I would love to answer this question but it looks like you need to attach a passage to answer this question. Btw the other answer that other person gave you was just to get points there is no file.
The answer is, "Subordinate clause."
A subordinate clause is also known as a dependent clause, which is the opposite of an independent clause. An independent clause is a part of a sentence that can stand on its own and can still technically be a valid sentence. A dependent clause depends on the main clause to form a complete sentence.
The best way to punctuate the sentence is: "We enjoyed perfect skiing weather," my friends told me. "The sun came out and the wind died down completely."
