United Lumber will use trees from its forest 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 logging site, where the trees are debranched, or at the United’s factory. However, wood chips occupy less than half volume of the branches from which they are made.
The information given, if accurate, most strongly supports which of the following?
正确选项 D.Transportation costs from the logging site to the factory that are determined by volume of the cargo would be lower if the conversion into chips is done at the logging site rather than at the factory
RON的课程里说 conclusion类的题目凡是不在the scope of the argument的都不对。D选项谈及的transportation cost算是在原文的scope内的原因是否是由原文The cost of this conversion would be the same whether done at logging site, where the trees are debranched, or at the United’s factory.这句话推理得出的？
谢谢！

并不是这句，D选项对应的应该是稳重“wood chips occupy less than half the volume of the branches from which they are made.”树枝的体积比木屑大，而运费是体积大小决定的，所以木屑的费用相对较少
