GWD-24-Q 22:
Often patients with ankle fractures that are stable, and thus do not
require surgery, are given follow-up x-rays 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.
参考答案C。但是觉得C很模糊，不知道说的什么，请高手指点。谢谢
原文大意：
因为——怕误诊而拍照x片，
并没有显示误诊情况出现
所以——没必要拍照
本题加强原因即可，也就是加强“没有误诊”这个前提。
C的意思是：病人的x片已经被多家医院的多个医生看过了。（因此，不太可能出现意见不统一而造成的误诊）
