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.
答案是E。我认为D也可以做假设啊，D否定了其他可能的原因啊，所以也相当于假设了。-- by 会员 Christianyang (2010/9/20 10:59:39)
this insurance is partly responsible for the high rate of bank failures 一定程度上认为是insurance的原因却并没有否定 The difference interest rates paid to depositors 不是一个关键因素
你同意D就好像下面这个逻辑："我认为A很重要。"你得出我的假设是"我认为B不重要"

我知道E对。新东方老师给假设题的思路是否定可以削弱的原因，我就选了D了。我现在认为问题是出在那个significant上，取非的话不能完全否定。
