Passage Summary: Romance and satire characters stay the same to match their worlds, but comedy and tragedy characters must change, so they can't be the same thing.

Conclusion: Tragedy and comedy are distinct categories that cannot be considered romance or satirical literature.

Reasoning: Romance and satire involve characters whose morals reflect their static worlds, whereas tragedy and comedy require characters whose morals change.

Analysis: There is a gap between 'reflecting a world' and 'changing moral qualities.' The critic assumes these two things are mutually exclusive. To guarantee the conclusion, look for an answer that bridges this gap by stating that if a character's moral qualities change, they cannot reflect their world in the way required by romance or satire.
