Teacher: Now, understand the problem? If you are still confused, see the following example:
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: Two travelling angels stopped to spend the night in the home of a wealthy family. The family was impolite and refused to let the angels stay in the guest room. Instead the angels were given a space in the cold underground room. As they made their bed on the hard floor, the older angel saw a hole in the wall and repaired it. When the younger angel asked why, the older angel replied, "Things aren't always what they seem." The next night the pair came to rest at the house of a very poor, but very kind farmer and his wife. After sharing what little food they had, the couple let the angels sleep in their bed where they could have a good night's rest. When the sun came up the next morning, the angels found the farmer and his wife in tears. Their only cow, whose milk had been their only income, lay dead in the field. The younger angel was very angry and asked the older angel, "How could this happen? Why did you not watch out for the cow? The first man had everything, yet you watched over his house," she accused. "The second family had little but was willing to share everything, and you did not help." "Things aren't always what they seem," the older angel replied. "When we stayed in the underground room , I noticed there was gold stored in that hole in the wall. Since the owner was so greedy and unwilling to share his good fortune, I asked God if I could seal the wall so he couldn't find it. Then last night as we slept in the farmer's bed, the angel of death came for his wife. I asked God if the angel could take the cow instead. You see, things aren't always what they seem. "
Answer: Because she didn't like the greedy owner.
Student:
Why did the older angel repair the hole for the rich family?
