GMAT Prep SC - although impoved efficiency

by khojason » Fri Aug 27, 2010 11:01 pm
Although improved efficiency in converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices, thereby boosting consumption.

A. in converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices, thereby boosting
B. in converting harvested trees into wood products may reduce harvest rates, demand will be stimulated because of increasing supply and lowering prices, which boost
C. of converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices, which boosts
D. of harvested trees being converted into wood products may reduce harvest rates, it will stimulate demand, because it will increase supply and lower prices, thereby boosting
E. when harvested trees are converted into wood products may reduce harvest rates, demand will be stimulated because of increasing supply and lowering prices, which boost

[spoiler]Ans: B[/spoiler]




Can anyone explain how to get the correct answer of this question?

In A, the referent of it is not clear. Is it referring to harvest rates or improved efficiency?

Moreover,going by the meaning conveyed by A, whatever it is supposed to refer to (harvest rates or improved efficiency) is also boosting consumption. This is different from the intended meaning of the statement that increasing supply and lowering prices boost consumption. (A case of altered intent.)

In B, which boost... is correctly modifying increasing supply and lowering prices.

B is therefore right.

I disagree with you.

"It" is not ambigous.. It clearly refers to " improved effciency"..
"it" -singular pronoun can't refer to plural "harvest rates"

A clearly says that -
"it<efficiency> will stimulate demand by increasing supply and lowering prices, thereby (by that means) boosting consumption.

thereby is perfect here.

It says efficiency by that means (increasing supply and lowering prices) boosting consumption.



B changes the meaning..

A is the best option.


what is the source of this question. is OA right?

between A and B

A ... thereby boosting consumption is specifically talking about increase in the consumption of wood

B .... which boost consumption ... is giving a more general meaning " which is SUPPLY DEMAND RULE of econimcs...

Now to prefer A ( specific ) OR B ( generic)........ am not sure. and yes A does have a proper antecedent for it....

What's the source? I'd have definitely gone with A over B.

The first thing I noted about B was the use of the passive voice: "demand will be stimulated" is passive, while "it will stimulate demand" is active. It's very rare for the GMAT to choose a passive construction over an active one.

While we should always be concerned with pronouns, it's both grammatically and logically clear that "it" refers to improved efficiency, so that's a non-issue for this question.

Looking at the "bare bones" of the original sentence (always a good strategy for dealing with complicated sentences containing lots of prepositional phrases):
Although improved efficiency... may reduce harvest rates, it will stimulate demand..., thereby boosting consumption.
which is a very well constructed sentence.

Hi stuart, re-opening this old thread, this question was discussed many times and its an official question. The answer given is Op B.

I agree about the passive structure, but don't u think Op A and Op B, Op A states that its "efficiency" which boost the consumption while in Op B, its "increasing supply and lowering prices" which boost consumption....seems like Op B is better in terms of meaning.

niksworth!!! please see the above sentence carefully... The original sentence is a contrast sentence as it uses Although. The subject of the sentence is the 'improved efficiency'. Although improved efficiency.... how can 'it' refer to harvest rates.

also option B uses which as the modifier that specifically modifies only the prices and hence changes the meaning of the sentence..

Hence option A is always correct in this question...
IT IS TIME TO BEAT THE GMAT

LEARNING, APPLICATION AND TIMING IS THE FACT OF GMAT AND LIFE AS WELL... KEEP PLAYING!!!

Hi Stuart,
isn't B grammatically correct?

Agreed that A is better. .

IMO...

B has many issues
(1) the entire stimulation of DEMAND BY INCREASING SUPPLY AND LOWERING PRICES will boost CONSUMPTION. But in B - WHICH modifies PRICES suggesting that ONLY PRICES will boost CONSUMPTION
(2) change of BY to BECAUSE indicates CASUAL RELATIONSHIP -- its as good as saying
"This work will be done by X" vs 'This work will be done BECAUSE OF X' - they are not the same
