Armstrong: For the treatment of a particular disease, Dr. Sullivan argues for using nutritional supplements rather than the pharrnaceuticals that most doctors prescribe. But this is in his self-interest since he is paid to endorse a line of nutritional supplements. Thus, we should not use nutritional supplements in treating the disease.

Armstrong's argument is flawed in that it

A. relies on two different meanings of the term "supplement" to draw a conclusion

B. relies solely on an appeal to an authority whose trustworthiness should not necessarily be taken for granted

C. appeals to people's emotions regarding the treatment of disease rather than to the efficacy of the two approaches to treatment

D. criticizes Dr. Sullivan's motives for holding a position rather than addressing the position itself

E.. fails to justify its presumption that nutritional supplements cannot be used in conjunction with other treatments

KUDOS will be Appreciated

Armstrong initially attacks Dr S method and there after attaches his personal motive to that method.
So he does not attack the shortcomings of the method but involves personal motive to the method.

D gives the exact reasoning

Hi Chetan2u,
Can you please explain option D again. Armstrong did not initially attack Dr. Sullivan's method. He found a reason that since personal motives are involved, w cant trust Dr. Sulivan.
Option D states that- D. criticizes Dr. Sullivan's motives for holding a position rather than addressing the position itself
I think the flaw is Armstrong's method of reasoning to dismiss Sulivan's claim. Armstrong does not need to address the position whether nutritional supplements are better than the pharrnaceutical supplements. His logic of reasoning to dismiss Sulivan's claim is wrong.

If you break down this argument:

Sentence 1 is background information telling us that this doctor recommends supplements.

Sentence 2 is the evidence for the conclusion: the doctor is acting in self interest! Notice, too, that the supplements aren't mentioned here...just the doctor.

Sentence 3 is the conclusion: therefore, we shouldn't use these supplements.

So if we're looking for a flaw in reasoning, it has to do with Sentence 2, or how 2 interacts with 3.

Look at what's missing between 2 and 3 - the only piece of evidence for "don't use the supplements" is "the doctor acts in self-interest." The major premise never mentions the supplements! All it does is mention how the doctor is motivated. And that's the flaw: the conclusion says that you shouldn't use supplements, but its only evidence is about the motives of one person who recommends the supplements - we don't have any evidence that the supplements are ineffective (or bad for any other reason). And that's what D tells us.
