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?
Doctors who are general practitioners rather than orthopedists are less likely than orthopedists to judge the stability of an ankle fracture correctly.
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.
X-rays of patients of many different orthopedists working in several hospitals were reviewed.
The healing of ankle fractures that have been surgically repaired is always checked by means of a follow-up x-ray.
Orthopedists routinely order follow-up x-rays for fractures of bone other than ankle bones.
E选项：医生惯例为其他骨折开跟踪，而不是为踝骨折。 这难道不是加强了 为踝骨折开跟踪是浪费钱吗？
医生为其它的骨折开跟踪x-ray，这并不代表他们做的就是对的，当然也不代表他们就没浪费钱。反过来说，自然为踝关节开follow-up也不一定是浪费钱。
