Explanation: A conjunctive adverb is a type of adverb used to connect an independent clause to another independent clause. <u>In the first sentence</u> ("Dogs are affectionate pets; on the other hand, cats are not very loving; however, owning a cat does have other advantages"),<u> there are two conjunctive adverbs: "on the other hand" and "however"</u>. Both of them show contrast. Furthermore, a subordinating adverb or conjunction is a word used to connect an independent clause to a dependent clause. <u>In "Although we left our house an hour before the time of the show, we did not arrive on time because our car broke down", "although" and "before" are subordinating conjunctions</u>. "Although" indicates concession, while "before" makes reference to a relationship of time. Finally, correlative conjunctions are conjunctions that come in pairs and connect one element to another<u>. In the third sentence</u> ("Neither Sarah nor her brother will go to the party tomorrow night"), <u>"neither... nor" and "not...but" are correlative conjunctions.</u>
