请教一下以下这道逻辑题，Exports of United States wood pulpwill rise considerably during this year. The reason for the rise is that thefalling value of the dollar will make it cheaper for paper manufacturers inJapan and Western Europe to buy American wood pulp than to get it from anyother source.

Whichof the following is an assumption made in drawing the conclusion above?
(A) Factory output of paper products inJapan and Western Europe will increase sharply during this year.
(B) The quality of the wood pulp producedin the United States would be adequate for the purposes of Japanese and WesternEuropean paper manufacturers.
(C) Paper manufacturers in Japan andWestern Europe would prefer to use wood pulp produced in the United States ifcost were not a factor.
(D) Demand for paper products made inJapan and Western Europe will not increase sharply during this year.（B）
(E) Production of wood pulp by UnitedStates companies will not increase sharply during this year.
答案选择的是B，但是A为什么不正确呢？题干的结论似乎是Exports of United States wood pulp will rise considerably during this year.如果A没有发生，即Factory output of paper products in Japan and Western Europe不会大幅度增加，也就是说工厂不需要这么多浆，那美国的出口怎么会大幅度增加呢即使便宜了？
多谢解答。

我个人认为，这题目是要表明因为变的便宜了，所以出口的多了，前提是纸张满足质量问题，否则即使便宜也不会增大需求的。至于A项，我是这样理解的，即使工厂不会增加产量，也会因为美国的纸张便宜而增加从美国进口的数量，这可以通过减少从其他地方进口来实现。比如，以前从美国进口30，其他地方进口70，现在因为纸张便宜，从美国进口70，其他国家进口30，总产量没变，但是从美国的进口增加了。
