Critical Reasoning

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 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 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

IMO A.

A says that the reasoning fails to consider the effectiveness of the surgery and instead only on the skill of the surgeon.

IMO C. Flaw in the argument is a first family question. So, the argument is true and the correct answer choice should be driven from the argument.

What is the OA?

IMO C

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.

Argument assumes that drugs are always prescribed correctly and that surgeon’s skills remain unchanged.

Divided between A and C.
In A...it says more harmful then previous method???? I don't like this hence choose C

I will go with C.

OA is A

If you have OE for this, pls post! Tx

I'm going with C. No confidence on my answer. Can anyone tell OA?
