Question

In which phrase does “some” refer to a singular noun?

a. some of the economy cars
b. some of the police force
c. some of the native people
d. some of the healthy foods

Answer 1

B, because in all other situations the nouns are plural and the phrase is referring to "the police force" as a whole figure, and "some of the police force" is describing a fraction of this larger whole and would still be singular.
