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. 正确选项是D 我有点不太明白，请高手指点作者: 米小咪 时间: 2011-7-20 15:44
哎 我自己顶自己一下吧 没人理啊 哪位高手帮忙看看作者: gmgmwll 时间: 2011-7-20 16:47
只是自己的理解 不知道对不对 题目说 把branch 变成fiberbroad 在logging的地方做和在工厂做成本是一样的 但是 chip所占的空间比branch的一半还少 问支持什么 D说 因为运输费同货物体积有关， woodchip占地小 所以在logging的地方就把branch变成woodchip了。都是讲volum的 A讲到要用machine 无关项 B相反吧 说在工厂debranch好 C说这两个步骤是工厂在logging site 做的唯一有economic advantage的两步 无关 E更无关啦 不知道这样理解对不对～～
