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?

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 ways of construction.
OA:B
解释:land value high = multistory building
我认为这是一个题干以的assumption,疑惑为什么可以用”常识’来加上去?
因为如果可以乱加assumption的话:我可以说选项A:land value high = high possiblility of earthquake;选择A
