This was a question asked in our last test

Either of her eyes --------- not work well.
(Do, does, is)
I answered 'do' but some of my friends say 'does' is the correct answer. Now I am really confused. Please someone help.
What's the correct answer???

Either is singular so must take a singular verb.

Either . . . does . . .

The better way to say this is

"Neither of her eyes works right."

Thank you so much. Now I got some relief.

Oh did I type I answered do? I am sure I answered does and my friend s said do

That was a brain fade. Typo

To determine the correct answer, let's break down the sentence: "Either of her eyes ____ not work well."

In this sentence, we are talking about a singular subject, "Either of her eyes." Since we are referring to a single eye at a time, we need to use the singular form of the verb.

To determine whether to use "do," "does," or "is," we need to consider the subject-verb agreement in the present tense.

The verb "do" is used with plural subjects and the pronouns "I," "you," "we," and "they." For example: "I do my homework every day."

The verb "does" is used with singular subjects and the pronouns "he," "she," and "it." For example: "She does her laundry on Saturdays."

The verb "is" is used as a linking verb in sentences with a subject complement. It is not appropriate in this context.

In our given sentence, since we are talking about "either of her eyes" as the subject, which is singular, the correct verb to use is "does."

Therefore, the correct answer is "does."
