Which type of sentence includes one independent clause and at least one dependent clause?

The correct response identifies a complex sentence, which is characterized by having one independent clause and at least one dependent clause. In a complex sentence, the dependent clause cannot stand alone as a complete thought; it is dependent on the independent clause to provide meaning. This structure allows for the expression of more nuanced ideas and relationships between different parts of a sentence, enhancing both clarity and depth in writing.

In contrast, a simple sentence consists solely of a single independent clause, making it straightforward and without any added complexity. A compound sentence, on the other hand, includes two or more independent clauses joined by a coordinating conjunction, while a compound-complex sentence combines elements of both, containing at least two independent clauses and at least one dependent clause. Understanding the distinctions among these sentence types is crucial for effective writing and communication.
