serve their guests fresh products from the garden. The Hoffmans have been growing food and flowers for twenty-five years. For almost ten of those years, Mr. Hoffman has been experimenting and working with shade plantings. He says, "The bottom line here is that most plants will produce more in full sun. But if you do not have full sun, there are other choices." For example, he grows tomatoes near oak trees. Oak trees can produce a lot of shade. But Mr. Hoffman says his tomato plants grow as long as they get five hours' direct sunshine a day, especially morning sun. Not only does this go against the traditional advice that tomatoes need six, eight, even twelve hours' full sun a day. It also shows how plants and tree roots can share nutrients and water. Mr. Hoffman says plants with wider leaves seem to do better in shady environments. He also found that his potatoes did better partly in shade than in full sun. Moving them out of the sun helped control an insect problem. Mr. Hoffman does not use pesticide . Instead, he planted the potatoes in the shade, especially on the east side of the tree. The potatoes get morning sun, but they are shaded during the hottest part of the day. Some insects dislike shade, and the hottest part day is when they do the worst of their damage. Time of day, sun intensity , shadows from trees, walls and buildings all influence how much sunlight falls on plants. And people interested in shade planting should also remember something else. The term "shade" can describe different amounts of darkness. It can even mean different things in different parts of the world.
Answer: five hours a day
Solution:
How many hours of sunshine are enough to keep tomato plants growing in Hoffman's garden?
