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.

Its important to note that, answering a verbal question is more like negating all the wrong answers.

stimulus: bamboo strong as steel and sturdier than concrete, tropic areas they are < expensive. So, where land values are high,we cannot use bamboo.
But using bamboo should be economical. But why not?
a. earthquake - irrelevant. question is clearly talking about economical and bamboos
b. Bamboo unsuitable as a building material for multistory buildings. - could make sense. Higher land values, more multistory buildings. No bamboo. explains.
c. again irrelevant - [you cannot connect termites with high land values]
d. so what they use for scaffolding. it still doesnt talk about constructing buildings.
e. again irrelevant - so if land values are increasing and bamboo growing. doesnt talk about bamboo being used for constructing buildings

Please also note in such type of questions - the above is explained by which of the following types, usually NEW INFORMATION is better suited.

Even in B we are having a assumption that in case if the land value is high people would use Apartments . I think this is out of scope.

B is the strongest via POE.
But it would have been better if the wording was changed:
"Bamboo is unsuitable as a building material for multistory buildings"

I picked up C over B, because thought, ther is an additional cost, so high land values + additional expense => could be a deterrrent for using bamboo on high value lands

Now, i see that "some" is not a favorable "adj" to be chosen as a correct option

Bamboo is stronger than steel and strudier than concrete. In tropical areas, bamboo is cheap and readily available. Hence this is a good option to build expect when land values are high.

When land values are high, it is always a viable option to build multi-storeyed buildings to provide more living area.

B. Bamboo is unsuitable as a building material for multistory buildings - Provides the link to connect premise and conclusion. - Correct

Somehow,I am not at all with the solution that OG gave:

Following is an extract from OG-13 Solution Q94:
Multistory buildings are particularly desirable in areas where land values are high, but
bamboo may not be suitable for such buildings.

Now where in the stimulus there is mention of the above reasoning ?

It is just that we are assuming and that isn't allowed in GMAT CR?

Hi Target,

It is given in the answer 'B', the whole point of this sort of question is evaluating which of the options provides EXTRA information that helps explain the paradox in the passage.

So which of the answers A-E gives additional info that would explain why Bamboo is not used. Answer B does that so is correct.

Rgds,

Hi,

The highlighted statement is actually not true and most people have misconceptions around this.

GMAT CR section is not about formal logic where you have to take the literal meaning of each word and convert that into a logical representation using sets or some other notations and then apply classical logical rules to arrive at the answer.

Rather, GMAT CR section is a test of your everyday logic and thus, it uses some of the most intuitive understandings such as

1. People prefer more profit over less profit
2. Dollar sales should increase with the increase in the number of customers
3. A person who is more willing to use meditation technique is expected to use such techniques over a longer term than a person who is less willing.

Don't you think these statements seem very common sense?

However, as you can see that these statement can also be false in some specific scenarios; however, generally, they make a lot of sense. Actually such understanding is needed to tackle a lot of CR questions.

I did not create these three statements out of thin air. The understanding of such statements are needed to tackle below three respective OG questions:

Question 1

One name-brand cereal manufacturer is about to reduce wholesale prices for its cereals by 20% because consumers have been switching from its cereals to cheaper store brands. The success of this strategy relies on the assumption that supermarkets will pass on all of the savings by lowering the prices they charge consumers for the manufacturers' cereals. Although supermarkets usually pass on such savings, in this case it is likely that supermarkets will not do so because ............................................................

a) Several other name-brand cereal manufacturers are about to reduce the wholesale prices of their cereals
b) the average price per box of name-band cereals has significantly increases over the past 10 years.
c) total annual sales of cereal - including both name-brand and store-brand cereals -have increased over the past 10 years.
d) supermarkets currently make far more profit on sales of store-brand cereals than on sales of name-brand cereals
e) the current prices of manufacturers' cereals are comparable to the prices of name-brand cereals produced by other cereal manufacturers.

