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: Pupils work harder in lessons if they are taught by a man, a study has claimed. Male teachers are more likely to improve pupils' self-esteem and are judged by pupils to be more fair, according to a study published by the Department for Education. But there is a significant shortage of male teachers, especially in primary schools, with reports last month indicating that almost one in three primaries has an all-female teaching staff. The latest figures heightened fears that schools are becoming dominated by women and children are being denied access to male role models in the classroom. Researchers at the London School of Economics and Westminster University conducted an experiment in which each of 1,200 pupils in 29 schools was given PS2. They could use the money to "buy" up to 10 questions at a cost of 20p each, which they then had to answer. If they were right they were given an extra 20p, but if they were wrong they lost 20p. Boys and girls who had a male teacher chose on average almost half a question more than those taught by women, indicating that they had a more positive outlook on the rewards of effort, the the study said. Researchers wrote: "One of the most significant results featured in this experiment is the positive effect of male teachers on effort. The experiment suggests that higher ability pupils either believed that the teacher would reward them more favorably or had a preference for working hard to please the teacher." According to the Good Teacher Training Guide, 86 per cent of new teachers entering primary schools are female, along with 62 per cent of those entering secondary schools. Professor Alan Smithers, of Buckingham University, said: "This is an interesting and somewhat surprising finding, but it does underline the importance of having a good mix of male and female teachers in classes."
Answer: The author thinks that male teachers are better than female teachers.
