Dr. A: The new influenza vaccine is useless at best and possibly dangerous. I would never use it on a patient.
Dr. B: But three studies published in the Journal of Medical Associates have rated that vaccine as unusually effective.
Dr. A: The studies must have been faulty because the vaccine is worthless.

In which of the following is the reasoning most similar to that of Dr. A?

(A) Three of my patients have been harmed by that vaccine during the past three weeks, so the vaccine is unsafe.
(B) Jerrold Jersey recommends this milk, and I donâ€™t trust Jerrold Jersey, so I wonâ€™t buy this milk.
(C) Wingzz tennis balls perform best because they are far more effective than any other tennis balls.
(D) Iâ€™m buying Vim Vitamins. Doctors recommend them more often than they recommend any other vitamins, so Vim Vitamins must be good.
(E) Since University of Muldoon graduates score about 20 percent higher than average on the GMAT, Sheila Lee, a University of Muldoon graduate, will score about 20 percent higher than average when she takes the GMAT.

Ahh logical fallacies. I love these. Understanding the common types will help not only the CR questions, but also your AWA Analysis of Argument essay.

I like C. A's reasoning similar to option C

It's a Circular argument.

Dr A argues that the vaccine is worthless because it doesnt work and is dangerous. Dr A is basing the worth on how effective the vaccine is. i think this is closest to (C)????

WOW. this one is not that clear to me even after staring at it for minutes.

debating between B and C.
But will go for C.

My reasoning :
Vaccine useless. Study faulty as vaccine useless.
Tennis balls best. Bacause a lot better than others.

OA is C. For more explanations see http://www.gmatclub.com/phpbb/viewtopic.php?t=34973

Some related questions.

What is the source of the 'circular argument' reasoning?
IS there a book that details all types of logical fallacies?

I currently follow princeton verbal for CR. Obviously there is a better book out there somewhere.
