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:
Europeans are more likely to wear safety belts than are people in the United States.
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.
Cars built for the European market tend to have more sturdy construction than do cars built for the United States market.
Automobile passengers in the United States have a greater statistical chance of being involved in an accident than do passengers in Europe.
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.
① weaken+except
② US car accident +serious> EU, ∵ EU has diff safety belt ∴EU→US + severe car accident
A:欧洲人系安全带的可能性要高于美国人，提出他因，可以削弱，排除；
B：欧洲人接受了相关训练，美国人没有，提出他因，可以削弱，排除
C：欧洲的车比美国的车更坚固，提出他因，可以削弱，排除；
D：统计上美国人比欧洲人更容易发生车祸：更容易发生车祸≠更容易发生严重的车祸，看起来并不能削弱题目，保留
E：采用了欧洲安全带的州发现车祸的平均严重程度并没有下降→削弱因为安全带造成区别这个原因
综上，D
将weakens the argument above EXCEPT转换成加强或不能削弱。
weak except
可以先找出有weaken的 排除
或是想成加強(以USA他因觀點出發)
因為WEAKEN得從英國他因或是USA削弱出發
D-就算事故率高但不妨碍用了好的安全带降低损伤（研究的是损伤严重程度问题而非频率）
加强或不能削弱
be likely to do sth 强调可能性，而不是做了某事
D 受伤严重程度和发生事故率不一样
E 用欧洲的安全带 严重程度没减少 说明美国安全带设计标准与受伤严重程度的关系削弱
注意是欧洲 require a different kind of safety belt，而不是require a safety belt，所以问的是哪个不能削弱确实是因为欧洲的安全带质量更好。
事故发生率高并不能等同于受伤更严重，不能削弱安全带的改良有效果
C. 欧洲市场的汽车质量更好，因此有理由相信injuries are less severe 不是因为它独特的安全带，而是因为车的质量。因此削弱了结论。
D. Correct. This choice does not weaken the argument. The higher likelihood that one is involved in an automobile accident in the U.S. actually has no bearing on the higher rate of severe injury among passengers who are involved in automobile accidents. That is, the rate itself is a proportion of the total number of passengers involved in accidents rather than the number itself. This rate would remain the same whether 10 accidents or 10 million accidents occurred.
