I think this question is terrible.

Answer (B) is right because of the external fact that high land value implies multistory buildings--this is a fact they expect you to be able to reason. I don't care for this, but I think it'd be more acceptable if E wasn't also defensible using external knowledge.

e.g., E, which I picked:

It reads:
Bamboo growing in an area where land values are increasing is often cleared to make wayfor
construction.

Since the stimulus reads: "in tropical areas bamboo... is always readily available."

And answer E explains that in areas where land values are increasing (which are the areas outlined by the exception in the stimulus), bamboo is NOT readily available, I think it's reasonable to conclude that bamboo is no longer an economical option because the availability--a premise of its economical quality in the first place, is no longer true.

To me, it's MORE reasonable than B, which involves introducing a totally new factoid, while E requires cobbling together pieces of the stimulus and the answer choice. That's what I liked about the LSAT: LSAC could throw out questions that had arguable ambiguity like this one. On the actual GMAT, I wouldn't even know I got this wrong.

(A) Buildings constructed of bamboo are less likely to suffer earthquake damage than are steel and concrete buildings.

Accentuates the paradox. This does not explain why bamboo does not make better economic sense in areas where land values are high.

(B) Bamboo is unsuitable as a building material for multistory buildings.
Initial Thought OFS. But after reading all other choices, this looked better.

Retrospection:

High land value leads to construction of multi storied buildings.( Is not there some element of assumption in this? I am not comfortable having to assume in these kind of questions and particularly in answer choices)

(C) In order to protect it from being damaged by termites and beetles, bamboo must be soaked, at some expense, in a preservative.

Some expense does not fully justify not making better sense. Moreover, this has got nothing to do with high land values which is the key for the question.

(D) In some tropical areas, bamboo is used to make the scaffolding that is used during large construction projects.

Does not explain the paradox.

(E) Bamboo growing in an area where land values are increasing is often cleared to make way for construction.

It initially made some sense to me since Bamboo may not be available where land values are high since it is cleared. But the word increasing put me off. Moreover, The question talks about economic sense but not about availability.

I disagree on the correct answer choice.

Here we are asked to fill in an assumption which connect high land values and not using bamboo.

Answer choice B satisfies the latter and provides us enough reason to not use Bamboo; however, it fails to connect the reason which states "Bamboo should not be used when land values are high".

That is my concern here. If we ignore the degree of assumption, we can connect any choice in the world in these connections. However, the assumption here is not too extreme. But I still prefer not making an assumption in evaluating a choice in the resolve the discrepancy problems.

This is OG. I don't know how to take it. But which other choice is better in your opinion?

I went with Option C. Its the only option which refers to an increase in cost. I see all the other options as irrelevant. Option B sounds way out of scope. If the conclusion of the argument was "We should not build build buildings with bamboo" or something similar I would go with B.

I feel this question is way ambiguous.

I don't know whether my reply still counts or not. But why has everyone rejected Option E. The question clearly states:

"Moreover, in tropical areas bamboo is a much less expensive construction material than either steel or concrete and is always readily available."

"Is readily available".So if Bamboo growing in an area where land values are increasing is often cleared to make way for construction means Bamboo is not available readily. Hence it is not viable to use.

This makes more sense to me rather than simply assuming high land value = multi storey building.

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.

I haven't seen such a question type where the GMAT boldly asks you to think why for a particular argument.
A) Strengthens the case.
B) Bingo ! this has high probability of being the answer.
C)hmm..doesn't answer our case. Irrelevant.
D)Doesn't answer out question in any way. Out.
E)Incomplete Answer choice.

B wins.

The problem with your logic is that you are going against the premise, a thing that is not allowed in GMAT. When the premise says that "bamboo is always readily available", an option statement indicating something against it is wrong for the reason that it contradicts the passage.

In addition, this is an official question and the official answer is B, so if you think E is correct, you think GMAC is wrong - not a fruitful way to approach GMAT.

Thanks,
Chiranjeev

You don't build with bamboo, an economically sound material, in areas with high value because it would devalue the land price. You want to increase value by using high quality, expensive materials.

my pick is E.

bamboo growing area is decreasing due to high land value, thus the total quantity of bamboo supplied is diminishing, causing the price to roar as well as the supply amount scarce, not suitable for building projects.

We need an assumption, which weakens the position of using baboo as a constructiong material. As all stated points about bamboo in the argument were positive.
Consider you have a piece of land on the seashore (expensive $/qm), which can be used to build a hotel on it. But bamboo is not a suitable construction material for multistory buildings. So if you use Bamboo you can build a building with 20 rooms instead of 120 rooms when using steel etc. --> It's a negative point for bamboo. Hence (B)
