### HideShow timer Statistics

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?

(A) During the winter, the U.S. has an unusually large number of icy roadways.
(B) Cars can be just as likely to skid and spin out just after the beginning of a snowstorm as when roads are covered by patches of ice.
(C) Prior to the introduction of anti-lock brakes in American cars, more drivers skidded and spun out in the U.S. than in any other country.
(D) After 1980, many U.S. drivers who had specifically avoided driving in icy conditions no longer did so.
(E) Many drivers skid and spin out on ice because they fail to steer appropriately rather than because their cars lack anti-lock brakes.

Simple Q

A, B & C are out of context & doesn't explain why change came post 1980
E doesn't explains why the increase has happened post 1980
D clearly explains why the change happened post 1980

+1 D

The key in this type of questions is to notice what changed after the date we are analyzing. In this case, 1980.
The majority of the rest of choices talk about general facts that could take place before or after 1980. So, they can't solve the paradox.

(A) During the winter, the U.S. has an unusually large number of icy roadways. => the # of accident did not relate to the number of icy roadways
(B) Cars can be just as likely to skid and spin out just after the beginning of a snowstorm as when roads are covered by patches of ice. => the condition of icy road is also out of scope
(C) Prior to the introduction of anti-lock brakes in American cars, more drivers skidded and spun out in the U.S. than in any other country. => talking about other countries is also out of scope
(D) After 1980, many U.S. drivers who had specifically avoided driving in icy conditions no longer did so. => the behavior that have effect to the number of cars use icy roadway will impact negatively to the number of accidents
(E) Many drivers skid and spin out on ice because they fail to steer appropriately rather than because their cars lack anti-lock brakes. => does not related to anti-lock brakes

I was confused between D and E.
I thought in E the increase in the number of drivers who skidded and spun out on ice is because they fail to steer appropriately, although the cars use anti-lock brakes. how could D better than E?
