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.

Let me give you an 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.
The answer to this example can be: How many books are there in the British Library?
Here is why: In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.

OK. solve this:
Article: Last night I had a terrible nightmare. I imagined that I was falling between the walls of a deep valley. I was screaming as the ground rushed towards me. I was sure that I was going to die. Suddenly, I was awake, sweaty but amazingly alive. I was angry with myself. According to popular stories I am to blame for the bad dream. I had eaten a big piece of cheese before bedtime. Cheese, says folk stories, causes nightmares. One minute I'm eating a piece of cheddar (a kind of cheese), the next _ 'm falling through a canyon . It's not just folk stories that suggests Roquefort and Red Leicester (two types of cheese) give you nightmares. Scientists seem to agree. Cheese contains a substance that makes our bodies produce a chemical called serotonin. Serotonin slows down the heart and so our blood slows down around our bodies. When we're awake, this can lead to headaches. When we're asleep this gives us strong dreams. Cheese is also hard to digest and may make us sleep badly. We are more likely to wake during deep sleep and remember any dreams or nightmares. Don't think that removing cheese from your late night meals will stop the nightmares. Bananas, chocolate and tomatoes all have the same effect.
Answer: Bad dreams may have a cheese explanation.
