My answer is (E).

(AB) can be eliminated relatively easily because "whether" should be used in the place of "if".

(C) For one, "whether ... might not initiate" is not as straightforward as "whether ... might initiate". If we can safely remove one word without jeopardizing the meaning of the sentence, it should be removed.
For two, because the rest of the sentence uses simple past tense "a program that increased productivity but polluted nearby rivers and streams", "might initiate" should be "might have initiated" to make more sense.

(D) Do we need "as to"? The answer is negative. Is it wrong to use "as to"? I am not sure. Yet, if we can safely remove some texts without jeopardizing the meaning of the sentence, they should be removed.
Also, "were to" indicates it is in subjunctive mood. For that reason, ”a program that increased productivity but polluted nearby rivers and streams“ had better be changed to "a program that would increase productivity but pollute nearby rivers and streams".

(E) This sentence does not use subjunctive mood. Those people simply wonder whether the unscrupulous industry wreaked havoc in the past.

For SC butler Questions Click Here


Those who are concerned about the environment question if the timber industry, interested in cost-efficiency, might not be initiating a program that increased productivity but polluted nearby rivers and streams.


A) question if the timber industry, interested in cost-efficiency, might not be initiating
might not initiating gives us a reasoning as though productivity schemes will never be introduced which is not the case therefore out

B) question if the timber industry, interested in cost-efficiency, had not initiated
if the scheme was never intiated there is no way of polluting which doesn't make much sense therefore out

C) question whether the timber industry, interested in cost-efficiency, might not initiate
Similar reasoning as A

D) wonder as to whether the timber industry, interested in cost-efficiency, were to initiate
were to intiate is a hot mess doesn't make much sense in addition dependent clauses are seperated through a lot of commas distorting therefore out

E) wonder whether the timber industry, with its interest in cost efficiency, initiated
THe meaning is perfect therefore our answer

THerefore IMO E

use of "if" is wrong here as sentence isn't conditional .A ,b out

C) question whether the timber industry, interested in cost-efficiency, might not initiate
sentence is in past tense. "might not initiate" should be following the same. incorrect

D) wonder as to whether the timber industry, interested in cost-efficiency, were to initiate
"were to initiate"?? slightly changes the meaning.

E) wonder whether the timber industry, with its interest in cost efficiency, initiated
seems fine
IMO E

Correct Option E

- Use “if” in a conditional sentence to show that one thing will happen if something else happens.
- Use “whether” to show that two alternatives are possible

Here in original sentence, flaw is with IF usage, because there is no condition implemented
Eliminate A, and B.

C is something about redundancy, whether and might both usage are similarity, to seek possibility.
- Whether initiate, yes or no?
- Might initiate, yes or no?
Plus add-on word "question" seek similar information.
Eliminate C

Between D, and E
It's the intended meaning of the sentence, meaning says,
"Environment concern people were surprised or wonder that Timber industry has talent to raise a program
to increase its cost efficiency
to increase its productivity
but has not initiated a program
to save river by getting polluted"

Option D creates flaw by
- usage of "were" plural verb for singular Noun "Timber industry"
- interested - Past tense, and we need interest in - present tense.
- "to initiate" refers to simple present tense, which indicates a program to begin in some time in future, but intended meaning says initiated program was suppose to make to people wonder.
- lastly usage of "As to" means "with regard to" or "about.", refering it to "whether" creates ambiguity.

This makes option D flaw to present itself with intended meaning of the sentence, makes option D wrong and option E correct.

Option D
Those who are concerned about the environment question wonder as to whether the timber industry, interested in cost-efficiency, were to initiate a program that increased productivity but polluted nearby rivers and streams.

Option E
Those who are concerned about the environment question wonder whether the timber industry, with its interest in cost efficiency, initiated a program that increased productivity but polluted nearby rivers and streams.

Dear Friends,

Here is a detailed explanation to this question-
generis


Those who are concerned about the environment question if the timber industry, interested in cost-efficiency, might not be initiating a program that increased productivity but polluted nearby rivers and streams.


