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?

Buildings constructed of bamboo are less likely to suffer earthquake damage than are steel and concrete buildings.

Bamboo is unsuitable as a building material for multistory buildings.

In order to protect it from being damaged by termites and beetles, bamboo must be soaked, at some expense, in a preservative.

In some tropical areas, bamboo is used to make the scaffolding that is used during large construction projects.

Bamboo growing in an area where land values are increasing is often cleared to make way for construction.

考题讲解

毕出

情景：作为一种建材，竹子的坚固程度比钢铁和水泥有过之而无不及。除此之外，在热带地区竹子比钢铁和水泥便宜很多且容易得到。因此，在热带地区，用竹子建成的房子比用钢铁或水泥建成的房子经济效益更高，除了地价很高的地区外。

推理：请注意，本题的问题是让我解释为什么“除了地价很高的地区外”。因此实际上就是让我们找出地价很高的地区和其它地区的区别。因此，本题为类比推理，类比对象是“一般地区”和“地价很高的地区”。

选题方式：

选项分析：

A选项：由竹子建成的房子比用混凝土和钢筋建造的房子更不容易受到地震的伤害。本选项没有提及案例名称。

B选项：Correct. 竹子不适合建造高层建筑。相对于一般的地区来说，地价高的地区的建筑一般都是高层建筑。因此本选项提及了两个案例。属于CQ1：相似性问题。

C选项：为了防止白蚁和甲壳虫破坏竹子，竹子一定要在防腐剂中浸泡。本选项没有提及案例名称。

D选项：在某些热带地区，竹子被用来制作用于建筑项目的脚手架。本选项没有提及案例名称。

E选项：生长在地价高的竹子经常会被为了建房子而清除掉。本选项没有提及案例名称。
