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?

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 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?

A.      Doctors who are general practitioners rather than orthopedists are
        
less likely than orthopedists to judge the stability of an ankle fracture 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.

the OA is C

但是我不清楚怎么解释这两者之间的关系..为什么就加强了呢?

many thanks~!

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)
