Complete Question Explanation

Flaw in the Reasoning. The correct answer choice is (C)

Anna quotes an ancient Roman scholar who claimed that rainbows always occur opposite the sun.
William finds the scholar’s claims to be false. His reasoning is that the same scholar made several
other assertions that are clearly false.

William’s counterargument contains a logical flaw. Just because the scholar in question was not
always correct does not mean that his claims about rainbows are also incorrect.

Answer choice (A): William does not distort Anna’s conclusion; he merely disagrees with it. The
flaw in his reasoning is not a Straw Man.

Answer choice (B): William does not assume that the Roman scholar was in bad faith when making
incorrect assertions. This is a Source argument, for which there is no evidence here.

Answer choice (C): This is the correct answer choice. Just because some of the Roman scholar’s
assertions are provably false does not mean that his claims about rainbows are also false.

Answer choice (D): William does not accept the ancient Roman scholar’s claims; on the contrary—
he rejects them.

Answer choice (E): There is no evidence suggesting that William would view the scholar’s claims as
outdated. This answer choice falls entirely outside the scope of William’s counterargument.

Hello, even if it were happening in the stimulus, would Answer choice D even describe a flaw or is it not a flaw at all? (accepts the assertions of an ancient scholar without presenting contemporary verification of that scholar's views)

Hi SDG,

It's possible that could be a flaw, but it doesn't really make sense here. As the administrator pointed out, William actually rejects the claim entirely by saying that the person who made it is unreliable. Putting that aside, how rainbows occur in the sky is not something that we would expect to change over time. If Pliny the Elder's method for coming to that conclusion was iron clad, it might be fine to accept it as true. On the other hand if the claim was about something that could have changed over time, it could absolutely be a flaw to say that there was no contemporary verification.

Hope that helps!
Beth
