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.

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: Although Thomas Edison created the technologies behind three major 21st century industries electrical power,recorded music and movies--his greatest invention may have been the modern method of inventing.He basically came up with the modern system of research and development.Edison was not the only scientist doing research in his garage but someone who gathered around him a team of creative scientific minds.Edison's 1aboratories were the forerunners of Apple,Google and Microsoft. Yet for a11 his scientific gifts,he was no Steve Jobs or Bill Gates.He once said,"Anything that won' t sell,I don' t want to invent." But Edison,unlike Jobs or Gates,had no real sense of what the public wanted or how to change his discoveries into products that might sell.It took him years to understand that the phonograph was not a business tool but an entertainment invention.He helped create movies but resisted the idea that people might want to go into a theater to watch one. We chose Edison this year because we need his example now more than ever.Though we live in a time of great reformation,the U.S.is in danger of losing its advantage in science and technology.American investment in research and development has not increased as a percentage of GDP since the mid1980s,while the government' s share has been dropping.And this is at a time when China is rapidly increasing its money on research and development.The U.S.was once among the 1eading nations.Now it ranks near the bottom of the 23 nations that collect such data.We hope that Edison' s story might not only encourage reformation but also inspire more young Americans to study science and engineering.
Answer: Edison wanted to invent things that sold well.
