10.   Last year the worldwide paper industry used over twice as much fresh pulp (pulp made directly from raw plant fibers) as recycled pulp (pulp made from wastepaper). A paper-industry analyst has projected that by 2010 the industry will use at least as much recycled pulp annually as it does fresh pulp, while using a greater quantity of fresh pulp than it did last year.

If the information above is correct and the analyst’s projections prove to be accurate, which of the following projections must also be accurate?

(A) In 2010 the paper industry will use at least twice as much recycled pulp as it did last years.

(B) In 2010 the paper industry will use at least twice as much total pulp as it did last year.

(C) In 2010 the paper industry will produce more paper from a given amount of pulp than it did last year.

(D) As compared with last year, in 2010 the paper industry will make more paper that contains only recycled pulp.（A）

(E) As compared with last year, in 2010 the paper industry will make less paper that contains only fresh pulp.

兄弟我彻底晕！到底谁是谁的2倍呀？

则么感觉比数学还难？多帮忙，谢谢

I think this is a difficult question for American, so the answer is A.

Last year: fresh pulp= 2*recycled pulp

2010: recycled pulp>=fresh pulp

So we can conclude: in 2010 the paper industry will use recycled pulp>=2*recycled pulp used in last year.

哈哈，leeon这句回答的妙。

我觉得一旦涉及到两个事物相互的比率换算来换算去，对老美来说就是难题，基本上就是选A。不过这道题目的D我觉得也满混淆的，若不是only绝对词排除，我差点觉得D也是对的。看来对原文的理解必须细致又细致啊。

虽然是去年的帖子，这里我也补充一句。

1。这题是对平均水平的老美又难度的题，不是所有，所以不应该用American

2。D之所以不对是因为原文没有关于how many paper are made from pulp的信息。原文只说了用了多少pulp。所以，D E都不肯能对。

我怎么觉得A说的并不全对呢？似乎应该是大于，不存在等于的情况吧

Last year: fresh pulp1= 2*recycled pulp1

2010: recycled pulp2>=fresh pulp2     且   fresh pulp2>fresh pulp1

So we can conclude: in 2010 the paper industry will use recycled pulp>2*recycled pulp used in last year

就因为这个等于没敢选A
