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: I believe I've gotten this more than once. One lady told me she thought I was 12 and even told her 14-year-old daughter the same. I saw lots of surprised faces because people were told I was actually 19 years old. I'm actually 19 years old, which isn't much of a problem. I'm like the oldest of my friends and the shortest, which is pretty funny. That's probably one of the reasons I fit in so well with them. I volunteered at a weekend school teaching young children. Parents always looked me up and down like "why is this 13-year-old girl teaching my child?!??!?" I guessed it was because I'm also petite ,and I didn't know whether I had a childish face...??? Sometimes I found it funny, sometimes I found it annoying . But I just shrugged it off at last. You know, soon enough people got to know me and then realized I was not actually a 13-year-old girl. This short thing used to be a problem for me, though. I was very very small when I was younger, so kids would _ me. When I was 12, 8-year-old girls would look down at me like "I CAN'TBELIEVEYOU'RETWELVE!" I had always wanted to be tall. But now that I'm older, I got used to it, and I actually love it. You know, I'm fun sized!
