Of patients over 65 years old who survived coronary bypass surgery-a procedure widely proscribed for people with heart disease-only 75 percent benefited from the surgery. Thus it appears that for one in four such patients, the doctors who advised them to undergo this surgery, with its attendant risks and expense, were more interested in an opportunity to practice their skills and in their fee than in helping the patient.
Which of the following, if true, most seriously undermines the argument?
D the patients over 65 years old who did not benefit from the coronary bypass surgery were as fully informed as those who did benefit from the surgery as to the risks of the surgery prior to undergoing it.
E. the patients who underwent coronary bypass surgery but who did not benefit from it were medically indistinguishable, prior to their surgery, form the patients who did benefit.
答案是E，可我觉得E是无关项，医学上区分不了谁适合谁不适合，跟医生的想法是无关呢。
我觉得只要证明医生没那么坏就可以了，D讲到医生已经把风险告诉了患者，所以说明医生不是为了自己的利益建议患者做手术。
是不是我的想法有点奇怪，所以更要请大家赶紧给我纠正～～～～谢谢啦！
原文的结论是：医生想用那些不应做手术的人做实验。
前提就应该是，医生得知道哪些人应该做，哪些人不该做。也就是说，如果医生分不清谁该做，谁不该做，就不可能产生以上结论。
D选项，医生对所有病人都告知了手术预期情况。这不影响医生对那些不该做手术的人持有恶毒想法的可能。
这么想还真是～～～谢谢呢。
