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 number 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 succeded.
E) With respect to how how often they are performed unnecessarily, hysterectomies, prostatectomies, and tonsillectomies are representative of surgical procedures in general.
OA after discussion.

C is the answer.
A--irrelevant to the arguement.
B--weakens the arguement, rather than supporting it.
C--correct answer. Supports the arguement that there are many procedures that are unnecessarily performed, and not just tonsilectomy, pros......
D--weakens the arguement.
E--three surgical procedures cannot represent entirety of surgical procedures.

Should be B
A) - Doesnt answer question variation is associated yo unncessacry surg. procedure
B) Could be. try to negate and u can find the impact
C) so what?
D) doesnt answer the actual root question
E) Irrelevant

I would go for E...
Premise is that there is great deal of variation in SP.....
Conclusion is that surgical procedures are unnecessary and we have to find an answer that can provide that informaiton....
E hits the spot....if we can detmrine the ratio we can show that SP are un-necessary

IMO B.
The argument to be supported is Surgeries were not required.
A) - review which tells u it was necessary or not. Does not support the argument.
B) Variations is not related to factors causing diseases.
So this helps to state that surgeries were not required.
C) out of scope
D) out of scope
E) again out of scope.
Hope this helps.
