Dear experts,
Could you please explain why B is correct. In order B to explain the except situation above we should make assumption which, I think ,requires far more assumption than required in any GMAT CR question. Also, it is not everyone's common sense that highly valued land is used primarily for multistorey buildings. One, for example, could argue that highly valued lands is occupied by wealthy people who constructed mansions or there's not any city-like (not sure there's such a word
) objects (skyscrapers, industrial plants etc) and thus the atmosphere is fresh, so land prices are high.
On the other hand, answer choice C says that bamboo bears some additional cost. That's why total cost of construction in lower priced lands makes better economics sense. However, if we want to construct something from bamboo in high valued land there will be higher land cost+ additional bamboo costs which makes construction less efficient from economic standpoint than that of tropical areas where land prices are lower.
What I am missing here?

Mehemmed, yes, just because land values are high does NOT necessarily mean that it will be used for multi-story buildings. But we are not looking for a 100% air-tight explanation. We are looking for something that "most helps to explain the exception noted above."
Quote:
We are told that "in tropical areas bamboo is a much less expensive construction material than either steel or concrete and is always readily available." (C) tells us that there is some additional cost involved in using bamboo. But if bamboo is MUCH less expensive, who cares if there is SOME additional cost?
It's like saying that prices at Grocery Store A are MUCH cheaper than prices at Grocery Store B (assume all other factors are equal). But Store A charges a small fee for every plastic or paper bag used to bag your groceries whereas Store B does not. Would that small fee prevent you from shopping at Store A? Of course not.
More importantly, we are looking for something that explains why bamboo makes better economic sense in tropical areas EXCEPT when land values are high. Choice (C) describes a factor that would affect price REGARDLESS of whether land values are high. Thus, (C) cannot explain the exception and must be eliminated.
This post explains why (B) is the best answer.
I hope that helps!

I see the question is generating a lot of heartache. It is actually not asking you to make any uncalled for assumption.
Consider this - when you are asked to strengthen a conclusion, if you pre-think, often you are able to come up with 2-3 different ways of strengthening, right? The correct option gives you one of those ways.
Now, this is an explain question. How can we explain the exception? I am sure there are multiple ways in which we can explain it. There must be something peculiar about construction on land of high value for which bamboo doesn't work. We need to find the option that provides us one of those ways to explain the exception. That tells us what the author had in mind while noting this exception.
(A) Buildings constructed of bamboo are less likely to suffer earthquake damage than are steel and concrete buildings.
Doesn't tell us why bamboo is unsuitable for high value land.
(B) Bamboo is unsuitable as a building material for multistory buildings.
Bamboo is unsuitable for multistorey buildings. So if someone were wishing to make a multistorey building on high value land, bamboo wouldn't be suitable for it. Certainly gives one reason to note the exception.
(C) In order to protect it from being damaged by termites and beetles, bamboo must be soaked, at some expense, in a preservative.
Irrelevant
(D) In some tropical areas, bamboo is used to make the scaffolding that is used during large construction projects.
Irrelevant
(E) Bamboo growing in an area where land values are increasing is often cleared to make way for construction.
Why is this bamboo not suitable for construction, not given.
Answer (B)
No other option tells you that bamboo is not suitable for any peculiar construction. Only (B) gives one possible reason - if you are planning to make multi-storey building on the high value land, bamboo won't work. Now, if you say how am I to know that often multi storey buildings are made on high value land, if the land is expensive, the builder is expected to try to get more value out of it. It is a fairly easy connect to make. Also, since no other option provides any feasible answer, this is the best.
TGC - You may choose to make a bungalow on the land, that's ok. The answer gives us one of the reasons why bamboo may not be suitable for high value land.
) Sadly, test-takers are probably best served by accepting the GMAT with all of its flaws, and just "playing the game" so that you can move on to more important things in life.
