标题: 请教GMAT大全里的一题

14.   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.

答案C请问这种题的解题思路是什么?

perform best=effective

worthless=faulty

就好象是说“因为你错了,所以你错了”根本没有给出证据,主观臆断

这道题问的是 circular reasoning ”循环论证“ 一种逻辑错误

具体解释可参照以下链接,简而言之就是,”The conclusion is already taken to be true in the initial argument, so we can see it is is also an example of circular reasoning.“
