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.

没有看懂题意  不明白为什么选E,请帮分析一下,谢谢!

题目的意思是：美国政府为所有存款人提供银行破产的存款赔偿是造成银行存在很高破产率的部分原因，因为这一措施使得存款人不再考虑他们将钱存入的银行是否会破产。如果存款人能够更具选择性，银行便需要在竞争中提高自身的安全。

E说潜在的存款人能够决定哪个银行更不容易破产，就是说他们能够selective更安全的银行，这样便能提高银行间的竞争，所以是argument的前提。

请问这题为何c选项不可?!

C的意思是“depositor”存的越多，他们越关心银行的选择，但是文中的意思是，作者建议depositor更主动的去选择，也就是说人们不是很主动的关心银行的选择，C和作者的意思是矛盾的，所以不是前提。

我前面也错选了C


实际上文中的最后一句，If depositors were more selective, then banks would need to be secure in order to compete for depositors' money.

是作者的结论，对E取非，显然是weaken结论的，所以E对。
