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: One Canada, Two Languages Canada is one of the few nations in the world to have two official languages: English and French. There are 10 provinces in the country but only one of these--Quebec is known as "French Canada". This is because it was founded by French explorers while British adventurers discovered the rest. Canada left the British empire in 1867 to become an independent country, and English and French have been recognized as the official languages ever since. Most people speak English as their first language and the two national television networks broadcast in English throughout the country. Apart from in Quebec and a few places on the east coast, French television is very rare. The same goes for traffic signs and menus. For example, outside of Quebec, there are only a few places where you'll see traffic signs in French. In restaurants, it's almost impossible to find French on the menu unless you are in the heartland of French Canada. However, all products sold in Canada must, by law, have labels and instructions in both languages. In Canada's English speaking provinces, official bilingualism means that students can choose to complete a special French language course. Under this programme, they are taught most of their subjects in French. If a student begins the course in kindergarten or Grade One, it is likely that all their lessons will be in French. However, if they start at junior high school,25 per cent of the teaching will continue to be in English.
Answer: Ten.
