单项选择题

In the United States, injuries to passengers involved in automobile accidents are typically more severe than in Europe, where laws require a different kind of safety belt. It is clear from this that the United States needs to adopt more stringent standards for safety belt design to protect automobile passengers better.
Each of the following, if true, weakens the argument above EXCEPT:

A．Europeans are more likely to wear safety belts than are people in the United States.

B．Unlike United States drivers, European drivers receive training in how best to react in the event of an accident to minimize injuries to themselves and to their passengers.

C．Cars built for the European market tend to have more sturdy construction than do cars built for the United States market.

D．Automobile passengers in the United States have a greater statistical chance of being involved in an accident than do passengers in Europe.

E．(E) States that have recently begun requiring the European safety belt have experienced no reduction in the average severity of injuries suffered by passengers in automobile accidents.
