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

 

The economist's argument makes which of the following assumptions?

 

(A) Bank failures are caused when big borrowers default on loan repayments.

(B) A significant proportion of depositors maintain accounts at several different banks.

(C) The more a depositor has to deposit, the more careful he or she tends to be in selecting a bank.

(D) The difference in the interest rates paid to depositors by different banks is not a significant factor in bank failures.

(E) Potential depositors are able to determine which banks are secure against failure.

 

答案为E

以下是引用zsgc0011在2007-12-11 9:05:00的发言：

可是D选项不是取非完用它因削弱了么?

就算interest rate 是银行破产的一个重要因素

与文中所题的国家实行存款保险制度也没有关系啊

题目要削弱的是如果取消存款保险,存款者选银行的时候更挑剔一点,从而使银行更注重保证存款的安全

这里more selective不是对interest rate , but to security

同问 还是不明白D为什么错 多完美的取非削弱阿

我想啊，就算他是一个significant factor也不能证明保险不responsible,文中说“ this insurance is partly responsible ”，所以说的很清楚，就算给D取非也与原文不矛盾
