Question

Identify the sentence that has correct subjectdash–verb agreement.

Answer 1

The answer to your question would be that the sentence that has a correct subject dash-verb agreement is the following one: Neither of those cars gets good mileage. That is, the correct option would be B.

When "neither" is used as a pronoun and as the subject of the sentence or clause (and it's the only subject), it takes a singular form.

Answer 2

"neither" requires a singular form: so a) is wrong.

b) is correct!

c) has the problem that "got" is the past of "get" and -s ending cannot be added to the past- incorrect!

d) actually it's also correct (but b is better) - this structure used for emphasis that the statement is true.
