what is the answer? why? thanks!

OA is A

A: Best choice
B: Changes meaning. The demand would be stimulated because the increase in efficiency caused the increase in supply and the lowering of prices. Choice B says the increase in demand was caused by increase in supply and lower prices.
C: improved efficiency of converting
D: improved efficiency of converting
E : Wordy

A. in converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices,
thereby boosting. here the *it* referent is not clear but this option seems better than any other

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. - which refers to lowering prices which i think is incorrect because *supply* as well as *prices* boosts consumption

C. Of converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices,
which boosts.( same explanation as b)

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. - too wordy

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. - usage of tenses is incorrect

I think the answer is option A but i am not sure. I have seen posts in which people opted for option B.

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.

Meaning : The improved efficiency may reduce harvest rates but it will stimulate demand by increasing supply and lowering prices . The increasing supply and lowering of prices will result into boosting consumption.

So there is a cause and effect relationship between "increasing supply and lowering of prices" -> boosting consumption.

here the sentence structure of Clause + Comma + Verb+ing modifier (or participle modifier) is apt as the modifier modifies the previous clause by answering how or what resulted. Hence the usage of the modifier -> boosting is correct.

For example.
Sunita mesmerized the crowd, singing a popular song.

Now the phrase "singing a popular song" explains how "Sunita mesmerized the crowd" so the phrase "singing a popular song" modifies the previous clause.
And secondly, the action of singing attaches to the subject of the previous clause and should make sense. So in the above example, singing make sense with the subject of the previous clause "Sunita" so both the rules are satisfied for Verv+ing modifier.

So applying the same theory, the action of "boosting" attaches to the subject of the previous clause "efficiency " so the efficiency is finally boosting the consumption and that make perfect sense.

A. in converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices,
thereby boosting.
As per above analysis, the option A) looks good.

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.

which is a relative pronoun and can refer to a noun only. Here we require a cause and effect relation where we need to modify the previous clause.

C. Of converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices,
which boosts.

which is a relative pronoun and can refer to a noun only. Here we require a cause and effect relation where we need to modify the previous clause.

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.

being -> is used when the action is continuous . In this example, the action of converting is not ongoing process as we make the above statement and hence the usage of "being" is wrong.
As per the original choice -> How the efficiency will stimulate demand , by increasing supply and lowering prices. But in this option the reason for stimulating demand is that efficient will increase supply and lower prices which is a meaning change (which is not required as meaning of option A is not wrong). As per option A) it seems to be a simultaneous actions, but in option D) demand will increase because of the some future action.

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.

When cannot be used for condition. When is used for a specific time period.
which cannot refer to the whole clause and cannot modify the whole clause.

In (A) "it" refers to improved efficiency without any ambiguity. "harvested trees" , "wood products" , and "harvest rates" are all plural and cannot be antecedent of it in any case. To me (A) looks better than (B).

Can someone throw light here why efficiency in is better than efficiency of.

There's not that much difference in the words but what follows them

Efficiency of is used in ' efficiency of harvested trees'... implying that harvested trees were doing something and have become more efficient

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.

GMATNinja & GMATNinjaTwo, Could you help to explain the difference between "efficiency in" and "efficiency of"? What is the pronoun "it" referring to? Does pronoun "it" refer to "improved efficiency"?

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.

Although there is idiom error in choice C,D and E
never eliminate solely because of the idiom error look for the other error as well
In choice D usage of being is not correct
in C and E which boost here which refers to prices which is not correct
Same error is repeated in B

So A is the best answer

In converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices,
Before concluding that a pronoun has reference problems, we have to see whether possible contenders tally in number with the pronoun. In this case, 'it' cannot refer either to trees or products or rates, as all of them are plural and the only eligible contender is 'efficiency'. This is one of the clearest cases of pronoun reference

B, on the contrary, has a serious modifier issue. We start with a modifier" Although in converting ….' and then what is followed is not the noun that does the action of converting. It is some obscure 'demand". Therefore, B essentially suffers a misplaced modification. On top of it, the passive voice main clause makes it murkier.

May Take: B

A. awkward - pronoun it refers to improved efficiency, and adverbial phrase thereby boosting consumption modifies verb stimulate wrongly implying that the demand stimulation due increased efficiency, instead of low prices, boost the consumption.
That is, line-of-reasoning is somewhat like this: increased efficiency > stimulate demand > boost consumption.
Correct line of reasoning is increased efficiency > increase supply > lowers prices > boost consumption > stimulate demand
C. Unidiomatic - efficiency of converting
D. passive, changes meaning
E. awkward - use of when, and missing improved efficiency - changes meaning

because of something....will never be correct on the gmat

it is: due to bla bla bla..... bla bla bla

(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.

(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.

====================================
A-) No errors.
B-) because of is wrongly used.
c-) Of converting is redundant. Also Boosts is wrongly used.
d-) OF harvested trees and Being is wrongly used.
E-) When harvested trees - New clause is introduced.

1 doubt - Cann't its be "efficiency of" as we use it on day today basis. Please give a strong point when to use efficiency of ???

Kudos if it helps anyone.

Hi experts,
Can you please throw some light on why OA is A ? Can somebody please explain?

My take:
A: Suspicious of "it" referring to efficiency . Also, "boosting" modifying preceding clause action, "stimulating demand" does not look correct to me. But this is 2nd best choice for me after D.
B,E : "because of increasing supply and lowering prices" looks wierd to me....According to me, "because of" should be followed by Noun/Noun phrase
C: "which boosts" is incorrect because even if we take just "prices", it should be plural as well.
So, I think answer should be D.

A and B are those that finally stand. I choose A because the answer adds clarity that "Improved efficiency" (it) will stimulate demand by increasing supply and lowering prices. Option B says that demand will be stimulated because of increased supply and lowering prices; it says nothing about Improved effeciency.

'It' clearly refers to 'improved efficiency'. Logically, neither harvested trees, nor wood products can't stimulate demand

Between 'A' and B':

A: is the Right Answer as its a pronoun exception : Pronouns which may be clear by virtue of meaning but the reasonable pronoun may have some other reference/ nearby antecedent and still be correct. So by Virtue of meaning A is clear.

Whereas,

B: is Passive in construction and the term "Although" in the beginning doesn't quite match to it.
