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: Charlie Chaplin was one of the greatest and most widely loved silent movie stars. From Easy Street (1917) to Modern Times (1936), he made many of the funniest and most popular films of his time. He is best known for his character "the little tramp ". It is this kind-hearted character that we connect with the time of silent movies. Born in London in 1889, Chaplin first visited America with a theater company in 1907. Appearing as Billy in the play Sherlock Holmes, the young Chaplin toured the country twice. On his second tour, he met Mack Sennett and was signed to Keystone Studios to act in films. In 1914, Chaplin made his first short film, Making a Living. That same year, he made thirty-four more short films. These early silent shorts allowed very little time for anything but physical comedy, and Chaplin was extremely good at it. Chaplin was known as one of the most demanding men in Hollywood. No matter how big or tiny the size of the part, Chaplin walked each actor through every scene. Chaplin knew that a successful scene wasn't simply about the star, but about everyone on the screen. He required that all the actors and actresses work together in every performance. The only way to achieve it was to keep complete control over every scene. As he became more popular, he used more and more creative and difficult filming techniques. Movies such as his 1925 hit, The Gold Rush, required endless reworking of scenes and rebuilding of sets. Though Chaplin is of the silent movie era, his achievements were carried over into the films of today. His strictness and concern for the processes of acting and directing made his films great and led the way to a new and more wonderful cinema. Chaplin's working life in entertainment lasted over 75 years, from the Victorian stage and the music hall in the United Kingdom as a child performer, until close to his death at the age of 88.
