An old scientist recently made several tests with different animals to find out which was cleverer than
other animals.
In one test the old scientist put a monkey in a room where there were several boxes. Some boxes were
inside other boxes. One small box had some food in it. The scientist wanted to watch the monkey and to
find out how long it would take the monkey to find the food. The scientist left the room. He waited a few
minutes outside the door. Then he got down on his knees (膝盖) and put his eyes to the keyhole. What did
he see? To his surprise, he found himself looking into the eye of the monkey. The monkey was on the other
side of the door and looked at the scientist through the keyhole.
