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.

D. The difference in the interests rates paid to depositors by different banks is not a significant factor in bank failures.

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

Ans;E,我明白E是假设.

那么D呢?

有一题类似的:

OG.80
The program to control the entry of illegal drugs into the country was a failure in 1987. If the program had been successful , the wholesale price of most illegal drugs would not have dropped substantially in 1987.

assumption:
E.A drop in demand fro most illegal drugs in 1987 was not the sole cause of the drop in their wholesale price.

Ans:E

上一题的D与下一题的E有什么区别吗?为什么一个是假设,而另一个却不是呢?

谢谢.

看看第一个题目的D:. The difference in the interests rates paid to depositors by different banks is not a significant factor in bank failures.
注意它的用词， not a significant ,如果这个选项改成： D. The difference in the interests rates paid to depositors by different banks is not a sole fcator of bank failures.
那么D答案就是一个假设了，因为sole的存在排除了所有的他因，而significant不是所有的。第一个题目的D答案应该是个support.

对于assumption最有效的判断是取非：若将选项取非，结论不成立。则它必是assumption.

通常assumtion的三种答案模式：1。A, B 之间的联系 2。别的原因不导致B. 3. A成立或有意义。

OG130. “this insurance is partly responsible for the high rate of bank failure“ + "If depositros wre more selevive , then banks would need to be secure in order to compete for depositors's money.“

选项D: The difference in the interests rates is not a significant factor in bank failures

D看起来很像模式2，但是它并不是。取非后，模式2有排他性。"别的原因导致B"必然与"题中的原因导致了B"矛盾. 但是,"difference is a significant factor" 与 “government insurance partially cause bank failure" 并不矛盾。所以D不对，是一个混淆选项。多么狡猾的ETS阿！

OG80."The program to control the entry of illegal drugs into the country" -> "wholesale price of most illegal drugs would not have dropped"

E."A drop in demand for most illegal drugs was not the sole cause of the drop in price"

取非后，“A drop in demand is the only cause of the price drop" 与 "the program cause the price drop" 矛盾。因此， E是答案模式2。这里，“not the sole cause" 起到了强烈的限定作用。

说的真好，我是逻辑菜鸟，觉得这道题很绕。因为存款人不管银行的安全性，所以银行就不在乎自身的安全性，导致容易破产。而“存款人不管银行的安全性”是因为政府有insurance。E选项排除了“存款人不管银行的安全性”的一个原因：没有能力去选。所以只能是“政府有insurance”这个原因了。不知道这种思路对不对，请大虾们指点！

楼上的“没有能力去选。所以只能是“政府有insurance”这个原因了”这种思路有点问题。

E取非应该是：存款人没有能力区分银行的安全与否，也就无法选择银行，则银行同样也不会努力改善自身的安全性和竞争力，同样会failure，这个结果削弱了原文的结论。所以E是assumption。

lawyer_1 · 发表于 2006-3-31 23:22:00

这是充分必要型结论。选项取非是结论不能成立，因为结论是两个句子是必然的关系，所以选项取非后能够断开这个必然关系就可以，就是变成不是必然的关系就可以。不是让这个必然关系走向另一个必然关系。E 的作用就是这样。D是无关项。它在结论的两个句子间起不了任何作用。

选项Ｅ补全了原文结论推理链中的ｇａｐ，即：

推理链：depositors were more selective---〉depositors have the ability to determine-à banks would need to be secure in order to compete for depositors' money.

菜鸟问题: GAP 指由A=>B, 得到A=>C, 其中的GAP是B=>C, 题中需要三个元素.

而本题, 因为more selective=> secure只有两个元素, 怎么是个GAP呢?

sigrid920 · 发表于 2006-7-27 04:41:00

还有一个疑问:

OG10-63: 高层经理比中低层经理更多使用直觉 (现象前提)

直觉更有效 (推测)

我明白这题的答案方向是架桥, 但是不明白的是, 既然OG130 的假设是(E)存款人有能力分辨哪个银行更安全, 为什么这题OG63 就不能选(B)高层经理有能力使用直觉或老方法, 若高层经理都没有能力用这些方法,又怎么谈效率呢?

盼大牛指点

kdjd · 发表于 2006-7-27 12:37:00

B不是assumption啊。文中的study已经表明他们在用intuitive reasoning，即有能力，所以不用考虑有没有ability的问题。

而这道题里面If depositros wre more selevive不代表Potentail depositors are able to determine which banks are secure agaisnt failure。

我是这么理解的～
