Answer the following question: Read the article and select the best answer. Article: Two old men lived in a room on the third floor of an old people's home. Both men were very old and badly ill, and they spent 24 hours a day in bed in the room. Luckily, one of the old men had his bed by the window, and every day he spent hours telling his friend far from the window what he could see through the window. He told him about the traffic going by, the children playing in the park opposite, and the birds flying in trees. The old man far from the window got a lot of pleasure from hearing about the world outside, but after a time he began to get rather unhappy. How nice it would be, he thought, if he had the bed by the window and could see everything for him, instead of just hearing about it. One night, the man by the window called to his friend, "Quick! Pull the alarm by your bed; I don't think I can get through the night!" But his friends, expecting an empty bed by the window, did nothing---he just closed his eyes and went back to sleep. The next morning, the nurse found the man dead in his bed by the window. The old man was very excited as they moved him into the empty bed by the window. He sat up in bed, pulled back the curtain, looked out --- and saw only a wall. Question: In fact, there was _ outside the window. Options: A: a garden B: a park C: a wall D: a picture
Answer:
C
