A complex sentence contains one independent clause and at least one dependent clause. Here, in your example, there are two simple independent clauses which you need to merge using a dependent adjectival clause in order to make one complex sentence. Here is how to do it:
The boy <u>who wore a green coat</u><u /> carried his sister home.
According to Aristotle, there are Six Element of Drama. These are:
1) Plot
2) Theme
3) Characters
4) Dialogues
5) Music/Rhythm
