The proposal to extend clinical trials, which are routinely used as systematic tests of pharmaceutical innovations, to new surgical procedures should not be implemented. The point is that surgical procedures differ in one important respect from medicinal drugs: a correctly prescribed drug depends for its effectiveness only on the drug's composition, whereas the effectiveness of even the most appropriate surgical procedure is transparently related to the skills of the surgeon who uses it.
The reasing is the argument is flawed because the argument
(A)does not consider that new surgical procedures might be found to be intrinsically more harmful than the best treatment previously available.
(B) ignores the possibility that the challenged proposal is deliberately crude in a way designed to elicit criticism to be used in refining the proposal.
(C) assumes that a surgeon's skills remain unchanged throughout the surgeon's professional life.
(D) describes a dissimilarity without citing any scientific evidence for the existence of that dissimilarity.
(E) rejects a proposal presumably advanced in good faith without acknowledging any such good faith

文章说因为临床和外科手术不一样，所以不能用临床方法测试外科手术。那么A怎么体现出flaw

analogy question,

the author believes that surgery and pill are not similar, and we want to weaken the author's argument, we sould argue that they are similar.

This is why A is correct, the pill is intrinsically dangerous (danger not depend on the skill of the doctors but itself ), so if so are some surgerise. then, these two things will be much more similar.

surgical procedure is related to skills, but it is not mentioned that surgical procedure depend only on skills.
A) New surgical procedures have intrinsic risks which can be removed by clinical trials.

Hope it is helpful
