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 frac-
ture. 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 frac-
ture 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.
Answer b

我选的C，我想问一下B为什么对，Many ankle injuries 是不是比原文说的fracture的范围要宽啊，是不是超出题目范围了呢？谢谢，请高手指教

我跟楼主选的是一样的…

我认为B选中的an initial x-ray与文章表示follow-up x-rays两个是不同的涵义,
            

假设有ankle fractures进去医院, 必定先做initial x-ray后, 再由医师判断是否要做follow-up x-rays,

B选不能支持文章表述这个follow-up x-rays是浪费钱的

相对地, C选表示这个review是由不同家orthopedists的做出的结果, 所以相对biases会较低,

从而支持结论表示: it is a waste of money to order follow-up x-rays of ankle fracture initially judged stable.

 

请指教

lily同学又是你啊，相对地, C选表示这个review是由不同家orthopedists的做出的结果, 所以相对biases会较低，这个有何而来，对wasteful与否有影响吗，这点我不敢苟同，版主同志能不能出来给讲解一下？谢过

是选C啊

谁说选B了？

结论说的是follow-up X-ray B说的是initial，认为B无关

Drakedragon

initial。。。与follow-up一个是诊前一个是诊后吧，哦，忽视了，这样看可能确实无关，版主同志我再问一句，那C我选的时候理解就是题目中说这个review确实无用，而C说，这种review又是很普遍的，是这个意思吗，请指教，谢过
