United Lumber will use trees from its forests for two products

题目

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?

选项

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.

解析

联合木材公司将用其森林中的树木生产两种产品。树干将用于木材，树枝将被转化为木屑以制造纤维板。这种转化的成本无论在伐木场（树木在此处去枝）进行还是在联合木材公司的工厂进行都是一样的。然而，木屑所占体积不到其制成的树枝体积的一半。核心论点及正确答案方向：核心论点在于转化成本相同，但木屑体积比树枝小这一关键信息。正确答案应该与体积变化所带来的相关影响有关，可能涉及运输成本等因体积变化而产生经济影响的方面。 A选项：在伐木场将树枝转化为木屑需要将一台完整组装的木屑制造机运到伐木场再运回来。该选项没有涉及到因木屑和树枝体积不同而产生的任何影响，与核心论点无关，不符合要求。 B选项内容：在制造纤维板的工厂对树木进行去枝会更经济。分析：文中重点讨论的是树枝转化为木屑的地点对经济的影响，而不是去枝地点，话题不一致，不符合要求。 C选项内容：对树枝进行去枝和转化为木屑是在伐木场进行对联合木材公司有经济优势的唯一阶段。分析：没有利用到木屑体积小于树枝这一关键信息，无法从所给信息中得出这是唯一有经济优势的阶段，不符合要求。 D选项内容：如果在伐木场而不是在工厂将树枝转化为木屑，按货物体积计算的从伐木场到工厂的运输成本会更低。分析：因为木屑体积不到树枝体积的一半，所以在伐木场转化为木屑后运输，运输成本（按体积算）会降低，该选项利用了题目中的关键信息，符合正确答案方向，是符合要求的。 E选项内容：在木材加工行业，树枝仅用于生产纤维板的木屑。分析：与题目讨论的重点即转化地点及体积变化带来的影响无关，不符合要求。答案：D
