※ 引述《denizee3 (妮)》之銘言:
: 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
原文這裡說 a number of ... 被 reviewed,發現這些被複檢過的「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,推論出 it is a ... judged stable. 而這推論中的 ankle fracture 是指
所有的狀況,不僅只是之前被複檢過的。
因此,這段推理犯了「歸納」錯誤。(以部分推全部,但這「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說,這些被 reviewed 的病例,來自不同醫院,不同醫生,也就是這些被
reviewed 的病例,並非偏頗取樣的結果。所以「具備代表性」,可以用來「歸納」
出全部病例也都會如此。
總結來說,答案C是歸納支持答案。
以上,供參考。
: 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
: 我選B, 看了傷咖的文章可以了解B為什麼錯..
: 但是還是不能了解為什麼答案是C
: 是否可以請大家幫我解釋一下!
: 謝謝!
