A professor(教授）from New York University once went a remote area to do some science research（研究）. One day, he ate something wrong and became sick, but it was too far to go to the city. "I have to see a doctor," he said to a local（当地人）.

"How can I be sure of getting a good one?"

"It's easy," was the reply. "Every time a doctor loses a patient(病人）, it's our law that he must fly a balloon above his office."

So he began his search. One doctor flew 20 balloons, another 30. Then the professor found an office that was flying only five and went in.
