Is closed a state of being verb in Snowfall the schools?

In the context of "Snowfall: The Schools," "closed" functions as an adjective, not a state of being verb. It describes the state of the schools (i.e., the schools are in a closed state). A state-of-being verb (like "is," "are," "was," "were") would be needed to make "closed" part of a verb phrase. For example, "The schools are closed" uses "are" as a state-of-being verb, with "closed" as a past participle functioning as an adjective within the predicate.
