COMMA

Definition
a punctuation mark (,) indicating a pause between parts of a sentence. It is also used to separate items in a list and to mark the place of thousands in a large numeral.

Explanation: The comma sets off the introductory dependent clause that serves to describe they. As you will notice from your reading and writing, when a clause begins with a subordinate conjunction, it nearly always is followed by a comma.
