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.

 

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

 

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

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

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

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

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

B感觉是加强啊，题干的意思是因为政府对存款提供了保险，所以储户不必自己寻找安全的银行，结果这些银行破产了。

    B                          的意思是在政府提供保险之前，由于储户对银行破产的害怕导致银行破产。
