PREP2-7居然没看懂，请帮忙

7.    (24401-!-item-!-188;#058&001291)

United Lumber will use trees from its forests for two products.  The tree trunks will be used for lumber and the branches converted into wood chips to make fiberboard.  The cost of this conversion would be the same whether done at the logging site, where the trees are debranched, or at United's factory.  However, wood chips occupy less than half the volume of the branches from which they are made.

The information given, if accurate, most strongly supports which of the following?

(A) Converting the branches into wood chips at the logging site would require transporting a fully assembled wood-chipping machine to and from the site.

(B) It would be more economical to debranch the trees at the factory where the fiberboard is manufactured.

(C) The debranching of trees and the conversion of the branches into chips are the only stages in the processing of branches that it would be in United's economic advantage to perform at the logging site.

(D) Transportation costs from the logging site to the factory that are determined by volume of cargo would be lower if the conversion into chips is done at the logging site rather than at the factory.

(E) In the wood-processing industry, branches are used only for the production of wood chips for fiberboard.

顶一下，快考试了，急

700以上的题库这种难度的很多，我就简单说大概意思: 美国的采伐业主要将树木的两种材料进行加工，树干和树枝，在采伐现场和在工厂对这两种材料的加工，成本没有差异，然而木屑只占树枝的体积的一半。

答案是引入运输的他因，体积大运输成本就高。

其实主要在考阅读，抓几个关键字，体积；加工成本；运输

debranch这词我是猜的，可能是砍剪树枝

wood chips occupy占（体积） less than half the volume of the branches from which they are made.

木屑占树枝体积的一半不到。和运输前后无关

D是说在现场弄成木屑最好，那为什么不全部弄成木屑，好让体积小一些

但是文中最后一句话为什么是LESS THAN呢？？不懂

(C) The debranching of trees and the conversion of the branches into chips are the only stages in the processing of branches that it would be in United's economic advantage to perform at the logging site

川妹妹，你别急，你说的对：弄成木屑，好让体积小一些，运输成本低，所以D

这题不选C

the only stages 是不对的，C的整个选项都没说到点儿上，她说剪伐树枝转化木屑很重要，没用。

我刚才写错了，本来想写D的结果写成C了嘿嘿

如果都弄成木屑的话，为什么文中说木屑反而少呢

哎，我完全糊涂了

懂了，我把However看成与上面的那句话关联了，想成了是这个公司采取行动后的一个结果

原来是要把它看成一个常识，作为前提来推结论，真是啊

谢谢上面的大大好人京哥哥,送花送花