Correct Option: D

Question 2

Theatergoer: In January of last year, the Megaplex chain of movie theaters started popping its popcorn in canola oil, instead of the less healthful coconut oi that it had been using until then. Now Megaplex is planning to switch back, saying that the change has hurt popcorn sales. That claim is false, however, since according to Megaplex's own sales figures, Megaplex sold five percent more popcorn last year than in the previous year.
Which of the following, if true, most seriously weakens the theaterg0er‘s argument?
A. When it switched from using coconut oil to using canola oil, Megaplex made sure that the chain received a great deal of publicity stressing the health benefits of the change.
B. Megaplex makes more money on food and beverages sold at its theaters than it does on sales of movie tickets.
C. In a survey to determine pubic response to the change to canola oil, very few of Megapiex's customers said that the change had affected their popcorn-buying habits.
D. Total sales of all food and beverage items at Megaplex's movie theaters increased by less than five percent last year.
E. Total attendance at Megaplex's movie theaters was more than 20 percent higher last year than the year before.

Correct Option: E

Question 3

A study of high blood pressure treatments found that certain meditation techniques and the most commonly prescribed drugs are equally effective if the selected treatment is followed as directed over the long term. Half the patients given drugs soon stop taking them regularly, whereas eighty percent of the study's participants who were taught meditation techniques were still regularly using them five years later. Therefore, the meditation treatment is the one likely to produce the best results.
Which of the following, if true, most seriously weakens the argument?
A. People who have high blood pressure are usually advised by their physicians to make changes in diet that have been found in many cases to reduce the severity of the condition.
B. The participants in the study were selected in part on the basis of their willingness to use meditation techniques.
C. Meditation techniques can reduce the blood pressure of people who do not suffer from high blood pressure.
D. Some of the participants in the study whose high blood pressure was controlled through meditation techniques were physicians.
E. Many people with dangerously high blood pressure are unaware of their condition.

Correct Option: B

Look at the correct answers of the above questions and look at the three common sense statements I made and observe that without those common sense statements, the correct answer choices will not be correct.

Similar is the case with the current questions: We need to have this understanding that places where land values are high, multistory buildings will be preferred since on the same land, we can have more office or house space.

Hope this helps

Let me know if any further clarification is needed.

Thanks,
Chiranjeev

Sorry to say still nobody has answered my query.

In tropical areas, therefore, building with bamboo makes better economic sense than building with steel or concrete, except where land values are high.

Paradox is even if BAMBOO makes economic sense then why IT is not used in where land values are high

(B) Bamboo is unsuitable as a building material for multistory buildings.

How can we assume here that places where LAND VALUES ARE HIGH we will find MULTISTORY BUILDINGS.

Places where LAND VALUES are high can be the places where there are BUNGALOWS or may be the land values could be high because "Very important People" are living there.

How could we relate HIGH LAND VALUES with MULTISTORY.

I contradict the reasoning of common sense as given by other members in this post.

Rgds,
TGC

I sort of agree with your reasoning that high land values does always equate to multi-storey, for example not every building in Monte Carlo (one of THE most expensive places per sqft in the world) is a multi-storey building. So yes, although it may seem like a logical conclusion, it is not a given that high land values equates to only multi-storey buildings. BUT, looking at all the other options you will have to select a possible answer.

I suppose GMAT is also testing your skill of eliminating the wrong choices and in this case after the process of elimination you are left with B. It may not be the best possible answer but of the 5 choices it is.

Hope that makes sense.

Please elaborate why Option B is correct.
Instead option A is indicating that Physician suggestion-->is to do Meditation . so this should be the right answer dont you think?

B is correct because it says that the people in the trial were already keen on meditation - hence they would be more likely than the population at large to continue with that treatment.

So it makes the statistics used for the trial irrelevant for the population as a whole.

As for A, it seems totally out of scope for me. The question is meditation vs drugs. Diet has nothing to do with it.

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.
D)Doesn't answer out question in any way. Out.

B wins.
