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 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.

跟C无关吧，跟他工作在几个不同医院无关，而是只要证明，确实用这个XRAY照过的病人没有发现FRACTURE OF ANKLE。就能证明这个XRAY没有啥用，然后说明这其实就是浪费钱吧。

个人认为是b。

因为c范围不对。
