标题: 求助OG verbal review 45 [打印本页] 作者: dickyjoke 时间: 2010-9-21 16:54 标题: 求助OG verbal review 45 ofthen 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 dudged stable were found to have healed correctly. therefore, it is a waste of money to order follow-up x-rays of ankle fractures 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-rays 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 bones other than ankle bones.

原文说When number of follow-up x-rays were reviewed...，没有说明选择的样本是否能代表全部。而C说样本是取自many different orthopedists working in several hospitals，说明了样本的代表性，加强结论。作者: dickyjoke 时间: 2010-9-21 19:31
