Read the passage.All the students signed a petition, but they still needed the faculty’s permission to start the club. The students came to the next faculty meeting, and they presented a solid argument. All of their hard work paid off because the students won their campaign.

The first sentence is compound: “All the students signed a petition” and “they still needed the faculty’s permission” are independent clauses joined by “but.” The second sentence is also compound because its two independent clauses are joined by “and.” The third sentence is complex: “because the students won their campaign” is a dependent clause attached to an independent clause. So the passage contains two compound sentences and one complex sentence.
