OG2017上的CR题

630. As a construction material, bamboo is as strong assteel and sturdier than concrete. Moreover, in tropicalareas bamboo is a much less expensive constructionmaterial than either steel or concrete and is alwaysreadily available. In tropical areas, therefore, building withbamboo makes better economic sense than building withsteel or concrete, except where land values are high.' Which of the following, if true, most helps to explainthe exception noted above?
(A) Buildings constructed of bamboo are less likelyto suffer earthquake damage than are steel andconcrete buildings.
(B) Bamboo is unsuitable as a building material formultistory buildings.
(C) In order to protect it from being damaged bytermites and beetles, bamboo must be soaked,at some expense, in a preservative.
(D) In some tropical areas, bamboo is used tomake the scaffolding that is used during largeconstruction projects,
(E) Bamboo growing in an area where land valuesare increasing is often cleared to make way forconstruction.


答案是B。OG的解释是:
B Correct.  Multistory buildings provide a greater area o f floor space for a given site area, and in that senseare more economical. A single-story building w ith the same floor space w ill occupy a much bigger site, sothe higher the land values, the more likely it is that a m ultistory building w ill be b uilt on that land. Thus,given this information, bamboo is less suitable for areas where land values are high.

解释很好理解，竹子不适合高层建筑，而高层建筑在地价高的地方更经济。但是我记得我在不少地方都看到说，题目中没出现的就当自己都不知道。但很明显这里题目中根本没提到高层建筑。遇到类似的情况，我是该让自己“知道”呢，还是“装傻”不知道呢？

谢谢！

我觉得这个问题很难有一个确切的答案。有些时候是common sense，有些时候是assumption。但每个人的knowledge base又都不一样，对于你的common sense可能对于我来说就是一个assumption。所以我觉得做题的时候，不用刻意‘装傻’，你自己觉得是common sense的事情就不用过多考虑，也没有时间让你过多考虑。如果做错了，嗨，你和别人不一样，很多时候这也是一件好事儿。
