13. 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.

这道题选B，可是想不通为什么C不行。而且B中的quality会不会有点out of scope了呢? 感觉B，C两个取非对原文都有削弱作用哦，请指点~

关键对原文逻辑的把握。原文的逻辑是：美国货便宜，所以日本和西欧会购买。B说美国货质量必须满足要求。将它取非后，结论就推不出了（不合要求，再便宜也没用）。C的核心是J，WE更爱美国货。J，WE买美国货是因为便宜，更爱不爱无关。C很容易混，但方向偏了。其实原文只要能搭起便宜就会买的桥就可以。

可是如果把C取非：如果价钱不是个问题，J和WE也不会考虑买。这不也是削弱吗？这同样搭起了价钱和买之间的桥啊？

lawyer GG说的，想不同啊，请继续指点！

取非的的方法，当选项的取非问题较复杂时，还是慎用，会TRICK自己。见到昨天帖子对取非的讨论了吗。

1。C的谓语是WOULD PREFER TO，更喜欢的意思，是主观问题，“取非”后变成不喜欢，还是主观问题。而原文的推理是建立在利益基础上，是客观问题

2。取非是直言判断才能取非（见昨天讨论），假言判断没说到取非问题。

3。C的意思为：如果不考虑价格因素（请细考虑这句话的隐含含义），J和WE更愿意买美国货。而原文却说价格便宜才买，价格是个决定因素。这个考虑角度不一样，价格是个决定因素需要不考虑价格因素这样的假设吗。

谢谢lawyer gg的解释，好详细，让我对assumption有了进一步的理解。

我想问一下有关取非的讨论在那个链接？我想看看可找不着哦～

  pls~~~need nn's aid~~why D is wrong?? i think D rules out the possibility of other factors such as demand for paper products made in japan and W Europe...so the falling value of the dollar will be the assumption to draw the conclusion.
