Final answer:
For the given sentence, 'Maybe Quentin Lance is running late to the movie' is correct, as 'maybe' is an adverb used to express possibility or uncertainty.
Step-by-step explanation:
In the sentence provided, the correct form to use is "maybe," which is an adverb meaning "perhaps" or "possibly." So, the correct sentence would be "Maybe Quentin Lance is running late to the movie." The term "may be" is a verb phrase that is used differently, to indicate the possibility that someone or something 'is.'
For example, "Quentin Lance may be the person who borrowed your car." In the context of Quentin Lance running late, since the intention is to express uncertainty, maybe is appropriate.
