Jeremy fell asleep while Babs read the story what type of clause is shown in parentheses?

The clause in parentheses "(while Babs read the story)" is an adverbial clause.

Here's why:

* Adverbial clauses modify verbs, adjectives, or other adverbs. They answer questions like "when?", "where?", "why?", "how?", etc.

* In this sentence, the clause tells us when Jeremy fell asleep. It modifies the verb "fell asleep".
