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?
Converting the branches into wood chips at the logging site would require transporting a fully assembled wood-chipping machine to and from the site.
It would be more economical to debranch the trees at the factory where the fiberboard is manufactured.
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.
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.
In the wood-processing industry, branches are used only for the production of wood chips for fiberboard.
UL要做两个木制产品，把树枝做成wood chips（WC）再做成纤维板；不管是在伐木地做，还是在工厂做，成本一样；
但是，WC的数目少于原材料树枝的一半（也就是说，做WC的过程存在损耗）
求问∴
conclusion题
A、在伐木地做，需要来回搬机器，无关，没提机器
B、砍树枝在工厂做更实惠，无关，反原文（这个选项考虑了钱，有所暗示）
C、加工过程很简单，所以在伐木地做很实惠，无关，反原文（这个选项考虑了钱，有所暗示）
E、在木加工业，树枝只用来做WC，无关

D、
重点不是说从logging site运到factory，而是落在后半句，也就是说运输成本的问题。
因为题干说到wood chips occupy less than half the volume of the branches from which they are made，
也就是说branch加工成chip是要耗损的，耗损的量大概是一半多。
所以，运输成本的高低就取决于它是在产地加工，还是在工厂加工，如果在产地加工完再运到工厂，因为已经排除掉了耗损，所以cargo的数量就会少一些，那成本就比较低，就会比较好（用了原文“损耗”的信息得出结论）
只有因

那么直接在伐木现场制好纤维板，运输费就会少很多
choice d, 从logging site到factory的运输费用（由货物体积决定）会更低，如果conversion在logging site完成。correct。同等体积的branches( 假设体积V) 如果在logging site转换，体积变成(1/2 V )运输到factory。
D选项，假设一：运输费用是由volume决定；假设二：木屑后，volume减少（此为段落最后一句）。
结论：如果就地变成木屑，运输费用会低一些。
段落最后一句补充了D选项的第二个假设，因此能够support D选项的结论。
2 wood chips 占用的地方是branches的一半
d提到了货物的volume，根据2可以得到，在砍伐地将树枝转化成wood chips可以减少volume，因此可以减少运输成本，正确！
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.
