单项选择题

An old man visited a new doctor. He was very young. "I don’t feel well, doctor," he said, "Please find out what’s wrong with me."
"Take off your clothes and lie on the bed," the young doctor said, "I’ll examine you." The old man took off his clothes and lay down on the bed, and the young doctor examined him.
However, he couldn’t find anything wrong with the old man. He listened to his heart. He looked into his throat. He examined every part of him. At last he said, "I’m sorry, but I can’t find anything wrong with you. You’re as healthy as I am." "That’s very strange," the old man said, "because I feel really bad."
"Come back tomorrow and see me again if you don’t feel better." The young doctor said, "I’ll examine you again." "All right, doctor," the old man said. Slowly, he stood up and put on his clothes. Then he walked out of the hospital.

What did the doctor think
A. He thought the old man was healthy.
B. He thought the old man was very ill.
C. He thought the man had heart problems.

A few seconds later, the doctor’s nurse ran in. "Doctor! Doctor!" she cried. "That man you said was healthy has just died outside the door." The doctor thought quickly, "Then turn the body around so that people will think he was coming in," he said.
