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.
不知道这是什么逻辑错误~

应该是选C

A说：疫苗不好
B说：有3家杂志说这个疫苗好
A说：因为疫苗不好，所以杂志有问题

说白了，A是“耍无赖”，他就永远假设疫苗不好，你无论如何反驳他，他的前提都是疫苗不好。

C选项说某种网球很好，因为他比其他的网球更effective（其实effective就是好的意思，他的推理就是，某种网球好，所以好。。。也是一种很“无赖”的推理）
