+1 for B

Split 1:

We need to use Such as for examples. Only A, B and C follow. Hence, eliminate D and E

Split 2:

We have a idiom usage Not only X but also Y. Here, X and Y must be parallel (Not only using but also reducing). Hence, Eliminate A and C

A. as carbon dioxide and methane to the atmosphere have recommended not only that home appliances should be used judiciously but also reduction of : Not only X but also Y, parallelism error.
B. as carbon dioxide and methane to the atmosphere have recommended not only using home appliances judiciously but also reducing : CORRECT
C. as carbon dioxide and methane to the atmosphere have not only recommended using home appliances judiciously but also reduction of : Error same as in A
D. like carbon dioxide and methane to the atmosphere have recommended not only using home appliances judiciously but also reducing : After like, need a clause, to give example, use 'such as '
E. like carbon dioxide and methane to the atmosphere have not only recommended using of home appliances judiciously but also reduced : Error same as in D.

Like cannot be used as it imainly used for comparison, so D and E are out.

For giving examples we use such as, Removed D and E

Now in A, B and C , removed A and C

B is parallel in using the correct idiom not only using... but also reducing...

Correct Answer is B

D. like carbon dioxide and methane to the atmosphere have recommended not only using home appliances judiciously but also reducing
E. like carbon dioxide and methane to the atmosphere have not only recommended using of home appliances judiciously but also reduced


Official Explanation:



Meaning Analysis:
The sentence talks about major studies that have been conducted to research ways to reduce the carbon footprints from sources that add gases such as carbon dioxide and methane to the atmosphere.

These studies have recommended:

1. not only using home appliances judiciously
2. but also reducing emissions from automobiles.

Error Analysis:
This sentence uses the dual word parallel marker “not only X but also Y” in which X and Y should be both logically and grammatically parallel. Here X is “that home appliances that should be used judiciously” and Y is “reduction of emissions from automobiles”. The clause beginning with the relative pronoun modifier “that” is not parallel to the noun phrase “reduction of…”

Answer Choices
A. as carbon dioxide and methane to the atmosphere have recommended not only that home appliances should be used judiciously but also reduction of

Incorrect: This choice has the error pointed out in the error analysis.

B. as carbon dioxide and methane to the atmosphere have recommended not only using home appliances judiciously but also reducing

Correct: This choice corrects the parallelism error of Choice A by making X = using home appliances…” and Y = “reducing emissions…”

C. as carbon dioxide and methane to the atmosphere have not only recommended using home appliances judiciously but also reduction of

Incorrect: The placement of “not only” before “recommended” leads to a logical as well as grammatical parallelism error. As per the original sentence, the studies have recommended two things: not only X but also Y. So, “recommended” should be placed before “not only.” Also, the verb “recommended” is neither logically nor grammatically parallel to the noun “reduction”.

D. like carbon dioxide and methane to the atmosphere have recommended not only using home appliances judiciously but also reducing

Incorrect: This choice uses the incorrect idiom “such like” to present examples. The correct idiom is “such as”.

E. like carbon dioxide and methane to the atmosphere have not only recommended using of home appliances judiciously but also reduced

Incorrect:
1) This choice completely distorts the intended meaning. The verbs “recommended” and “reduced” appear grammatically parallel, but there is no intended logical parallelism between these two entities. As explained in the POE for Choice C, “not only” cannot be placed before “recommended” in this context. Also, this choice indicates that the studies performed two actions: “recommended” and “reduced”. It is completely illogical to state that the studies reduced emissions.

2) This choice retains the “such like” idiom error of Choice D.

3) The phrase “using of home appliances” is idiomatically incorrect. The idiomatically correct phrase is “using home appliances”.
