1. Expository* mode of presentation:
- prioritizing evidence and logic, separating facts and opinions;
- attempt to show subjective or even objective truth, explaining a concept, discourse to convey knowledge;
- using images to advance the argument, evidentiary editing, conceptualism, ideas over aesthetics;
- formal academic, business, technical, or scientific writing, argumentative speech or essay, monologue, tutorial, news story, review.
Exposition (setting forth of the meaning or purpose) sub-modes:
- Rhetoric: persuasion, reasoning, justification, warrant, strong argument and point of view;
- Analysis: relationships of ideas or parts, possible situations, alternative responses, systemic analysis, comparison, gaining insight;
- Critique: evaluation of worth or significance, questioning, methodical doubt with recognition of merit, judgement according to a set of standards, commentary, formal criticism, identifying possible desirable changes, implications and solutions, conclusions, and recommendations.
* Expository mode can mean almost the opposite under different approaches, I found. I went with a sort of evidence-based persuasion, also because it is almost impossible to produce a purely factual all-encompassing opinion-less non-bias creation.
