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 fracture. 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?

请教GWD-24-Q22

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.

答案选C,我不明白C 是怎样起到加强作用的

请路过的NN 指点一下哈

脚踝骨折的病人如果被判断情况稳定通常不手术,但整形医生怕有对稳定性判断上的错误仍做X射线跟踪。一定数量的调查现实先前被判断稳定的病例全部正确愈合,所以X射线跟踪多余。问支持。

C是加强了调查的可信性,说X光片是从不同医院的不同整形医生那里取得的。这样从统计学上讲取样具有多样性,增强了结论的可信性。
