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: In 1997, a group of twenty British women made history. Working in five teams with four women in each team, they walked to the North Pole. Apart from one experienced female guide, the other women were all ordinary people who had never done anything like this in their lives before. They managed to survive in an environment which had defeated several very experienced men during the same time period. The women set off as soon as they were ready. Once on the ice, each woman had to ski along while dragging a sledge weighing over 50 kilos. The temperature was always below the freezing point and sometimes strong winds made walking while pulling so much weight almost impossible. It was also very difficult for them to put up their tents when they stopped each night. In such conditions, the women were making good progress if they covered fourteen or fifteen kilometers a day. But there was another problem. Part of the journey was across a frozen sea with moving water underneath the ice and at some points the team would drift back more than five kilometers during the night. That meant that after walking in these very severe conditions for ten hours on one day, they had to spend part of the next day covering the same ground again. Furthermore, each day it took three hours from waking up to setting off and another three hours every evening to set up the camp and prepare the evening meal. So, how did they manage to succeed? They realized that they were part of a team. If any one of them didn't pull her sledge or get her job done, she would endanger the success of the whole expedition. Any form of selfishness could result in the efforts of everyone else being completely wasted, so personal Feelings had to be put on one side. At the end of their journey, the women agreed that it was mental effort far more than physical fitness that got them to the North Pole.
Answer: The women had not met one another before.
Solution:
What was so extraordinary about the expedition?
