标题: 新东方蓝书逻辑第38页99题求解
Exports of United States wood pulp will rise consid-
erably 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 West-
ern 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.

答案选B，但我觉得C更合适

B只说到了quality adequate，这不是Japanese and Western European buy American wood pulp的必要条件。

C排除了一切其他情况，只要cost合适就买，而原文中正好提及了美国cheaper than from any other source. ，所以我觉得选C很恰当。

盼高人解答！

B是假设 C是加强

楼上是怎么区分b和c是加强和假设的呢

C是削弱，怎么是加强啊，更愿意使用美国木浆如果价格不是问题，直接打击了原文推论：the reason for 美元跌了木浆便宜了——》鬼子和欧人来买了就是冲价格便宜来的

B是说The quality of the wood pulp produced in the United States would be adequate for the purposes，相当于前提了，LZ上XDF的？结束了没有，如果没有希望LZ能去问下逻辑老师，这里的假定题为何出现了新元素The quality of the wood pulp，等待LZ回来解答

B杜绝他因。

如果质量达不到日本和欧洲生产商的要求，即使价格便宜，也不能保证销售量会增加。所以这是一个假设。

如cxfeng19所说，C 是加强。如果问题变为which of the following supports the conlcusion? 那么C无疑是最佳答案。

不好意思LZ，我结论看错了，结论是第一句话，C是加强，但是C取非的话是无法削弱原文的

对b选项和c选项依然有点疑惑，能不能有一个比较详细的解释阿
