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.

Solution: How many books are there in the British Library?
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.

New input: Article: Monty Roberts was the son of a poor family. He liked horses. He had a dream to own a horse ranch   ever since he was a little child. One day when he was at high school, he was asked to write a paper. It was about what he wanted to be and do when he grew up. He worked hard on it, and wrote a seven-page paper. In the paper he described his dream of owning a big horse ranch someday. The next day he handed it in to his teacher. Two days later he received his paper back. On the front page was a large red F(fail) with a note that read, "See me after class." He went to see the teacher after class and asked, "Why did I receive an F?" The teacher answered, "This is an unrealistic dream for a young boy like you. You come from a poor family. You have no money. Owning a horse ranch needs a lot of money. You have to buy the land.  _ " Then he added, "Write this paper again. If you write it with a realistic plan, you may receive a better grade." After sitting with it for a week, he turned in the same paper, making no changes at all. He said to the teacher, "You can keep the F and I'll keep my dream." Monty kept his dream and worked very hard. Today he owns a large horse ranch with a big house on it, and he keeps that school paper he wrote on the wall of his sitting room. Last summer the same school teacher came to visit him. When the teacher was leaving, he said, "Look, Monty, when I was your teacher, I was something of a dream stealer. During those years I stole a lot of children's dreams. It was lucky that you hadn't given up yours." Don't let anyone steal your dream. Follow your dream, no matter what. 
 Answer: To receive a better grade.
