GWD-24-22

搜索了一下，没有找到这题，置顶的GWD汇总里好像也完全没有第24套中的题，所以发一个新贴。

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 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.

参考答案给的是B。我作题的时候感觉五个选项都不太象，请大家指点！

c，讨论过，其含义是说，这个现象是普遍的，因此可以得到generalized的结论。我考试就遇到了这个题目。

好像是“一道真题”
