Explanation:
An adverb clause is a group of related words that have at least a subject and a verb, and whose function is to modify or add detail to adjectives, verbs or other adverbs.
This type of clause often answers questions such as "Why?", "How?", "When?", "Where?" and "In what circumstances?", and they are always introduced by a subordinating conjunction such as because, since, as, while, though, even though, after, as long as, before, even and until.
In sentence 1, because she enjoyed painting is the adverb clause because it gives further detail of the action "set up" and it also answers to the Why question: Why did Darla set up a studio? Answer: Because she enjoyed painting.
In sentence 2, As Aaron was having a midnight snack is the adverb clause because it gives further detail of the action "heard" and it also provides information of when or in what circumstances Aaron heard a loud noise coming from the basement.
