Test students' ability to apply discourse and cohesion analysis to identify and diagnose coherence problems in undergraduate academic essay excerpts and to propose targeted revisions. Items will require: (1) identifying discourse-level issues (rhetorical moves, macro-organization, topic-sentence alignment), (2) diagnosing cohesion breakdowns (reference, conjunctions, ellipsis, substitution, lexical chains), and (3) prescribing concise, actionable revisions (reordering content, rewriting topic sentences, adding cohesive markers, clarifying referents) with brief rationales tied to coherence principles.
