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.

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。
