求助各位大虾，一道应该比较老的逻辑题了：
Ofpatients over 65 years old who survived coronary bypass surgery—a procedurewidely prescribed for people with heart disease—only 75 percent benefited fromthe surgery. Thus it appears that forone in four such patients, the doctors who advised them to undergo thissurgery, with its attendant risks and expense, were more interested in anopportunity to practice their skills and in their fee than in helping thepatient.
Which ofthe following, if true, most seriously undermines the argument?

A. Many of the patients who receive coronarybypass surgery are less than 55 years old.
B. Possible benefits of coronary bypass surgeryinclude both relief from troubling symptoms and prolongation of life.
C. Most of the patients in the survey decidedto undergo coronary bypass surgery because they were advised that the surgerywould reduce their risk of future heart attacks.
D. The patients over 65 years old who did notbenefit from the coronary bypass surgery were as fully informed as those whodid benefit from the surgery as to the risks of the surgery prior to undergoingit.
E. The patients who underwentcoronary bypass surgery but who did not benefit from it were medicallyindistinguishable, prior to their surgery, from the patients who did benefit.
为什么答案不是D呢？医生在手术前告知患者手术的风险不是能削弱医生“唯利是图”的论证吗？而答案E患者能否被辨别与医生的“唯利是图”有什么关系？
谢谢各位指点啊！！我7月14就考试了，心情比较急切..

我第一次做这个题的时候也有这个疑问，但老师将的是，这个题关键在于indistinguishable，如果4个病人有一个病人医生在手术之前不确定是否能成功，但其余3个医生可以确定一定成功，那么即使医生告诉病人所承担的风险一样，也是没用的，问题是如果所有的病人在手术之前都不确定手术是否成功，医生都是抱着试一试去帮助病人的态度，那么即使手术失败，也能说明医生其实是想帮病人的

D 很明显无关。
