标题: One more GWD question

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

Why C? I think both C and E make sense. However, E may be the one most strengthern the argument.
