13 Exports of United States wood pulp will rise conderably 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?

答案给的B The quanlity of the wood pulp produced in the United States would be adequate for the purposes of Japanese and Western European paper manufacturers

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

statement的结论就是Exports of United States wood pulp will rise conderably during this year。 原因简单说就是cheaper.

price 受价值和供求影响，只有当其中一个保持小变动或不变，另一个因素的大变动才会引起price的变动啊  所以D才是应该增加的assumption啊  跟B有什么关系？
