I think there may be a distinction between 'efficiency in' and 'efficiency of'. But I can't put my finger on it. Can somebody explain the difference (if any)?

I vote for A.

You have to have efficiency in something so eliminate C, D, and E. B is incorrect because it doesn't identify what stimulates the demand.

A remains.

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

IMO 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.

A. in converting harvested trees into wood products may reduce harvest
rates, it will stimulate demand by increasing supply and lowering prices,
thereby boosting -->it here is not clearly referred to any Noun

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 --> the best. No existence of unclearly referred pronoun

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 error as A

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 -->same error as A.

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 --> the bold face is ungrammatical

B has "because" in it...doesnt the gmat prefer "due to" ? I would have gone with A. In A "it" is not ambiguous because it refers to the action "improved efficiency in...."

"It" may refer to the "improved efficiency in....", however you have to make a conscious effort to decide that it does. This effort is quick and not hard, but you have to make it. When you read the the choice A for the first time, I'm sure you experienced it.

One of the great things GMAT teaches is the elimination of ambiguity, however insignificant it might be. This problem is clearly a perfect example. GMAT teaches that you should not spend mental energy on deciphering word constructions of the author, but rather spend it on thinking over the meaning of what the words convey. It took me a bit of time to realize this, but once I did, it improved my sentence correction skill somewhat. That being said, I still got the wrong answer the 1st time around.

I'm certain B is the best choice here. All IMO, of course, and I'm not a native speaker.

I disagree with both A and B.
It has a referent issue:
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.
"it" may refer to harvest rates or improved efficiency.

The use of "which" creates ambiguity:
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" usually refers to the word / phrase immediately preceding it. In this case which refers to lowering prices, but in essence it should refer to both increasing supply and lowering prices.

C,D,E are out anyways. No Solution to this SC.

Limiting to just A and B:

As an accepted custom, in two –part sentences, a pronoun first refers to the subject of the sentence and if there is no appropriate subject for the pronoun, however distantly the subject may be placed, then the given pronoun will try to sticks on to the nearest noun. We have to conjecture that.

In A, the subject is clearly the improved efficiency which befits the pronoun.

Now B: The subordinate clause is in active voice, while the main clause is in passive voice. How parallel is this structure?

If this exercise is from OG or GPREP, then let us take the OA. Otherwise we are entitled to contest the OA.

A is the clear choice.

E. When harvested trees are converted into wood products may reduce harvest rates, demand will be stimulated because of increasing supply

Hi ishancrazee,

In this question C, D "efficiency of converting harvested trees" and "efficiency of harvested trees" are idiomatically incorrect. "When" in (E) is also not preferred because its use will imply of the efficiency at a particular time "when" harvested trees are converted into wood products.

A. in converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices,
thereby boosting.

(A) correctly uses the participle "boosting" to modify the previous clause, meaning that "boosting" is a result of "increasing supply and lowering prices". Moreover "in converting" usage is better than those in other answer choices.

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.

In (B) if you see the last part "which boost" it means that the verb "boost" should agree with a plural subject, which in this case seems to be "increasing supply and lowering prices". On the other hand, one might say "which" modifies the noun closest to it i.e. prices; this usage will be more preferred. But, even if we take this usage into consideration, we will change the meaning of the original sentence, which intends to say that both "increasing supply and lowering prices" are boosting 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.

Incorrect as explained above

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.

Incorrect as explained above

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.

Incorrect as explained above.

Hope this helps,

Vercules

Choice C and D uses preposition "of" which is incorrect
Choice E distorts the implied meaning of sentence and sounds fragment "Although improved efficiency when....."
Choice B - I notice a subtle linking verb parallelism error between "may reduce" and "will be stimulated"

the deal breaker here is not really "of" ."of converting " is not really wrong .the main issue with this B is "which" .the clause starting with "which" has to refer to complete previous clause so usage of "which" is wrong

now in D "Although improved efficiency Of harvested trees" is wrong

Hi Neha,

I differ slightly to your opinion:

Though prepositions have manifold usages, and mostly gets decided by context of sentence, it cannot be ignored as a "no grammar rule"

Through this official question, we understand the usage of "of". Preposition "of" is used to show possession. When we say "improved efficiency of", this improved efficiency must belong to something/someone.

But improved efficiency of harvested tree does not make sense. This is the reason why use of "of" is not appropriate

Use of "improved efficiency in converting" is correct because here improved efficiency has happened in doing some action. So we really need to understand the context of the sentence to be able to use correct preposition.

With regards to "which" yes it is indeed correct, however if I notice an error at the beginning of a sentence, it is good to probe further, but not worth taking time to do so.... that is my personal opinion - leave it or take it!

My queries is , Could you please explain the sentence structure of choice A mainly "thereby boosting ..." is it a modifier introducing a dependent clause or a independent clause marker?

Secondly , in choice B , Could you please explain the usage of "Because of increasing & lowering" structure , as "Because of Verb-ing seems a wrong usage in GMAT. Correct me where I'm wrong .

Thanks

Thereby is an adverb. In the stem, thereby (as an adverb) is modifying the preceding verbs - increasing and lowering. 'thereby boosting consumption' is indeed an adverbial (thereby is the adverbial conjunct)

The usage of increasing and lowering is wrong in option B. If you wanted to use -ing form, then it could have been written as
Because of an increasing/increased supply and a lowered price ....
In which case, increasing and lowered act as participles modifying the succeeding nouns.

And yes, Because of +ing form is valid. For ex. Because of swimming teacher, I was able to learn swimming much faster.
It is a perfectly valid sentence.

Note: 'Because of' is used as a preposition and 'because' is used as a subordinating conjunction

The option A meets all the parallelism points, hence it should be correct. But the second IT 'it will stimulate demand', is modifying harvest rates, not sure on this.
