[求助]陈向东逻辑假设47

Exports of United States wood pulp will rise considerably during this year. The reason for the rise is that the falling value of the dollar will make it cheaper for paper manufacturers in Japan and Western Europe to buy American wood pulp than to get it from any other source.

Which of the following is an assumption made in drawing the conclusion above?

A.      Factory output of paper products in Japan and Western Europe will increase sharply during this year.

B.      The quality of the wood pulp produced in the United States would be adequate for the purposes of Japanese and Western European paper manufacturers.

C.      Paper manufacturers in Japan and Western Europe would prefer to use wood pulp produced in the United States if cost were not a factor.

D.     Demand for paper products made in Japan and Western Europe will not increase sharply during this year.

E.      Production of wood pulp by United States companies will not increase sharply during this year.

answer:B

我把Ｂ取非，看不出是怎样削弱了原文．我做题选的是Ｄ，取非后我认为是给出了他因，即不是便宜导致出口上涨，而是需求大了．但再看了各位前辈的有关无关贴，又绕进去觉得是无关～

请大家帮忙一起看看～我的问题在哪里．

另外，我先开始看假设，错误率很高，但之后开始做削弱加强，几乎没有碰到什么困难．好奇怪～我到底该怎么继续复习呢？谢谢～～～

如果是D的话，说其他国家对纸产品需求量不会大幅上升，那他们就有可能不买美国的产品啊，怎么是假设呢，it appeas to be somewhat weaking .

哦，我明白了。是我没有看清楚介词~但是为什么是B我还是不太懂~

能不能分析一下这里假设的思路？

我觉得把Ｂ取非，削弱的是：the falling value of the dollar will make it cheaper ,这不是题目的事实前提么？

混乱中……

MM,我不知道你是不是上了什么名师的课程，所以一定要在做assumption题的时候去取非，

我不知道这种方法到底好在哪里，因为我觉得这样取非浪费了大量不必要的时间。

至于B，如果你一定要取非，那意思就变成，

美国已经不能满足其他国家对纸的质量要求，那美国不是做不成出口的纸浆生意了吗？

懂了没？

取非绝对是费力活啊！

有点明白了。是自己做了进一步的推理，认为如果质量不过关那就必须要CHEAP才可能让EXPORT上升!

你说得很有道理，B它是一个必要条件，就是说美国能满足质量要求，而且还CHEAPER了，所以增加了EXPORT上升的可能性，但我感觉B不是唯一一个必要条件。

预测是双刃剑啊~我之前预判的假设是“日本和西欧人一定会来买美国人的东西”
