Explanation:

Question 9

To determine if the subject is singular or plural, we look at the subject "circus performers". "Performers" is the plural form of "performer", and the verb "lead" is also in the base form (used with plural subjects in present tense). Also, "lives" is plural. So the subject and related elements indicate a plural subject.

The subject here is "Marita's best qualities". "Qualities" is the plural form of "quality", and the verb "were" is the plural form of the be - verb (used with plural subjects in past tense). So the subject is plural.

Answer:

B. plural
