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?
Factory output of paper products in Japan and Western Europe will increase sharply during this year.
The quality of the wood pulp produced in the United States would be adequate for the purposes of Japanese and Western European paper manufacturers.
Paper manufacturers in Japan and Western Europe would prefer to use wood pulp produced in the United States if cost were not a factor.
Demand for paper products made in Japan and Western Europe will not increase sharply during this year.
Production of wood pulp by United States companies will not increase sharply during this year.
b我选对了，但是不明白c为什么错了，哪位大神可以帮忙解释一下！
是因为说成本不是因素，否定前提了吗
如果他们不在乎成本，那么不管美国的木材是贵还是便宜他们都会买，而不是因为降价所以加大采购量。这个选项可以看成削弱。
不在乎成本--木材降价也不会加大采购量--削弱结论，而不是推出结论：他们会加大采购量必需的一个因素。
prefer是对比出来的，除非原文给出美国产品与其他国家产品在价格无明显差距时，日本工厂进口这些国家产品的比例。
