P335大全上的一道题

There is a great deal of geographical variation in the frequency of many surgical procedures—up to tenfold variation per hundred thousand between different areas in the numbers of hysterectomies, prostatectomies, and tonsillectomies.

To support a conclusion that much of the variation is due to unnecessary surgical procedures, it would be most important to establish which of the following?

(A) A local board of review at each hospital examines the records of every operation to determine whether the surgical procedure was necessary.
(B) The variation is unrelated to factors (other than the surgical procedures themselves) that influence the incidence of diseases for which surgery might be considered.
(C) There are several categories of surgical procedure (other than hysterectomies, prostatectomies, and tonsillectomies) that are often performed unnecessarily.
(D) For certain surgical procedures, it is difficult to determine after the operation whether the procedures were necessary or whether alternative treatment would have succeeded.
(E) With respect to how often they are performed unnecessarily, hysterectomies, prostatectomies, and tonsillectomies are representative of surgical procedures in general.

这道题完全没看明白。

没看懂是因为题目说手术地区上的不同导致手术步骤的频率的不同。结论, 这些频率的不同是因为手术上的步骤不同。不明白在说什么。

surgical procedure这个词的理解在这里不是强调"步骤"，而是surgical。这里surgical procedure = surgery

COnlusion的意思就是：地域手术频率的不同是由于 不必要手术的数量导致的。（不必要手术越多，地域手术频率越高；不必要手术越少，地域手术频率越少）

求近乎sufficient的assumption

B。 与手术无关的因素 不会导致 地域手术频率的不同（nearly sufficient assumption）。对。

哇，谢谢RRZZR。看了你第一句话就能明白题的意思了。
再次感觉到逻辑对关键词的精确理解的要求是很高的。
surgical procedure 看了一下其他词典，发现了一个“外科的処置”的意思。跟你说的差不多一样。

总体感觉本题还是挺好的一道题，毕竟，把结论放在问句里说的题很少见。
