A compound sentence<span> is made up of two or more simple sentences joined with a conjunction.</span> Complex sentences must
include at least one
dependent clause
introduced by a
subordinating conjunction
or a relative pronoun and
an independent clause. A compound-complex sentence has one complex
sentence joined to a simple sentence with a
conjunction.
Therefore, the sentence, <span>"because our favorite restaurant was closed, we decided to cook dinner at home." is a complex sentence. This is the correct answer because the dependent clause, "because our favorite restaurant was closed" was introduced by the </span>subordinating conjunction, "because". It also has an independent clause, "we decided to cook dinner at home."
