Man’s first real invention, and one of the most important inventions in history, was the wheel. All transportation and every machine in the world depend on it.
The wheel is the simplest yet the most remarkable of all inventions, because there are no wheels in nature—no living thing was ever created with wheels. How, then did Man come to invent the wheel Perhaps some early hunters found that they could roll the dead body of a heavy animal through the forest on logs more easily than they could carry it. However, the logs themselves weighed a lot.
It must have taken a great prehistoric thinker a long time to imagine two thin pieces of log collected at their centers by a strong stick. This would roll along just as the logs did, yet it would be much lighter and easier to handle. Thus the wheel and the axle came into being, and with them the first carts were invented.
Which of the following is NOT true

At last a poor old man came to the palace. He was carrying a big jar (坛子) . The old man went into the king’s room and said, "Oh, King, your good father was once a poor man and my father was rich. They were very good friends. My father gave your father a large jar, like this one, and it was full of gold. Your father promised (答应) to give back the gold when he became rich. But he didn’t give it back. Now I’ m poor and you are rich. And I want the gold."
The king said, "I don’t believe that story. The jar is very big. There isn’t enough gold in all my country to fill that jar. My father didn’t tell me anything about a large jar full of gold."
"All right." the old man said, "Never mind. If you don’t believe the story, give me the bag of gold, please." The king remembered the rule and gave the man the bag of gold.
