Question

The following is an example of a ________ sentence.

Answer 1

Before watching the game, Skylar made artichoke and spinach dip, as well as super nachos.

That sentence contains an independent clause: Skylar made artichoke and spinach dip. 
As well as two dependent clauses: Before watching the game; as well as super nachos.

Given those characteristics, I believe that sentence is complex.
