Prior to 1980, many American-made cars did not have anti-lock brakes. These brakes help to prevent cars from skidding and spinning out on ice, and would therefore seem to increase driver control. However, after 1980, when all American-made cars were manufactured with anti-lock brakes, the number of U.S. drivers who experience car accidents due to skidding or spinning out on ice increased by 4 percent annually.

Which of the following, if true, most helps to explain the increase in the number of drivers who skidded and spun out on ice?

【选项】Many drivers skid and spin out on ice because they fail to steer appropriately rather than because their cars lack anti-lock brakes
