Complete Question Explanation

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

This is a classic ad hominem, or source argument. Instead of addressing the doctors' claim that the herbs are potentially harmful, the herbalist chose to attack the doctors themselves by stating that they are always trying to maintain a monopoly over medical therapies.

Answer Choice (A) There is no effort here to induce fear of the consequences of not trying the herbalist's herb juice. This answer choice would be correct if the herbalist had said something to the effect of "if you don't drink my juice, you'll die." No such claims were made in the stimulus, though, so this answer choice is incorrect.

Answer Choice (B) None of the claims in this stimulus are inconsistent with each other. Even the doctors' claim that the herbs in the herbalist's juice are potentially harmful is not inconsistent with the claim that the juice improves physical coordination in some customers. Something can be potentially harmful and still have positive effects, so these claims are not inconsistent with each other.

Answer Choice (C): This is the correct answer choice. This answer choice describes the source argument in the stimulus. The reason this technique is flawed is that, despite the fact that the doctors themselves have been attacked, we have no information to support or refute their assertion that the herbs in the herbalist's juice are harmful. Therefore, this is a flawed argument.

Answer Choice (D) Although the herbalist does seem to presuppose the truth of his assertion that there is no reason not to try his herb juice, there is an actual argument outside of any such presupposition. The problem is that one of the main premises is flawed as it ignores the argument and attacks those who are presenting the argument.

Answer Choice (E) There is no such mistake in this stimulus. The herbalist is using the fact that customers say their physical coordination improves after drinking the juice as support for the contention that people should drink the juice. The herbalist is not stating that because of this correlation, it is fact that the juice does improve coordination.

Hi Powerscore,

So, for this question.. I had it down between C and D. I initially wanted to pick "C" however, the wording was what threw me off. Specifically, the term proponents.... Since the stimulus states that a "few doctors assert that the herbs are potentially harmful" wouldn't those doctors that state that be considered opponents instead of proponents. I thought that this was a shell game choice.. Please tell me how I interpreted that claim incorrectly.

Hi Kdup,

Thanks for your question!

You are correct in saying that "proponents" means those who support or agree with something. You are also right that doctors would be considered opponents, not proponents of the herbal juices.

However, answer choice (C) says "rejects a claim by attacking proponents of a claim." So you need to determine what the claim is. According to the herbalist, doctors claim that the "herbs are potentially harmful." The herbalist rejects that claim by attacking doctors, who are the proponents of that claim.

Good luck with the rest of your studying!

Is answer choice D an example of "circular" reasoning?

Correct, blueballoon! That key is the use of the term "presupposes" in relation to the conclusion. Good eye!

For answer choice (E), if the Herbalist is not making a correlation vs causation flaw when herbalist said "many find physical coordination improvement after drinking it and there is no reason not to try the juice," then what kind of flaw is it?

Why would the herbalist share that information if the herbalist didn't think that the juice caused the physical coordination improvement?

Thank you!

Jay,

You must focus on the conclusion, which is the last sentence. The herbalist is not trying to convince us that the juice is beneficial! The conclusion is trying to say that it has nothing AGAINST it, not prove that it has anything FOR it. If the author had used the first sentence to show that the juice was positively beneficial, that would be different. But the author isn't doing that; in fact, the first sentence doesn't function as a premise of the argument at all.
