Respuesta :

The sentence that correctly uses the punctuation mark, semicolon (;) is, "The curtains were shredded and all over the room; my cat looked very guilty." This is an example of a compound sentence. A compound sentence consists of two independent clauses. If we use a semicolon to separate the two independent clauses, then we do not have to use any conjunctions to connect both. 

The correct sentence using semicolon is the following: The curtains were shredded and all over the room; my cat looked very guilty.There're two independent clauses and an example of compound sentence.  Express a complete thought and have the same level of importance.
