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 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 relining 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
答案是a
原文的意看懂了，可是这个a是什么意思啊，帮我讲讲里面的逻辑关系吧

A 的意思就是：没考虑到从本质上来说，surgical procedure 比其它以前有的最好的treatment对人还要有害。

意思我是懂，可能说真的，读题的时候就没看出它有flaw. 后来想了想，可能是因为前面是从本质上比较的，后面拓展到做手术的医生就不对了。

没理解，a对原文的逻辑好像没什么影响啊
拿来的flaw呢
bryony说的：后来想了想，可能是因为前面是从本质上比较的，后面拓展到做手术的医生就不对了。这些和a有什么关系呢

原文的理由是受外部因素医生的影响。

选项A：does not consider that new surgical procedures might be found to be intrinsically more harmful than the best treatment previously available ，即有一种内在的致命的错误，比任何以前的treatment都危险。提出了另一种可能“内在”因素。所以给出他因，对

the autuor cites clinical trial should not extend to surgical procedures because the success of surgical procedures depend on teh skills of the surgeons. however, if the procedures r intrinsically harmful, it will be bad no matter how skilled the surgeons may be. A strongly weekended the argument
