There is a great deal of geographical variation in the frequency of many surgical procedures-up to tenfold variation per hundred thousand people among different areas in the numbers of hysterectomies，prostatectomies，and tonsillectomies.
谢谢大家！

原题目如下：
There is a great deal of geographical variation in the frequency of many surgical procedures-up to tenfold variation per hundred thousand people among 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．
在许多频繁外科后续程序中存在大量的地区差异，在子宫切除、前列腺切除、扁桃腺切除术当中，不同的地区每10，000人存在10倍的不同。
这是偶硬着头皮翻译的，可就是不明白说什么呢,汗。what's the procedures-up ? and,what is the procedures-up point to?
前辈们，给指点一下。这道题，我都想了一天了
偶的问题很弱智吗，哪位前辈给分析一下
