### HideShow timer Statictics

While preliminary trials have shown marked improvements in blood pressure and blood sugar measurements among most test subjects, many researchers are concerned that the drawbacks to high costs and of serious side effects will limit the drug's economic success.

A)drawbacks to
B)drawback to
C)drawbacks of
D)drawback of
E)drawback of

In above question i selected answer choice 'D' while OA is 'C'
since high cost and side effects are two things i thought plural verb will be 'drawback' not 'drawbacks'

However in below example:-
She looks unhappy.<== here 'looks' is singular verb.

Can someone explain how to identify such kind of verbs?
[Reveal] Spoiler: OA

First of all 'drawbacks' is not verb here. The verb is 'limit', 'will' represents future tense.

Two things are checked here.
1. Drawback vs Drawbacks
2. of vs to

1.
While preliminary trials have shown marked improvements in blood pressure and blood sugar measurements among most test subjects, many researchers are concerned that the drawbacks to high costs and of serious side effects will limit the drug's economic success.

So to be parallel with the bold of, we would choose answer choices with of

2. What are the drawbacks?
>> high costs and serious side effects >>> Multiple issue >> Plural

So we will choose answer choice with drawbacks >> Plural.

Combining 1 and 2, Ans choice C is correct.

I want to know about singular and plural verbs ambiguity?
keeping parallelism aside.

Just to be clear again, here 'drawbacks' was not the verb.

This is very basic rule of subject verb agreement.

Use plural verb when subject is singular. Ex. Mike eats cake.
Use singular verb when subject is plural. Ex. Children eat cake.
