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?
这道题我关注的是economist的观点，即这个insurance导致failures，然后D选项说的是利率高低不影响failure，然后我就理解成排除他因，所以选了，求老师指出错误的点
