大全-A-15

Alba: I don’t intend to vote for Senator Frank in the next election. She is not a strong supporter of the war against crime.

Tam: But Senator Frank sponsored the latest anticrime law passed by the Senate.

Alba: If Senator Frank sponsored it, it can’t be a very strong anticrime law.

Which of the following identifies the most serious logical flaw in Alba’s reasoning?

(A) The facts she presents do not support her conclusion that Senator Frank is soft on crime.

(B) She assumes without proof that crime is the most important issue in the upcoming election.

(C) She argues in a circle, using an unsupported assertion to dismiss conflicting evidence.

(D) She attacks Senator Frank on personal grounds rather than on he merit as a political leader.

(E) In deciding not to vote for Senator Frank, she fails to consider issues other than crime.

C中的argue in a circle应该怎样理解?

应该就是循环论证,用自己的一个尚未证明的假设,来作论据。也就是说,他的第二句话是基于他第一句话正确的基础上的,而第一句话也仅仅是他的一个assersion。

我的感觉是A在第二个论证的时候,有个假设She is not a strong supporter of the war against crime。所以A认为要是S支持的话结果就不一样了。这个好像是LSAT里面的题目,具体哪一题不记得了。
把所有的困苦都看做是有意义的,是生命对你的磨练,也许,是为了让你成大事而做准备。
