Problem: 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?
Explanation: In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.

Problem: Article: For those who have lonely nights and have trouble falling asleep, he is proving the ideal partner. This is a man who does not snore in bed. And he is happy to wrap a comforting arm around his dearest until morning arrives. He does exist. He is the body-shaped pillow, the latest sleeping aid from Japan. This pillow comes without a head and is filled with foam. It's made by _ and has a "body" and a flexible arm that can be curled around its owner. About 1,000 of the pillows have been sold since they went on sale in Japan last year and many buyers say they are pleased with their sleeping companion. "This pillow makes me feel relaxed because I can hold the arm and feel something warm at my side," said 34-year-old radio DJ Junko Suzuki. But according to _ , the pillow is more than just an emotional help for those tired of spending the night alone. And it is shaped, the firm says, to support its partner on both sides to ensure a night of good sleep. The idea is to curl up in between the body and the flexible arm. The head just rests on the pillow's "arm muscles". "My grandmother used to say that there is no more comfortable pillow than another person," said the firm president, Tomoki Kakehashi. "So I thought that maybe people would want to sleep on a pillow shaped like an arm." The pillows, on sale only in Japan for the moment, cost 8,500 yen(around US$80) each and come with shirt-or shirt-shaped pillow covers in blue, pink or green.
Answer: The idea of body-shaped pillow is from what an old lady said.
