Just as a bicycle chain may be too tight, so may one’s carefulness and conscientiousness be so tense as to hinder the running of one’s mind.

24. Which one of the following, if true, would most seriously weaken the argument?

(A) Bicycle chains are used to turn wheels, but the human mind is used to “turn” ideas.

(B) People and bicycles are similar only in that both may not function well under stress.

(C) Bicycles help people with transportation, but careful, conscientious thought helps to solve many different problems.

(D) Extreme tension helps a bicycle chain to function efficiently.

(E) People engage in poor reasoning whether they are careful and conscientious or not.

the key: D. Why not C? In my opinion, C breaks the reasoning of the similarility between the bicycle chain and the brain.

(D) Extreme tension helps a bicycle chain to function efficiently.

(E) People engage in poor reasoning whether they are careful and conscientious or not.

the key: D. Why not C? In my opinion, C breaks the reasoning of the similarility between the bicycle chain and the brain.

这题是个比喻的题。它说自行车的车链太紧反而阻碍自行车的前进。那么人如果过份小

心和勤奋也会阻碍思想。D说自行车链过紧反而使之更有效,有削弱作用。C从逻辑上是破

坏了相似性,但是逻辑题削弱一般是削弱结论,不去削弱前提。

2楼的说法是错误的

论证逻辑既可以削弱前提,也可以削弱结论。

该题不被称为比喻题,逻辑学上无此称谓.

从论证结构上,该题为比较结构题

比较对象是People and bicycles

比较结论是so may one’s carefulness and conscientiousness be so tense as to hinder the running of one’s mind.

比较点是tight

该类型题,无论是问假设,支持,还是削弱,正确答案都应围绕比较点来说,因此只有一个选项,其他均为无关选项。
