REP2-7
7.(24401-!-item-!-188;#058&001291)United Lumber will use trees from its forests for two products.The treetrunks 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 wouldrequire 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 theconversion of the branches into chips are the only stages in the processing of branches that it wouldbe 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.
这题说在伐木场和工厂的cost一样。但是把树枝变成木屑体积变轻。运费变少。那么把树枝运到工厂和把木屑运到工厂的cost显然不一样啊。那不如在伐木场把树枝变成木屑了。那不成削弱了么。求解释。

background:United Lumber will use trees from its forests for two products.treetrunks:lumber.branches: wood chips-----fiberboard.
conclusion:the cost  of conversion is same:logging site or united's factor
evidence:wood chips occupy less than half the volume of the branches from which they are made
must be true.
do this type of question.you should make the clue.
D is best.not weaken.i think you should pay attention to these words:cost of conservation(not the cost of transportation),half the volume. the clue like this:the total cost of T=volume*per cost of T.cause the volume decrease,the total cost of T decrease.choice(D) is completely true

不好意思。还是有些不明白。结论不是在伐木场还是在工厂cost是一样的么。

那D是怎么支持结论的。没关系呀。不明白

我也范了和你一样的错误，其实这道题是归纳题。并不是加强题。是问的文章支持哪个选项。
