94. As a construction material, bamboo is as strong as steel and sturdier than concrete. Moreover, in tropical areas bamboo is a much less expensive construction material than either steel or concrete and is always readily available. In tropical areas, therefore, building with bamboo makes better economic sense than building with steel or concrete, except where land values are high.
Which of the following, if true, most helps to explain the exception noted above?
(A) Buildings constructed of bamboo are less likely to suffer earthquake damage than are steel and concrete buildings. (B) Bamboo is unsuitable as a building material for multistory buildings. (C) In order to protect it from being damaged by termites and beetles, bamboo must be soaked, at some expense, in a preservative.
(D) In some tropical areas, bamboo is used to make the scaffolding that is used during large construction projects.
(E) Bamboo growing in an area where land values are increasing is often cleared to make way for construction.
Answer: B
premise1：bamboo和steel在作为装修材料时是一样结实，而且bamboo比concrete要更结实
premise2：bamboo在热带岛屿地区相比起其他装修材料（steel或是concrete）要更便宜，并且更容易获得
conclusion：在建造时，用bamboo比steel或是concrete更经济一些，但是除了在高价值的地区
OG解释：“Situation： Bamboo is as strong as steel and sturdier than concrete when used as a construction material. In tropical areas, bamboo is much less expensive and is always readily available.
Reasoning： What explains the exception specified in the conclusion? The argument’s conclusion is that in tropical areas bamboo is a more economical building material than steel or concrete, except where land values are high. The information in the passage makes clear why bamboo is a more economical building material in tropical areas than are concrete or steel. So the question is: Why must an exception be made for areas where land values are high? Multistory buildings are particularly desirable in areas where land values are high, but bamboo may not be suitable for such buildings.” OG说一块儿土地价值高，那么这块土地上就有多层的建筑物
注意：我在做题的时候还想到了这个因素，我在看选项B的时候，就在想，你妹的GMAC是不是又在阴我，想让我犯常识误导错误，即土地价值高和多层建筑物根本就没有本质联系，有些地方土地价值高，也没有多层建筑物啊。
结果...，中枪~~
（PS：看了babybearmm的心经给我们推荐的FOV即Foundations of Gmat Verbal，里面告诉我们通常推理的12个错误，首当其冲就是常识或称为共识代入错误！！！书中告诉我们 第一个错误就是Assume shared belief，即我们做题时经常把一些大家都接受的东西作为假设，书中说道：[attach]122542[/attach]，翻译过来意思就是不要认为任何事情是理所当然的，比如这道题里，高价值地区，一定有高楼层的房屋吗？）
