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.

There is absolutely nothing wrong with option A.

Option B - Demand will be stimulated by increasing supplies and lowering prices - right .. who exactly will do this - my grandfather ?

more over, this is in passive voice and the right way of putting even this passive voice is 'demand will be stimulated by the increased supplies and the lowered prices'.

B clearly wrong, Agree with Pleo that "his grandfather" may exactly do that

Ok to add on to the mystery of "thereby" I have another question. This is from Kaplan and I am confused about the correct usage of 'thereby', 'and so', 'which' in any sentence. If somebody can please clarify for me, it will certainly help.

Question: A common social problem in the workplace occurs when workers accept supervisory positions, and it causes them to lose the trust of their former co-workersC

A. when workers accept supervisory positions, and it causes them to lose
B. by a worker accepting supervisory positions, which causes him to lose
C. when workers accept supervisory positions, and so lose
D. when a worker who accepts a supervisory position, thereby losing
E. if a worker accepts a supervisory position, he would lose

Vote for A

This is a very tough one. I got all confused between A and B because both have no clear antecedent.
- improved efficiency VS efficiency
- lowering prices, or both.

Eventually pick A because, at least, Although X ..., X ... is more concise and parallel.

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.

How can the answer be B. OA must be A for similar reasons discussed above.
Rightly said by daagh that if the answer is from OG or GPrep then we have to accept otherwise kick the source of this question.

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

Guys..Wanted to know if this can also be a reason to eliminate B

If we look at the second part, it looks to me like an independent clause

"demand will be stimulated because of increasing supply and
lowering prices, which boost consumption"

I mean it clearly does not require previous clause to support it. if we say that the demand will stimulate because..bla bla bla..it will still make sense.

in that case since B is connected just by a comma, thus it can be incorrect
am I right in my understanding?

"because of" refer to an agent which do not directly cause the action
"by" refer to an agent which directly cause the action.

that is reason why, b, e is wrong

is my thinking correct?

Hi E-GMAT,

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.

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

I also took B because it eliminates "it" problem and does clause sentence with "although" conjunction and comma. Nothing wrong with "which", it has immmediate antecedent "lowering prices, which boost consumption"
