LSAT6-IV-22问题请教

22. The true scientific significance of a group of unusual fossils discovered by the paleontologist Charles Walcott is more likely to be reflected in a recent classification than it was in Walcott's own classification, Walcott was, after all, a prominent member of the scientific establishment. His classifications are thus unlikely to have done anything but confirm what established science had already taken to be true.
Which one of the following most accurately describes a questionable technique used in the argument?
(A) It draws conclusions about the merit of a position and about the content of that position from evidence about the position's source.
(B) It cites two prices of evidence, each of which is both questionable and unverifiable, and uses this evidence to support its conclusions.
(C) It bases a conclusion on two premises that contradict each other and minimizes this contradiction by the vagueness of the terms employed.
(D) It attempts to establish the validity of a claim, which is otherwise unsupported, by denying the truth of the opposite of that claim.
(E) It analyzes the past on the basis of social and political categories that properly apply only to the present and uses the results of this analysis to support its conclusion.
Answer: A
为什么是Ａ？

passage mentioned "a true significient scientific discovery" and then mentioned "was reflected" more of discovery of somebody else rather than that of Walcott's own. In the last sentence, the author inferred that Walcott's discovery is not important(has not done anything but confirmed...).

one of the questionable techniques at issue is not to evaluate the discovery on the discovery itself but on its source. that's what answer A says.

one of the similiar mistakes is to criticize the personality of a position instead of the position itself.

hope it will be of some help.

我想弱弱地问问：A选项的position是不是conclusion的意思啊！这种抽象词语怎么把握

看看我的这个问题

这个position的意思是见解，看法。
在这里我觉得就是对classification的看法。这篇文章讲的使用什么样的classification更有意义。它指出有author自己的classification是源自。。。，从而得出这个classificaiton怎么好怎么不好。所以它之说了source,而没有讲classification自己
