Write a multi-choice question for the following article, with the given choices and answer: Article: People have different ways of greeting each other. They might shake hands , kiss or hug . But do you ever wonder how dogs say hello? If you are a dog lover, you already know the answer to this question. When you arrive home, your dog jumps up into your lap . It wags its tail, and sometimes gives you wet kisses. Like humans, dogs have five senses : smell, touch, sight, hearing and taste. Humans use sight as the main sense for recognizing one another. But dogs have poor eyesight. They use smell to recognize others. A dog's sense of smell is much better than a human's. It is through its sense of smell that tells the differences between different people. Dogs use smell to recognize other dogs, too. They tell the differences by the smell of pee and pooh . When two dogs meet, they smell each other's noses. Then they go side to side, and smell each other's butts . By smelling its friend's behind, a dog knows who it is with. That is also why dogs smell everything they can on the road. By smelling grass, trees and signposts , dogs know which other neighborhood dogs have been around. Options: A They use eyes to recognize each other. B They use sound to recognize each other. C They use smell to recognize each other. D They use touch to recognize each other. Answer: C They use smell to recognize each other. Question:

Write a multi-choice question for the following article, with the given choices and answer: Article: Long ago ,there lived in Greece a learned man. He was so well known for his good knowledge of almost everything that lots of people from all over the country came to learn from him. The great man taught his students whole-heartedly and answered their questions with great patience. One day a student asked him, " My dear teacher, didn't you say you yourself have many ,many more questions about things than we do? But I think we students have far more than you." With a smile on his face, the teacher drew two circles ,one as large as a big cake, the other smaller. Then he said , "Of course, I have learned much more. But it's wrong to think that a teacher has fewer questions than his students. Now, look at these two circles. The inside of the bigger one is my knowledge of things, and the inside of the smaller one is yours. Out of the circles is what is still unknown to us. Since mine is larger, I have to use the longer line to draw the bigger circle. That means I have more opportunities to face what is still unknown. And that's why I myself have more questions than you do. The more you learn , the more questions you have. You will never learn enough ,you know." Options: A he was good at drawing circles B his knowledge had something to do with the circles C why he had more questions than the students D how he could get more knowledge Answer: C why he had more questions than the students Question:
