Respuesta :
A sentence that has two or more main clauses and one or more subordinate clauses is called a compound-complex sentence. For example, Jessie reads novels, and Lucas reads poetry, but Gordon reads magazines because novels and poetry are difficult to comprehend. "Jessie reads novels", "Lucas reads poetry", and "Gordon reads magazines" are the independent clauses, while "because novels and poetry are difficult to comprehend" is the dependent clause.
Answer: A sentence with two or more main clauses and one or more subordinate clauses is a compound-complex sentence.
Explanation: A compound-complex sentence is a long sentence that joins two types of sentence: compound sentences and complex sentences. In that way, a compound-complex sentence includes two or more independent clauses and one or more dependent clauses. Independent clauses, which can stand alone as complete sentences, are joined by means of a coordinating conjunction, while dependent clauses, which do not express full ideas, are introduced by a subordinating conjunction. One example of compound-complex sentence is "Although we left the house early, we could not arrive to the concert in time, and we had to return home".
