Question 4

C. He liked to cook at home, but she preferred to eat at restaurants.

A compound sentence is formed when two independent clauses are joined by a coordinating conjunction. Option C exemplifies this structure as it contains two independent clauses: "He liked to cook at home" and "she preferred to eat at restaurants," connected by the conjunction "but."

A) After playing basketball all day, the girls were very tired.

This sentence is a complex sentence, not a compound one. It contains a dependent clause ("After playing basketball all day") and an independent clause ("the girls were very tired"), which does not fulfill the requirement for a compound structure.

B) Although he would have gone to the movie that his friends recommended, it started too late.

This option also represents a complex sentence. It includes a subordinate clause ("Although he would have gone to the movie that his friends recommended") and an independent clause ("it started too late"). Therefore, it does not qualify as a compound sentence.

C) He liked to cook at home, but she preferred to eat at restaurants.

This option is indeed a compound sentence. It effectively combines two independent clauses with the coordinating conjunction "but," demonstrating a clear compound sentence structure.

D) The professor enjoyed reading, cycling, and listening to jazz music.

This sentence is a simple sentence with a compound predicate. It lists multiple activities enjoyed by the professor but does not contain two independent clauses joined by a coordinating conjunction, thus failing to meet the criteria for a compound sentence.

Conclusion

Option C is the only choice that correctly represents a compound sentence structure, featuring two independent clauses linked by a coordinating conjunction. Options A, B, and D either exhibit complex structures or simply list multiple items, failing to create the necessary combination of independent clauses. Therefore, C is definitively the correct answer.
