大全GMAT TestC-14?

Rayakawr

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.

题目是说Dr.A认为vaccine不行。Dr.B认为studies表明Vaccine可行。但Dr.A坚持认为Vaccine不行，进而否定Studies。

答案给的是C.C的推理过程怎么会与Dr.A的最相似呢?难道只是因为两者都是先入为主的观点？

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。

A教授认为疫苗是无用的，B教授说发表在某个杂志的研究证明是有效的，A教授说因为疫苗本身是无用的，所以他不相信那个研究报道哦。

嫱嫱

题目中，A教授的意思是说，既然我认为疫苗本身本来就是无用的，那么基于这个无用疫苗的研究更是不可信的。
B的意思是，我不相信J，既然J推荐我喝牛奶，那么我必然也不会相信牛奶

c就是球队表现得好，就是因为他们比别的球队有效率，
