标题: 逻辑求救1 [打印本页]

有一逻辑题如下:
When limitations were in effect on nuclear-arms testing, people tended to save more of their money, but when nuclear-arms testing increased, people tended to spend more of their money. The perceived threat of nuclear catastrophe, therefoer, decreases the willingness of people to postpone consumption for the sake of saving money.

The argument above assumes that

(A) the perceived threat of nuclear catastrophe has increased over the years.
(B) most people support the development of nuclear arms.
(C) people's perception of the threat of nuclear catastrophe depends on the amount of nuclear-arms testing being done.
(D) the people who saved the most money when nuclear-arms testing was limited were the ones who support such limitations.
(E) there are more consumer gods available when nuclear-arms testing increases.

答案选C.
偶认为因为The perceived threat of nuclear catastrophe decreases the willingness of people to postpone consumption for the sake of saving money.则暗示着the perceived threat of nuclear catastrophe has increased.
为何A不对?
**偶也觉得C好象只是联系了threat of nuclear catastrophe和nuclear-arms testing.
请问如何作答?

论据:核试验增多,人们消费行为增多
结论:感觉到核危险,使人们减少为了储蓄而推迟消费,也就是增加消费
需要的桥梁:核试验的增多使人们感觉到核危险的增加(C)

A 是无关选项。
它没有在perception-----amount of nuclear-arms testing 之间打起桥梁。
原文的结构是这样的:
数量---消费
由此推出:perceived threat of nuclear catastrophe---消费。
在数量---?----消费。之间,缺的是什么?是桥梁:数量=perceived threat of nuclear catastrophe

条件:试验次数==>花费意愿
结论:感受威胁==>花费意愿
需要这样一个假设:感受威胁依赖试验次数,否则凭什么说感受威胁==>花费意愿
补充一句:这题是不是lsat,如果是,下次放到lsat专栏里,这样就比较集中。

哈哈,Kilroy,范进,分析思路清晰

至善!偶也觉得似乎C更对,只是找不到A错的原由!
这种状态上J场,怎么办?
备感CR薄弱! 敢问CR的复习方法.急!!! 偶下月考!!!

为了能象zyh79、kilroy一样肩上有颗金豆而努力奋斗!

a答案:感受威胁增加,那又怎样?
       能保证花费意愿增加吗?说不定还减少呢!
       不能带主观思考

“不能带主观思考”
经典!一语点中我逻辑思路的障碍!
谢谢先!
