Final answer:
The common nouns in the sentence are 'band', 'park', 'festival', and 'June.' 'Band' can also be a collective noun and takes a singular or plural pronoun depending on context.
Step-by-step explanation:
The student's question was about identifying common nouns in the sentence "Band play in Grant park during the festival in June." In English grammar, common nouns are words that name general items rather than specific ones. In this case, the common nouns are band, park, festival, and June.
These nouns are not capitalized unless they start a sentence or are part of a title because they do not name specific places, people, or things. Additionally, talking about collective nouns, band could be a collective noun and can take a singular or plural pronoun depending on whether the band acts as a single unit or as individuals.
For instance, 'The band rehearses every day' uses a singular verb because the band is acting as a single unit, but you could say 'The band members loaded their instruments on the bus' to focus on their individual actions.
