阳阳的家上的逻辑讨论

Exports of United States wood pulp will rise considerably during this year. The reason for this rise is that the falling value of the dolalr 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 touse 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
答案是：B

B：美国木材的质量适合，价钱又低-----大量购买
C：价钱不是问题。与原题矛盾。WEAKEN
D：这两处地方对纸产品的需求没升高---不会大量进口。WEAKEN
E：木材产量没升高。怎会will rise considerably during this year呢？
