7.    (24401-!-item-!-188;#058&001291)






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

为什么我觉得这题应该是paradox，答案也有新信息，但是题干的类型又是must be true的感觉？

首先分析一下这段文字，依次提供了以下几个主要信息：
1、两个产品，一是树桩做lumber,而是branches做成chips,chips再做成fiberboard;
2、把branches做成chips,可以在伐木现场做，也可以在工厂做，无论在哪里做，做的成本是一样的；
3、Chips占的空间，要比branches小一半。

以上是这段文字传达的信息，本题的难点其实也就在这里，几句废话，含了好几个信息，搞得读者不知道到底要从哪个信息来出题，每点都可以开花，因此有点绕。
其他几个选项就不分析了，看答案D，如果在伐木现场，就把branches做成chips, 再如果从伐木现场到工厂的运费，是由货物体积决定的，那么做成Chips后的运费要便宜。这个结论是可以从题干文字传达的第三个信息得出来的，其他两个信息对于答案D来说都没用。

先把问题搞清楚，这是MBT，没有搞清楚会当成paradox的
