GWD7-Q17:   weaken
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.
答案是E哎~我都没有看懂这个选项是什么意思？尤其是 medically indistinguishable？？太晕了~所以请大家帮帮忙~

这里medically indistinguishable要表达的意思是这些没有受益的病人的病情与其他受益的病人是没有区别的，言下之意就是医生之前并不知道他们并无法受益于这个手术。因此阴谋论不成立，只是这些病人运气不好而已，医生确实是想治好每一个病人，而不是只为了练手机会和手术费。
