Question

subject verb agreement-. oil and water -------- not mix ( do / does )

Answer 1

Answer:

do

Explanation:

What is subject verb agreement?

It is a rule which decides which helping verb will come after the subject.

According to the subject and verb agreement if the subject is singular, we should use singular helping verb and if the subject is plural we should use plural helping verb.

Here in the given sentence both the mention subjects are different so we should use do after them.

They dont not indicate one particular entity so we should not use does.

Answer 2

The answer is: Oil and water do not mix.

This is because we use a plural verb (i.e. 'do') when the sentence's subject consists of two or more nouns or pronouns joined by 'and'.
