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 exception noted above?
看了好多遍,看OG的解释还是不理解,为什么竹子不适合建造多层楼房呢?感觉很常见亚热带城市的几层竹子屋啊~
我自己选择的是E,我觉得土地价值高的地方不用来种植竹子是合理的,那么竹子的成本优势就显示不出来了,因为运费要很高。(所以城市建造就用的钢筋混凝土……)

therefore, building with bamboo makes better economic sense than building with

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.
