Before doing the exercise, let’s go over a few grammar terms:
Clause – a group of words that contains a subject and a verb.
Independent clause – a clause that expresses a complete thought. Also called a sentence.
Dependent clause – a clause that does not express a complete thought, and therefore must be connected to an independent clause.
Subordinating conjunction – a word that introduces a dependent clause. A comma is required after a dependent clause when it comes before an independent clause.
Choose the correct subordinating conjunction to complete each sentence.
