标题: GWD-24-Q 22

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 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.

答案是C 没有看明白

这题是结论加强型题目
题干结论：it is a waste of money to order follow-up x-rays of ankle fracture initially judged stable.

为了证明follow up的确是浪费钱
只有C：不同医院里的不同医生的initial X-ray都被review过，证明initial X-ray的准确率很高，的确不用review，review是浪费钱（加强结论）
