※ 引述《denizee3 (妮)》之铭言： : Often patients with ankle fractures that are stable, and thus do not require : surgery, are given follow-up x-ray 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 原文这里说 a number of ... 被 reviewed，发现这些被复检过的「通通都是」... (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. 所以，推论出 it is a ... judged stable. 而这推论中的 ankle fracture 是指 所有的状况，不仅只是之前被复检过的。 因此，这段推理犯了「归纳」错误。（以部分推全部，但这「部分」不一定具代表性。 : 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. 答案 C说，这些被 reviewed 的病例，来自不同医院，不同医生，也就是这些被 reviewed 的病例，并非偏颇取样的结果。所以「具备代表性」，可以用来「归纳」 出全部病例也都会如此。 总结来说，答案C是归纳支持答案。 以上，供参考。 : 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. : Answer: C : 我选B, 看了伤咖的文章可以了解B为什麽错.. : 但是还是不能了解为什麽答案是C : 是否可以请大家帮我解释一下! : 谢谢! --
