一道所谓真题，请教！

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 stablility 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 judge 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 ankel 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 nakle 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.

我选C。我觉得C可以看成是排除他因，说明review是有代表性的。

我觉得毛虫分析的很有道理.

不过为什么么不能是E呢? 说这些整形医师不管对什么骨折都routinely order照X光.---说明这些整形医师提的建议并没有针对性,因此是waste.

现在我自己都有点糊涂了......

一道所谓真题?

这个题目是LSAT上的逻辑题啊？

我选B。题目说因为x-ray 的结果总是和整形师最初的诊断一致，所以拍片没必要，是浪费钱的。

要支持这个结论，就是要说明x-ray 的确无法判断实际受伤的情况。而B提到大部分的脚踝受伤情况经x-ray 验证没有任何的骨折。说明使用x-ray 没用。即支持了原文的结论。

May I ask what is the key to this question?

I have searched the answer in Daquan, but failed.

AND could anybody explain what's the meaning of branch C?

Jetrong gg, 你能提供一下答案吗?

好让我们这些人的心不要老悬在这呀...

B.

A，错误的比较。C、D、E都是无关选项。
