标题: 老prep 2 59 关于他因削弱和无关之间的界限

59. (33759-!-item-!-188;#058&007597)

Bankdepositors in the United States are all financially protected against bankfailure because the government insures all individuals' bank deposits. An economist argues that this insurance ispartly responsible for the high rate of bank failures, since it removes fromdepositors any financial incentive to find out whether the bank that holds theirmoney is secure against failure. Ifdepositors were more selective, then banks would need to be secure in order tocompete for depositors' money.

Whichof the following, if true, most seriously weakens the economist's argument?

(A)Before the government started to insure depositors against bank failure, therewas a lower rate of bank failure than there is now.

(B)When the government did not insure deposits, frequent bank failures occurred asa result of depositors' fears of losing money in bank failures.

(C)Surveys show that a significant proportion of depositors are aware that theirdeposits are insured by the government.

(D)There is an upper limit on the amount of an individual's deposit that thegovernment will insure, but very few individuals' deposits exceed this limit.

(E)The security of a bank against failure depends on the percentage of its assetsthat are loaned out and also on how much risk its loans involve.

我选了E.答案是B。

B我现在明白了。

请问E为什么不能算是他因削弱呢？不是说削弱题可以出现和题干没有的新信息吗？要怎么区分他因削弱和无关呢？

What E describes is the necessary condition for a bank to secure against failure. It has nothing to do with WHO should pay for such service or whether a depositor should pay attention to such service. Thus, E is irrelevant to the author's argument.
