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: Are you a big fan of pirate stories? Do you know how to talk like a pirate? You can have fun on September 19th. This special holiday is called International Talk Like A Pirate Day. It was invented in 1995 by two young Americans, John Baur and Mark Summers. These two good friends came up with this idea when they were playing racquetball, and began to talk like pirates. At that moment, they thought, "Young people are interested in pirate, but there is no such a chance for people to get together to share it. Why not have a day when everybody talks like a pirate?" They decided to make September 19th the date. Since then, Baur and Summers have tried hard to promote Talk Like A Pirate Day. As Baur said, "We've talked like pirates, and encouraged several of our friends to do so every September 19th." At first, this day was only known by a few people. In 2002, Baur and Summers sent a letter about their invented holiday to Dave Barry. This columnist really liked their idea. He promoted the holiday and made it known to more and more people. Now, it has really become an international holiday. On Talk Like A Pirate Day, you need to dress like a pirate. You should wear a big hat or maybe cover one of your eyes. You can pretend to be any kind of pirate that you can find in any story or movie. Having fun and being relaxed are not the only best things about the holiday. Young people share the same interest and childhood dreams that day. That's why it is welcomed by so many people, especially young people. Unlike traditional holidays, International Talk Like A Pirate Day is a brand new holiday which is invented by the youth themselves and celebrated by themselves too. Because of Baur and Summers' imagination and creativity, thousands of young people's pirate dream come true. Next time, when you have a good idea, why not share it with your fiends and insist on your belief? Maybe you can create another wonderful holiday for the youth in the future.
