Answer:
A number of people <u>are</u> concerned about the lack of progress.
Explanation:
Verbs in the English language agree with the subject of the sentence in number. “A number of people” is the subject, since they are the ones performing the action (expressing concern). Since “people” is plural, the correct form of the verb “to be” is “are”.
The non-finite verb would be “meaning” and I THINK it’s a Gerunds type of non-finite verb.
