* Dependent adverbial clause: Because the weather was stormy
* Independent clause: We decided to stay inside and play board games.
Explanation:
* The dependent adverbial clause "Because the weather was stormy" provides the reason for the independent clause.
* The clause is dependent because it cannot stand alone as a complete sentence. It requires the independent clause to make sense.
* The clause functions as an adverbial modifier, modifying the verb "decided" in the independent clause.
This sentence is complex because it contains one independent clause and one dependent clause.
