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.

想问一下 D为什么对感觉所有的都不对题目是导出题 Transpotation costs 文中根本没提不能选啊

读完题目，没看选项之前，我就想着，应该在logging site来debranch，这样，原本工厂有限的库房可以存放更多的材料。没想到题目出得是transportation，一样思路吧。同样一个truchload，原树枝只能运1/2的量，而wood chip可以运1的量。

现在想明白了答案就是说运输费是由装载货物的容积决定的，那么在logging site debranched 肯定比在factory 费用低
因为题目中说了wood chips occupy less than half the volume of the branches from which they are made，在logging site debranch 成 wood chips 后再运回去其体积小花的钱就少如果先运回去其体积大则花费大。
