[单项选择]

There was a river with a small town on either side of it. The towns were linked by a bridge.
One day, a hole appeared in the bridge. Both towns agreed that the hole should be mended. However, disagreement came up as to who should mend it. Each town thought that it had a better reason for the other to mend the hole. The town on the right bank said that it was at the end of the road, so the left-bank town should mend the hole. The town on the left bank, on the other hand, insisted that all the traffic came to the right-bank town, so it was in their interest to mend the bridge.
The quarrel went on and on, and so did the hole. The more it went on, the more the hostility between the two towns grew.
One day a man fell into the hole and broke his leg. People from both towns questioned him closely about whether he was walking from the right bank to the left or from the left bank to the right, in order to decide which town should be blamed for the accident. But he
A. had one of his legs broken
B. was busy changing the axle
C. had drunk too much wine
D. was afraid to blame anybody
