Q 22: 调查类

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.

通常由于整形医师被认为对骨折的Stability有误诊现象,所以有踝骨折的病人会给与gollow-up-rays

检查A number of Follow-up-rays,发现已开始被诊断为Stable的骨折都愈合得很好。所以给与一开始就被诊断为Stable的病人Follow-up-rays是在浪费钱。

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.









答案选的B,理由是这样一来X-rays就是有代表性的?。。。。我怎么记得XDF说过有一种错误选项叫诉诸于大众权威?。。。。这个选项的加强理由好奇怪啊,有没有好一点的解释?谢谢大家!~~~
