一道GMAT逻辑真题!
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 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
我觉得一楼这个理解有点不对，原文说的不是这个x-ray要不要被review,而是follow-up x-ray是做还是不做的问题。你的解释我觉得是对的！但是B并不是削弱，我觉得应该算not mentioned

先看问题.问的是support,即逻辑题为演绎类.因此答案找范围与原文相关选项即可.
读原文,大概意思是O这帮人通过follow-up x-ray来确定病人ankle fracture是否stable.但是follow-up x-ray这个东西被review之后跟没有review没什么区别.因此,follow-up x-ray这东西再做就是浪费钱.
看选项.
A说D这么一个东西比O这么一个东西再judge fracture上有一个不同,原文没提,排除了.
B说ankle injuries被x-ray reveal出来没有involve ankle的fracture.（既然没有fracture,当然需要follow-up（后续）的x-ray了.那么follow-up x-ray是必须的而不是浪费钱的.--所以此选项为驳斥,而不是支持.）
C说病人的x-ray这东西被不同的O已经review过了.（因此,x-ray这个东西在开始的时候做一次就够了,follow-up就是浪费银子.）
D说手术治愈ankle fractures这个东西需要check by follow-up x-ray.完全没提,排除.
E说O这帮人通常需要follow-up x-ray来怎么fractures of bone比ankle bone.这个对比关系原文完全没提,所以排除了.
读的这么残疾还是能排除ADE,而只有B和C选项是和原文范围相关的.而二者一个支持,一个驳斥,选出支持原文的C选项即可.
其实不就是一回事么,如果当x-ray被O这帮人review了之后,那么follow-up的x-ray自然没有必要做了.原文也提到了,由于多次review会发现一开始这个情况就能确定,因此再做follow-up的x-ray是浪费钱.即x-ray被O这帮人review是一个前提条件.
B选项亦是如此,说这个x-ray不包括facture,而原文的前提就是这个fracture是应该被x-ray照出来并可以judge的.无论是无关,或是驳斥,也不影响你做题.
分析错题需要分析当时做错的思路到底是如何想错了的,而不是从答案倒推去挑错.
