请教 GWD-24-22 这种削弱方式从没见过。。。

24-22 Often patients with ankle fractures that are stable, and thus do not require surgery, are given follow-up x-ray because their orthopedists are concerned about possibly having misjudged the stability of the fracture. When a number of follow-up x-rays were reviewed, however, all the fractures that had initially been judged stable were found to have healed correctly. Therefore, it is a waste of money to order follow-up x-rays of ankle fracture initially judged stable.

Which of the following, if true, most strengthens the argument?  

A)   Doctors who are general practitioners rather than orthopedists are less likely than orthopedists to judge the stability of an ankle fracture correctly.

B)    Many ankle injuries for which an initial x-ray is ordered are revealed by the x-ray not to involve any fracture of the ankle.

C)    X-rays of patients of many different orthopedists working in several hospitals were reviewed.

D)   The healing of ankle fractures that have been surgically repaired is always checked by means of a follow-up x-ray.

E)     Orthopedists routinely order follow-up x-rays for fractures of bone other than ankle bones.

ans: B

我选C。 原文是说ankle 骨折的病人骨折病情是稳定的，所以不需要手术。而B是说的是另一回事，B是说没有骨折的ankle受伤者，应是无关选项。

而C是加强了原文的前提，即：follow-up的X-rays 被reviewed的范围更大。结合原文：all the fractures that had initially been judged stable were found to have healed correctly， 应是一很好的加强！

请NNS指点！

答案应该是C。

C的意思为：被检查的那些X-RAYS（原文用去证明那些骨伤愈合的好的X-RAYS）来之于不同医院的很多矫正师。说明证据有代表性，支持结论

没见过这道题，是新题吗？请问哪里有下？

我的想法是选B. 原文说为了防止误诊，需要照x光来确定。但是大量的x光片证据显示原先的诊断是正确的。结论是使用x随诊浪费钱是不必要的。（没有精确翻译，只是说明大意）B：很多需要随诊的病例（注意是已经有该病症存在的情况才需要随诊），X光显示没有该病症的存在。 因此进一步说明x光不仅浪费，而且根本没有起到帮助确诊病情的作用。所以加强结论。 不知考虑得对不对。 望nn来帮助“确诊”。

我太罗嗦了，但我要说的是看来自己以后发贴要更慎重些，不要误导别人并且增加斑竹工作量。再次检讨。

谢谢战友们的解答！

good luck to everyone who are persistant and wordinghard!
