Is this a compound or complex sentence and tell me if it is cc or sc

Question

The choir won many awards because they are really good

Answer 1

This is a complex sentence. It is not a compound sentence as it does not contain two independent clauses connected by a coordinating conjunction (such as "and" or "but"). It is a complex sentence because it consists of one independent clause ("The choir won many awards") followed by a dependent clause ("because they are really good").
