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
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
