1- The stress syllables are used to highlight the important words and concepts as in <em>To </em><em>speak</em><em> of </em><em>that </em><em>which </em><em>gives</em><em> thee </em><em>all </em><em>thy </em><em>might</em><em>? </em>(bold-faced parts are the stress syllables).
2- The (mostly) regular rhythm does highlight the overall emotional weight on the poem, just try it by reading it out loud as the stress syllables are easy to identify.

The language system is semantics. "Coke" v.s "Sprite." are two different words, so we are focusing on a word. When Anna paused, she was confused because to Melinda, A Coke means a Sprite in her vocabulary. She wanted to confirm the same meaning. Semantics involves a changing meaning depending on the person. She is visiting from Alabama, so the meanings may have chosen just like dialects. Thus, it cannot be phonology/morphology, syntax, or pragmatics.
