With the culture standards, the student needs to master more complex expressions that have become essential to articulate the complex value systems in the social situation represented in the novel and in its society in general.  Such language use, unless conducted in response to class discussion, necessitates a verbal response of several sentences or at least a paragraph if a written response.  Moreover, to articulate the values expressed in texts, students must add to their extant language inventory several advanced capabilities: adverbial expressions of time (before / after the war), scalars for comparing qualities (a condition in the novel is better / worse for African-Americans), and markers for cause and effect ("because of [due to, as a consequence of] Melanie's insistence, Scarlett was accepted in antebellum society in Atlanta").  In this way the Standards predict the linguistic sophistication students will need to realize a particular reading objective.
