Complete Question Explanation
Flaw in the reasoning. The correct answer choice is (A)
The stimulus argues that the true scientific significance of some fossils is likely to be reflected in a more recent classification rather than Walcott's own classification. This assertion is supported by pointing to who Walcott was—a prominent member of the scientific establishment. Thus, the argument infers that Walcott, on the basis of who he was, probably set out to confirm what established science had already taken to be true—missing the true scientific significance of these fossils.
Answer choice (A): This is the correct answer choice. The argument's attack on Walcott's classification of the fossils is based entirely upon who Walcott was. Thus, draws its conclusion about a position from the characteristics of the source of that position.
Answer choice (B) The argument does not cite two pieces of evidence. The one piece of evidence the argument cites is about who Walcott was. The rest of the argument are inferences drawn from who Walcott was.
Answer choice (C) There is no contradiction in the argument between two premises. The two premises that support the main conclusion in this argument—one piece of evidence about Walcott, and one inference drawn from that evidence—are perfectly consistent. The flaw is that the inference is based upon who Walcott was—not that it contradicts the evidence from which it is drawn. Furthermore, there is no indication that the terms used are vague.
Answer choice (D) The argument does no such thing. There is no opposite claim mentioned or attacked.
Answer choice (E) There is no indication that the social and political categories the argument uses—member of the scientific establishment—applies only to the present and not the past.
