Question ID:PT11 S4 Q19 Passage: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. Stem:The reasoning in the argument is flawed because the argument Correct Answer Choice:AChoice A:does not consider that new surgical procedures might be found to be intrinsically more harmful than the best treatment previously available Choice 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 Choice C:assumes that a surgeon’s skills remain unchanged throughout the surgeon’s professional life Choice D:describes a dissimilarity without citing any scientific evidence for the existence of that dissimilarity Choice E:rejects a proposal presumably advanced in good faith without acknowledging any such good faith
