大全-10-13-->携隐修改标题（新东方绿皮书 逻辑99）

99 Exports of United States wood pulp will rise considerably during this year. The reasong for this 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?

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 costs were not a factor.

答案给的是B

我认为B选项和C选项的目的是一样的：即考虑到价格下降以后，日本和西欧的厂商对美国产品的进口量会增加。但实际上，B提到的是质量问题，而C涵盖的方面更广：排除价格因素的考虑，美国产品更受欢迎，这里自然包括了B中提到的质量符合要求这一条。

当然，可以说if costs were not a factor有问题。但应该是价格的下降更促进了这种偏好吧。

大家讨论一下，给个意见吧

假设是要文章给定的信息来推理的，

逻辑是推不出prefer to 这样的答案的，因为prefer to 是一个主观色彩的词组.

C. Paper manufacturers in Japan and Western Europe would prefer to use wood pulp produced in the United States if costs were not a factor.

可以说价格成为一个因素后,日本人和欧洲人更喜欢用美国的WOOD PULP了，也可以说价格成为一个因素后，日本人和欧洲人就不喜欢用美国的WOOD PULP了，不管这价格是高了是低了。

C的问题不是在COST WERE NOT A FACTOR,而是在PREFER TO 上。

if the costs is a factor, they will never choose American pulp because there is even cheaper pulp from Thailand.

文中由华盛顿贬值，推出日本和西欧买美国的纸浆会比买其它地方的纸浆要便宜，所以纸浆出口要增加。

如果价格不是一个因素的话，日本和西欧会买美国纸浆。意即价格相同的话，美国的纸浆受欢迎。这个假设文中没有。文中只说美国的纸浆比别的地方便宜了，所以他们才买的。
