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.

答案是D

题干最后一句 However, wood chips occupy less than half the volume of the branches from which they are made.
我不大明白，究竟跟D项是怎样的逻辑联系？

木头片占体积小 只有不到树干一半的体积

所以 按体积计算运费的话 就便宜  也就是D选项所说的

若是按重量计算 就一样 若是有F这么写 那也可以选
