This argument depends on the assumption that skill level of a doctor is inversely proportional to recuperation time taken by patients i.e Low recup time = High skill and vice versa.
To weaken this argument, we have to attack this assumption and show that abovementioned relationship does not hold true.
A) Dr. Roark’s patients tend to require fewer procedures than those of other doctors in the hospital - We dont make any assumption regarding procedures performed; Also we dont know how number of procedures is linked to doctors skill. WRONG.
B) The recuperation required after a given surgery can vary significantly based on the skill level of the doctor who performed the surgery - This is exactly the assumption we stated. BUT, this strengthens the argument, not weakens. Thus WRONG.
C) Dr. Roark has been associated with Oceanside for three years longer than than any other surgeon in the hospital - Association with oceanside has nothing to do with skill level. What if more experienced and skilled surgeons exist but they are associated for 1 year only. Thus WRONG
D) Operations which require less skill tend to require shorter periods of post-operation recuperation - This says that patients of other doctors recuperate faster because they undergo surgeries which require less skill. Indirectly, Dr Roark performs work with more skill. CORRECT
E) Dr. Roark has operated on two other doctors at Oceanside - Irrelevant. WRONG.
