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.（D）

(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.

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

D的意思是乘客在美国比欧洲更有可能出车祸,从而支持结论:United States needs to adopt more stringent standards for safety belt design to protect automobile passengers better.

D 我觉的是无关。因为原文中“are typically more severe than in Europe”，说的是程度，而D描述的是数量。

个人观点：B、C为他因削弱，没有争议；E为有因无果的削弱，也无争议。A为他因消弱，D也有削弱。在A-->B的过程中，攻击了A也属削弱的一咱，D属于攻击A。因此，这5个选项都应为削弱。只是A、D相比起来，D更差一些。个人感觉这题应该是我们自己编的吧，不应是真题！
