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: The loneliest chimp in the world just got the best surprise--a hug from a new friend.Ponso has been by himself for nearly three years,finding himself alone after his wife and children died on the island where they were abandoned by a medical testing company many years ago. For years a nearby villager named Germain has been Ponso's only company,visiting him so often to bring bananas and bread--the chimp's only source of food on the tiny island.It was clear how much Ponso missed companionship when he was recently visited by Chimpanzee Conservation Centre Director Estelle Raballand.The chimp immediately embraced Estelle Raballand in a huge hug and laughed as she reached out for him,with his smile from ear to ear. For those who know Ponso's backstory,his immediate ease and trust in humans might be surprising.Ponso was one of 20 chimps,all between the ages of 7 to 11 years old,relocated to an island off the Ivory Coast after being used for testing by the New York Blood Centre.After the tests were completed in 2005,the lab reportedly transferred the chimps to a string of islands,occasionally dropping off food and water because there was none in the chimps' new homes. Disease and hunger soon left only Ponso,his mate and their two children standing.But at the end of 2013 they died within days of each other and Ponso was now completely alone. A group called SOS PONSO is trying to raise money for the poor lonely chimp,already achieving its goal of $20,000--all of which will be used for Ponso's care. 
 Answer: He suffers from loneliness greatly.
Solution:
What do we know about the chimp Ponso?
