Of patients over 65 years old who survived coronary bypass surgery—a procedure widely prescribed 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?



A. Many of the patients who receive coronary bypass surgery are less than 55 years old.

B. Possible benefits of coronary bypass surgery include both relief from troubling symptoms and prolongation of life.

C. Most of the patients in the survey decided to undergo coronary bypass surgery because they were advised that the surgery would reduce their risk of future heart attacks.

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, from the patients who did benefit.

答案居然是E，谁能解释一下呀！？感谢呀！

削弱题只能打断前提和结论之间的推理关系
题目：四分之一的老人没做手术——>医生出于锻炼技术和赚钱考虑,劝这些病人做手术,这些病人不能从手术中得益

这个题目的弱点很明显吧,谁没做手术,就是因为被医生搓骗,为了不上当不去做手术?

D选项说的是所有病人都得到了一样的通知,是加强,有些能做手术,有些不能,对他们进行一样的告知,不就更说明医生不是为病人着想,而是为了赚钱么

而E则指出,病人做了手术但是病情没有好转的情况,在手术前根本鉴别不出

那么就从他因来否定了结论,因为根本鉴别不出谁做手术有用谁没用,凭什么给医生抹黑?
结论也就不成立了
