### HideShow timer Statistics

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 don’t trust Jerrold Jersey, so I won’t buy this milk.

(C) Wingzz tennis balls perform best because they are far more effective than any other tennis balls.

(D) I’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.

What is strategy to solve this kind of question?

I think its B.
Because of prior belief about a vaccine,the author refutes the claim of the studies.
In a similar way,author refutes a claim as in B by attacking the character of Jersey.

C for me.

Dr A does not give any reason for his belief.

similarly C also does not give any reason.

in other choices there is some logical reasoning.

Here we r not comparing with the other method we r proving our method as the best even contradicting others so (B) should be the answer.
