请问OG130的D为什么不是答案？

carefield

你不贴题目, 我也懒得敲了.

逻辑关系: 联邦政府对银行存款的保险措施, 使银行的破产率增加, 原因是存款人懒得去发现银行是否安全可靠.

D: 不同银行的利率不是导致银行破产的重要原因.

D 所论述的不是在原题的逻辑关系内, ASSUMPTION 要求解释原题中的推理逻辑. SO D 是无关选项. 再不济, 可以把D 取非.

130. Bank depositors in US are all financially protected against bank failure because the government insures all individuals 's bank deposits . An economist argues that this insurance is partly responsible for the high rate of bank failure , since it removes from depositors any financial incentive to find out whether the bank that holds theri money is secure against failure . If depositros wre more selevive , then banks would need to be secure in order to compete for depositors's money.

assumtion.

E. Potentail depositors are able to determine which banks are secure agaisnt failure.

Answer E

iochiahsu

I am confused about why (E) is the correct answer?

While neglect choice (E) Potentail depositors are not able to determine which banks are secure agaisnt failure

I cannot lead to the conclusion that insurance is partly responsible for the high rate of bank failures

Am i mistaken the meaning of the economist's argument or what?

Please help me figure out of that!!!!!

Thanks a lot

still confused about the logic in 130. who can help me? thanks

这两个句子表达一样

这道题目在我脑子里面呆了一个晚上。看了一些讨论，有说D是支持，有说取非。怎么会是支持呢？取非？取非以后要说也是削弱，那么加上一个not，不是很标准的not+削弱的假设题目的答案吗？

我觉得问题是出在原文的 An economist argues that this insurance is partly responsible for the high rate of bank failure中的那个partly,说明原文并没有排除其他的原因，所以D排除其他原因起不到假设的作用。如果原文说的是一个唯一的原因，那么D应该是一个正确的假设的答案。

不知道我理解得对不对？这道题让我对not+削弱的支持答案有了一个比较深刻地认识。感觉很值得讨论讨论。

都懒得贴全题目，只能我来贴了。

130. 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.

我对这题的理解是D根本和题目没有多大关系。经济学家的推论是一直基于客户对银行的生存能力的判断上的。虽然我们的常识可以告诉我们利息率对银行有一定影响，但是这不是题目里面给出的东西。我觉得大多ＥＴＳ逻辑题不要我们自己去推测题目没有给出的条件。另外，Ｄ取非，并不能导致推论的不成立。Ｄ不是个假设。

我不同意你说的：虽然我们的常识可以告诉我们利息率对银行有一定影响，但是这不是题目里面给出的东西。

如果你有注意机考的题目的特点，你会发现assumption的题目，ETS现在更喜欢用not+削弱来作为假设，而不是像OG里面那么清晰的完全是文中内容的架桥。既然是削弱，那肯定可以出现文中根本没有提到的内容。即使是OG里面也有这样的例子，随便找一个：

A说：这个国家90%的人报告说他们认识的人中间有失业的，这是让人可怕的事情。

B说：但是，5%的失业率是正常的，也就是20个人中间有一个人失业。所以，在任何一个特定的时期内，如果一个人认识50个工人，其中就会有1个或更多的是失业的。

问：B的assumption是什么？

答案: unemployment is not normally concentrated in geographically isolated segments of the population（这里说的什么geographically isolated segments of the population文中根本没有提到，但是用常识判断就是一般说经济不发达，比较隔绝的地方，失业率会比较高）

欢迎继续讨论！

再来一个：

在Sicily的一个坟墓发现了一些瓷花瓶的样品，经过证实，这些样品实在Greece制造的。因为该坟墓埋葬的人死亡时期的统治者是在2700年前，花瓶的存在显示了在2700年前，Sicily和Greece之间有贸易往来。

答案：The vase that was found at the Sicilian tomb was not placed there many generations later by descendants of the occupant of the tomb.（这里的not后面所有的话都是文中根本没有提到的，但是用常识可以判断的）
