A、A passenger; B、The dog. C、The truck-driver. D、A policeman. CWho was hurt in the disaster?

A small dog brought disaster to a small English town last week. It was trying to cross a busy street but was too frightened to leave the strip in the middle of the street.
    A truck driver parked his truck on the side of the road and got out to help it. While he was going to get the dog, his track rolled down the street. It smashed into four parked cars, crashed through a fence, rolled down a bank and smashed into a row of houses. Only the driver was hurt. The dog bit him on the hand while he was carrying it.
    Here is another story about dogs. A nine-year-old child, who nearly drowned while she was swimming in a home swimming pool, was saved by the family dog on Saturday. The child was alone in the large pool at the time.
    The family of the dog said it would receive an extra large bone as a reward.
