Identify the sentence with correct subject-verb agreement.

The choice that demonstrates correct subject-verb agreement is that the flowers bloom in spring. In this sentence, the subject "flowers" is plural, and the verb "bloom" is correctly conjugated to match that plural subject. In standard English grammar, it is important for the verb to align in number with its subject; plural subjects require plural verbs.

The other sentences have discrepancies between their subjects and verbs. For example, "The team are winning the game" mistakenly uses the plural verb "are" with the collective noun "team," which is typically treated as a singular entity in American English. Similarly, "The cars is parked outside" features a singular verb "is" paired with the plural subject "cars," which is incorrect. Finally, "The cat sleep on the bed" incorrectly uses the plural form "sleep" for the singular subject "cat" instead of the appropriate singular verb form "sleeps."
