※ 引述《Stumas (Fenway Park)》之铭言： : [CR] 请问一题 CR : 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? : 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. : 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. : (OA防雷) : 答案 (C)，但我怎麽看好像跟题目都没关联性啊，有人可以解释吗? 这题最近正好有两个同学问我 题目意思是: 骨折病人被诊断恢复正常的， 经过 X-Ray 进一步诊断之後，也是一样正常的情形。 所以 X-Ray 是没必要 (浪费钱) 的。 (C) X-Ray 的检查包含了许多不同医院的骨科医生的报告 --> 此答案说明了题目样本范围是广大的，说明样本的客观性 而不是局限在少数或特殊的几个 case 里面 -- Donz GMAT 6~7 月实力班: http://www.donzgmat.com/course-5weeks Donz GMAT FB: https://www.facebook.com/groups/DonzGMAT Donz 全科线上机经课: http://ndxica.pixnet.net/blog/post/41525434 --
