大全-10-20.   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.
请问E不是加强吗？即使用了欧洲的好的安全带重伤程度也没降低那就说明没用咯，为什么不选E呢？B中的statistical chance是什么意思呢？

谢谢解答！！！

本题选Ｄ没有问题．

Ｄ中的statistical chance是指＂统计的机会＂．

Ｅ不是加强是削弱，是从措施不可行的角度说的，问中说　Ｂ（有Ｅ的安全带，Ｅ的事故不严重）－－－＞Ａ（应该在美也用Ｅ的安全带）．Ｅ削弱说这个措施不可行，因为实践得出结论，不好用，因为严重程度没有下降．
