In this case, "reduce" and "aid" are not plural because you also have the auxiliary verb "may". This works for singular or plural subjects:

Hi saranshpuri,

Bill mentions an important point about the usage of the word "may", so you should store that away for future use.

As it stands, the GMAT tests a consistent set of grammar rules and idioms/style rules, so knowing what those rules are (and how they typically appear) can make answering most SCs a fairly straight-forward process. When I read this SC, I saw 2 things:

1) Modification: the word "significantly" is an "-ly" modifier, which is a grammar rule that you will be tested on. The word "significantly" must be placed next to the word that it's supposed to modify. In this case, it's the word "reduce" - the phrase "significantly reduce" is what we should be looking for. Eliminate B and D.

2) Parallelism: since we're looking at a "list of 2 things", we have to make sure that the 2 things are parallel (they must have the same format). Answer A uses the words "reduce" and "aid", which are parallel, BUT uses the phrase "and also" which is redundant. Eliminate A. Answer E uses the words "reduce" and "aiding", which are not parallel. Eliminate E. Answer C uses "reduce" and "aid"; this is parallel and has no other problems.

Final Answer: C

Hi Experts,

Can we consider "and" as plural subject here?

"And" creates a plural subject only when it is connecting two nouns:

The cat and the dog are friends.

Here, the "and" is connecting two verbs: may reduce and aid.
This is a parallel list of verbs that has a single subject: eating.

Thank you for the clarification Ceilidh. One more question:

I've read on the forums that using "are...ing" is wrong - how can it be corrected?

for eg:- Is the foll sentence wrong?

1. They are working in the factory (I know "they" has no antecedent; please ignore the pronoun error )
