Answer:
All that is necessary to be done is to make the government consistent with itself, and render the rights of the States compatible with the sacred rights of human nature.
First off, a compound sentence is a sentence that contains at least two independent clauses. That tells us <em><u>C</u></em> is out almost immediately because it has a dependent clause, "After Maria finished dinner". Next, is <em><u>B</u></em>, That's a simple sentence, there's no joining method or comma and it only has one subject and one predicate. D isn't right either, it just about the same as <u><em>B</em></u><em />. Your answer would be <em><u>A. Paolo missed his girlfriend, but he knew she'd be back soon.</u></em><u /><u /> This sentence has a joining clause, and two <em>independent </em>subjects.
Hope this helps,
♥<em>A.W.E.<u>S.W.A.N.</u></em>♥
I'm not sure if there were specific answer choices but using complex words actually makes your statement rather unclear, especially assuming they are words the average person wouldn't know or understand.
