Explanation:
Independent clauses are complete clauses that can stand on their own, but when they are next to coordinating conjunctions or conjunctive adverbs, they form a compound sentence. These five examples have two independent clauses. For instance: "Rich people waste a lot of money" and "poor people barely have food for the day" make sense on their own; however, the conjunctive adverb "meanwhile" connects and contrasts them.
