Answer:
1/2
Step-by-step explanation:
The answer to your question would be that the sentences that contain an adverb clause are the following ones: "Darla set up a studio because she enjoyed painting" and "As Aaron was having a midnight snack, he heard a loud noise coming from the basement". That is, your answer would be options 1 and 2.
An adverb clause is a group of words that functions as an adverb in a sentence. They are dependent clauses so, as such, they must have a subordinating conjunction to connect them to the rest of the sentence. In this case, the subordinating conjunctions connecting the dependent clauses to the rest of the sentence are the following ones: As (introducing information about time) and because (introducing the reason why Darla set up a studio).
