Mr. David’s telephone number was 476032, and the number of the cinema was 476023, so people often made a mistake and telephoned her when they wanted the cinema. One evening the telephone bell rang and Mrs. David answered it. A tired man said, "At what time does the last film begin "Tm sorry," said Mrs. David; "but you have the wrong number. This is not the cinema." "Oh, sorry, it began twenty minutes ago Goodbye," said the man. Mrs. David was very surprised, so she told her husband. He laughed and said, "The man’s wife wanted to go to the cinema, but he was feeling tired, so he telephoned the cinema. His wife hears him, but she couldn’t hear you. Now they will stay at home this evening, and the husband will be happy. Why did Mr. David think that the man and his wife would stay at home
A. Because they were late for the last film.
B. Because the cinema was closed.
C. Because they were not sure about the time of the last film.
