Are complex sentences really complex? Not at all! Study the guide carefully, then practice them all!
A complex sentence is like a superhero and their sidekick teaming up to fight a villain. The superhero, an independent clause, is strong enough to work alone, but where's the fun in that? The sidekick, a dependent clause, needs help, so they use a subordinating conjunction to join forces with the superhero. Keep this analogy in mind as you tackle the challenge.
