Compare two texts within the same genre to identify shared genre conventions and how each text uses them differently.
Every genre has conventions -- common features readers expect. Historical fiction usually has a real setting and a coming-of-age problem. Mysteries usually have clues, suspects, and a reveal. Fables usually have animal characters and end with a clear lesson about behavior.
Comparing two texts in the SAME genre shows you which features are truly shared, the genre rules, and which choices are unique to each author. This is a more advanced comparison than just comparing plot -- you are comparing HOW each author uses the same toolbox.
Mastery looks like: They identify at least one true shared genre convention and one meaningful point of difference between two same-genre texts, with evidence from both.
Common stumbles: Comparing only surface plot details ("both have a fox") instead of genuine genre conventions such as structure, purpose, or character types.