A) question if the timber industry, interested in cost-efficiency, might not be initiating

B) question if the timber industry, interested in cost-efficiency, had not initiated

C) question whether the timber industry, interested in cost-efficiency, might not initiate

D) wonder as to whether the timber industry, interested in cost-efficiency, were to initiate

E) wonder whether the timber industry, with its interest in cost efficiency, initiated

Concepts tested here: Tenses + Idioms + Awkwardness/Redundancy

• “if” is used to refer to phrases that lead to a “then” clause and “whether" is used for showing alternatives; "whether" generally wins over "if" on GMAT.
• Past perfect tense (marked by the use of helping verb "had") is used when a sentence contains two actions in the past; the helping verb "had" is used with the action in the "greater past"
• The simple present continuous tense is used to refer to actions that are currently ongoing and continuous in nature.
• The simple past tense is used to refer to events that concluded in the past.
• The simple future tense is used to refer to actions that will take place in the future.
• The "were + infinitive verb form" construction is only used to refer to hypothetical past actions.

A: This answer choice incorrectly uses the simple present continuous tense verb "be initiating" to refer to an action that concluded in the past; please remember, the simple past tense is used to refer to events that concluded in the past, and the simple present continuous tense is used to refer to actions that are currently ongoing and continuous in nature. Further, Option A incorrectly uses "if" to show alternatives; please remember, “whether" is used for showing alternatives, and “if” is used to refer to phrases that lead to a “then” clause. Additionally, Option A uses the needlessly wordy phrase "might not be initiating", leading to awkwardness and redundancy.

B: This answer choice incorrectly uses the past perfect tense verb "had not initiated" to refer to an action that concluded in the past; please remember, the simple past tense is used to refer to events that concluded in the past, and the past perfect tense (marked by the use of helping verb "had") is used when a sentence contains two actions in the past; the helping verb "had" is used with the action in the "greater past". Further, Option B incorrectly uses "if" to show alternatives; please remember, “whether" is used for showing alternatives, and “if” is used to refer to phrases that lead to a “then” clause. Additionally, Option B uses the needlessly wordy phrase "had not initiated", leading to awkwardness and redundancy.

C: This answer choice incorrectly uses the simple future tense verb "might not initiate" to refer to an action that concluded in the past; please remember, the simple past tense is used to refer to events that concluded in the past, and the simple future tense is used to refer to actions that will take place in the future. Further, Option C uses the needlessly wordy phrase "might not initiate", leading to awkwardness and redundancy.

D: This answer choice incorrectly uses the "were + infinitive verb form ("to + initiate" in this sentence)" construction to refer to an event that concluded in the past; please remember, the simple past tense is used to refer to events that concluded in the past, and the "were + infinitive verb form" construction is only used to refer to hypothetical past actions. Besides, Option D uses the needlessly wordy phrase "wonder as to", leading to awkwardness and redundancy.

E: Correct. This answer choice correctly uses the simple past tense verb "initiated" to refer to an event that concluded in the past. Further, Option E correctly uses "whether" to introduce alternatives. Additionally, Option E is free of any awkwardness or redundancy.

Hence, E is the best answer choice.

Those who are concerned about the environment question if the timber industry, interested in cost-efficiency, might not be initiating a program that increased productivity but polluted nearby rivers and streams.


A) question if the timber industry, interested in cost-efficiency, might not be initiating
if is for condition and whether is for choice/option. whether usage is correct here. "initiating" is present continuous while increased/polluted ( which happened later) is in past tense. Eliminate


B) question if the timber industry, interested in cost-efficiency, had not initiated
if is for condition and whether is for choice/option. If usage is incorrect. Eliminate

C) question whether the timber industry, interested in cost-efficiency, might not initiate
"initiate" is present tense while increased/polluted ( which happened later) is in past tense. Eliminate

D) wonder as to whether the timber industry, interested in cost-efficiency, were to initiate
'as to' is redundant. "initiate" is present tense while increased/polluted ( which happened later) is in past tense. Eliminate

E) wonder whether the timber industry, with its interest in cost efficiency, initiated
The sentence is in past tense, and the choice uses past tense correctly. 'wonder whether' is idiomatically sound correct.
Hence the choice that is correct is E.

IMO E

"IF... then" conditional cannot be used in the sentence since it is not a conditional sentence and we will prefer "whether". Eliminate A and B

C) question whether the timber industry, interested in cost-efficiency, might not initiate - Need might have initiated for the overall tense to make sense.

D) wonder as to whether the timber industry, interested in cost-efficiency, were to initiate- Redundant.

E) wonder whether the timber industry, with its interest in cost efficiency, initiated - Correct Answer.
