标题: 请教一道逻辑大全-C-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.

(D) I’m buying Vim Vitamins. Doctors recommend them more often than they recommend any other vitamins, so Vim Vitamins must be good.（C）

(E) Since laceType>UniversitylaceType> of laceName>MuldoonlaceName> graduates score about 20 percent higher than average on the GMAT, Sheila Lee, a laceType>UniversitylaceType> of laceName>MuldoonlaceName> graduate, will score about 20 percent higher than average when she takes the GMAT.

The answer is C, the reasoning pattern is "begging the question", or "循环论证"。

这是用PREASSUME的结论做为论证的论据

好象考试的时候不会遇到这种题，这是典型的LAST题目。

以下是引用dorbear在2004-2-15 11:27:00的发言：
The answer is C, the reasoning pattern is "begging the question", or "循环论证"。

求教一下：怎么看出C就是循环论证呢？怎么排除其他的选项呢？
