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.

在B和C之间抉择了很久，俩个说的差不多是一个事吧？答案是B

C项中,加入了一个人为的假设,就是认为日本,欧洲不购买美国的产品就是因为美国产品的价格高,
有了这个假设所以才会选C的,其实这个假设根本不一定成立
而B项明显更加直接了当
至于LAWYER的解答,个人觉得过于学术
