GMAT逻辑题一直以来是不少考生的弱项，因为逻辑题考查的不只是考生对于英文题目的阅读和理解能力。考生必须具备一定的逻辑推理思维能力才能做好此类题目。下面小编就通过一些GMAT逻辑真题的完整分析来为大家讲解这一难点题型的解题思路和技巧。
例题分享：
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.
