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.
这个题目看上去很像因果论证的模式，所以D选项很容易在思路不清楚的情况下误选，但是对D 取非会发现D无法削弱原文结论。
所以我想问一下，这个题目是因果论证？还是不是？
麻烦说一下你区分是否因果论证的思路。万分万分感谢！！！
看了你的帖子很是受益，一遍遍的看过做过的题目，似乎比以前有所领悟了，希望某一天能够彻底顿悟。 |
