On a Cold Winter Day, a Slipped on the Icy

True/False

On a cold winter day, A slipped on the icy sidewalk at the entrance to B's shop. A injured her ankle as a result of the fall, and B hired a taxi to have her taken to the hospital to have her injured ankle examined. On the way to the hospital another automobile collided with the taxi, and A was seriously injured. The injured ankle was the proximate cause of A's more serious injury in the automobile accident, because B had hired the taxi to send her to the hospital.
