The proposal to extend clinical trials, which are routinely [#permalink]
 04 Jan 2004, 20:39
Question Stats:
0% (00:00) correct
 0% (00:00) wrong based on 0 sessions
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 .

A is best.
surgical procedures may have inherent risks which are not dependent of the skill of the surgeon

The answer is A. I am sure Geethu will come with a great explaination.
I chose C. Here is my logic
The argument talks about the new surgical method. If surgeon's skill does not remain same then even the old surgeries will have different results. Since old surgical methods are still employed ( I assumed it )and successfull the dependency on the variation of surgeons skill is minimal. The argument assumes too much about the surgeon's skill.

As per my understanding.
The argument says clinical trials should not be extended to surgical procedures as they depend on the surgeons skills which can not be measured like the drug composition. But A says there could be other better treatments than surgery. In this case the surgeons are to be blamed irrespective of their skills.

Hi Geethu,
Authors holds surgeon's skill as an important factor in the effectivemess of the new surgical procedure. We have to prove that authors reasoning is flawed. We either show that surgeon's skill does not matter very much or the new surgical method are better than any existing treatment. I dont understand how A brings out the flaw in the authors reasoning.
Now I am begining to think that C and A are almost same.
Please explain further by disecting the argument and what is expected.
Thanks in advance.
