Sentence Correction: Subject Verb Agreement Questions - Overview

Following a $200,000 grant from the Department of Homeland Security, there are now one surveillance camera for every 30 residents in Dillingham, a small town in Alaska.

Incorrect.

This answer choice is grammatically incorrect. The plural verb are does not agree with the singular subject one camera.

[[snippet]]

Incorrect.

This answer choice repeats original Subject Verb Agreement mistake: the plural verb are does not agree with the singular subject one camera.

[[snippet]]

Incorrect.

While this answer choice corrects the original Subject Verb Agreement mistake, it doesn't stop there and changes the plural noun residents to the singular resident.

This change produces an illogical sentence, as we cannot use the singular when we are discussing a total of 30 residents. This must be stated with the plural noun to be logical.

Very good!

This answer choice corrects the original Subject Verb Agreement mistake, by changing the plural verb are to the singular verb is, to match the singular subject surveillance camera.

[[snippet]]

Incorrect.

This answer choice is grammatically incorrect as there is no verb in the entire sentence. Every Sentence Correction sentence must include both a subject and a verb.
