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?
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: Richard Rodriguez from the United States is a great roller coaster fan. Recently he broke his 15th world record after he spent 104 days riding the world's largest roller coaster. "It got more difficult to ride and ride because of the muscle tiredness," Rodriguez, a teacher at the University of Chicago, said as he stepped down from the ride in a German park. He spent 10 hours a day on the roller coaster. Rodriguez tried to keep himself busy during the rides on the big roller coaster in a southwestern town in Germany. "I read the newspapers...I have a walkman, I have my cellphone, so I try to talk to people and message people during the day," he said. Although the 42yearold said he felt sick on the first few days, he said he soon got over the problem. "My face hurts sharply and I have a little backache, but I am good." The "Expedition GeForce" is one of the world's biggest roller coasters. It measures 62 meters at its highest point. On his 95th day on the coaster, after travelling over 25,000 kilometers, Rodriguez had a toothache and was treated by a local dentist. He went on after that and succeeded in breaking the record. Rodriguez celebrated with members of the park staff and his supporters, who had sent him postcards and emails encouraging him not to give up.
