Skill 24: Use parallel structure with coordinate conjunctions

The job of the coordinate conjunctions (and, but, or) is to join together equal expressions. In the other words, what is on one side of these words must be parallel to what is on the other side. These conjunctions can join nouns, or verbs, or adjectives, or phrases, or subordinate clauses, or main clauses; they just must join together two of the same thing.
