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.

拙见，供参考。
我选A。如果不是这个答案下面就不看了。
原文的意思：
1。如果整形外科医生判断一个脚踝骨折病人stable，不需要手术，病人通常被要求做X光检查，因为整形外科医生需要确认自己的判断，排除误判的可能。
2。重新检查x光检查结果发现，整形外科医生一开始就判断为stable的，全都正常康复了。
3。结论，如果整形外科医生一开始就人为stable，x光检查就不必要了，也就是浪费。
原文逻辑：
整形外科医生判断stable-------->病人确实stable，不需要x光检查
其理由是x光检查结果和整形外科医生的stable判断是一致的
题目要求加强：
A。整形外科医生对stable的判断比其他医生准确。
B。很多踝伤的x光检查结果表明没有骨折发生。这与原文的前提ankle fracture 不一致。迷惑选项。
C。很多医院都会重新检查整形外科医生的病人的x光检查结果。有点削弱的意思，重查摆明是不信任嘛。
D。所有手术治愈的脚踝骨折病人（not stable的）都经过了x光检查。无关。
E。除了脚踝骨折的病人，整形外科医生要求其他部分骨折的病人做例行x光检查。看似有点象，既然所有脚踝有病的都不做x光检查，那上面那个问题哪里来的？
