Parody mocks or imitates aspects of another work for pure entertainment, without serious commentary. In contrast, satire uses humor and exaggeration to ridicule societal issues and institutions in order to promote social or political change.

The document then asks the reader to analyze advertisements to determine if they use parody, satire, or both.
