What is an example of a compound sentence?

A compound sentence is characterized by the presence of multiple independent clauses that are joined by coordinating conjunctions (such as 'and,' 'but,' or 'or') or punctuation like a semicolon. The definition inherently implies that each independent clause can stand alone as a complete sentence, making the overall structure more complex than a simple sentence, which contains only one independent clause.

In this context, option C correctly identifies a compound sentence as one that includes multiple independent clauses. This allows for the formation of more complex ideas and connections between statements, enhancing the richness of language and writing. It highlights how two or more complete thoughts can be linked together, providing greater depth in writing.

The other options do not accurately describe a compound sentence. For example, a sentence containing only one idea is a simple sentence, while a sentence with an independent clause and a dependent clause describes a complex sentence. A sentence that expresses a complete thought could refer to either simple, compound, or complex sentences but does not specifically define a compound structure. The understanding of what constitutes a compound sentence is essential for clear and effective writing, emphasizing the ability to convey interconnected ideas.
