著名的因果錯置題
137. A study of marital relationships in which one partner's sleeping and waking cycles differ from those of the other partner reveals that such couples share fewer activities with each other and have more violent arguments than do couples in a relationship in which both partners follow the same sleeping and waking patterns. Thus, mismatched sleeping and waking cycles can seriously jeopardize a marriage.
Which of the following, if true, most seriously weakens the argument above?
(A) Married couples in which both spouses follow the same sleeping and waking patterns also occasionally have arguments than can jeopardize the couple's marriage.
(B) The sleeping and waking cycles of individuals tend to vary from season to season.
(C) The individuals who have sleeping and waking cycles that differ significantly from those of their spouses tend to argue little with colleagues at work.
(D) People in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle from that of their spouses.
(E) According to a recent study, most people's sleeping and waking cycles can be controlled and modified easily.
解答137.
The argument assumes that mismatched sleeping and waking cycles precede martial problems. Choice D weakens the argument by indicating that this assumption is false, and D is the best answer.
The argument does not depend on there being only one cause of marital problems, so choice A is incorrect. That sleeping and waking cycles can change seasonally or might not affect interactions with colleagues does not address the issue of how mismatched cycles between spouses affect their marriage, so B and C are incorrect. Choice E suggests that there is a way to test the conclusion-by brining a couple’s sleeping and waking cycles into alignment-but this by itself does not weaken the argument, so E is incorrect.
