A group of words that includes a subject and a verb but does not express a complete thought is called subordinate clause, or also referred to as dependent clause. This group of words is not a sentence and can't stand alone as a sentence. Example : Because I can't wait for the bus; Until the sun rises.
Just concentrate and don't think anything but just focus in amswering your assignment. Don't mind the people sorrounding you.
