Every morning, a group of hospital workers _________________
Which of the following options correctly completes the sentence above?

Question

Quizplus · Accepted Answer

A singular subject needs a singular verb, whereas a plural subject needs a plural verb.
Collective nouns are nouns that refer to a collection of people or things that are taken as a whole. One example of this is the word group. Even if information is provided about who or what is in the group (e.g. a group of students), the group is still being referred to as a single thing, the group.
In this sentence, the subject is "a group [of workers]", so it requires a singular verb (protests).
Other examples of collective nouns that would use a singular verb:
class of students
audience of people
a pack of wolves
