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.

We are looking for a AC which can tell us that the doctors were not aware that on which patient the surgery will be successful or not, because (E) says that the doctors did not know it so it weakens the argument that the doctors knowingly performed surgeries to earn money even though they knew that the patient will not survive.

(D)is out of scope ; we do not know that one out of 4 died patients were aged more than 65 or not.

D and E are close.....APPLY SO WHAT CHECK.....

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. SO WHAT...INFORMING ALL ABOUT RISK OF SURGERY PROVES NOTHING....EVEN IF THEY DID NOT INFORM, the doctors who advised them to undergo this surgery COULD HAVE BEEN more interested in an opportunity to practice their skills and in their fee than in helping the patient.
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.
SO WHAT... the doctors who advised them to undergo this surgery COULD NOT HAVE KNOWINGLY ACCEPTED ONE BAD CONDITION PATIENT to practice their skills and earn fee. SINCE ALL WERE ALIKE WE CANT SAY ONE WAS CHOSEN TO MAKE MONEY............
