Answer:
What makes the sentence a compound sentence is that it has at least two independent clauses and no dependent clause.
Explanation:
Where two or more independent clauses are contained in a sentence, it is known as a compound sentence. It also includes the use of a comma, semicolon and coordinating conjunctions like "and", "for", but, "nor', "yet", "so".
other examples of a compound sentence are, "I called Mary but she didn't answer her phone", "I winked at her and she smiled back at me", 'the light went off so I turned on the lamp".
