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.
答案 d 红字那句话 不明白...
我理解是：wood chip 只占 那些branch总体积的不到一半
但是... 这根 factory 和 logging site 的比较 没什么关系阿....
thx 。。。。。。。

原文说，branch用来加工成wood chips，而且在砍伐现场的加工成本=在工厂的加工成本
但是又说branch加工成wood chips的时候，有多于一半的料都废掉了（比如100立方branch只能加工出30立方wood chips）
那这么看来，把branch运回工厂再加工肯定不划算了，因为运了很多废料回来，运输成本上升了。选D

我的理解是这样的：
因为刨出来的wood chips 只占了不到branches的一半，的意思就是有一多半的木料其实是废的。
所以如果把木头拖到 factory去加工的话，那没有用的一多半木料就会占用运送的空间（反正到了工厂加工完也是扔掉 何必再花钱运送过去），造成运送成本的增加。
因此，在 logging site 刨 wood chips 会比较省钱。
我认为理解这道题的关键是认识到这道题的题型
这是一道“归纳题”即运用文章信息推出正确选项
而非“解释题” （解释文章的矛盾之处）
