19. 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 drugâ€™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 reasoning in 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 surgeonâ€™s skills remain unchanged throughout the surgeonâ€™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
A seems fine...the proposal should not be dismissed as it could have a useful purpose (i.e. if a new procedure is harmful).
I dont even understand B and E in this context.
C is irrelevant because they dont mention anything about a surgeon's skills changing or not changing but just that a particular surgeon might not be skilled.
D is a bit tempting because there is dissimilarity mentioned but the reason given for it seems valid...not a hollow statement without any support
If the trials cannot be extended to surgical procedures only because of the surgeon's skills then the argument is flawed because it is assuming that the surgeons skills remains same throughout his professional life.
