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.
树利用分为2部分：树干做木材，树枝叶做木屑。这种conversion加工的过程(成本=加工费+运输费)，在砍伐地方和市区里，加工费是一样的。然而，木屑的体积是树枝叶的体积一半以下(这里暗示，运输费不同，所以在砍伐地加工好)

D选项:运输费取决于货物的体积，木屑体积<树枝体积，运输木屑费<运输树枝费。加强结论

那么

题目里however，说明作者态度，要在砍伐地进行树木加工

A选项说把机器运过去很贵，是削弱作者结论的
