大全GMAT TestC-14?

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.

你说得很对啊，就是根据结论推定原因的方式。

A是由于反面例证而推定，一朝被蛇咬十年怕井绳
B是由人及事，坏人一定不会有好建议
D是随大流从众判断，用得多就好，要不怎么会大家都用呢
E是拿普遍当个别

只有C是先肯定结果进而肯定原因，和先否定结果因此否定原因是一种思维方式。

解释的好清楚啊！
