Argumentation
The most common major rhetorical-mode pattern you may find in college readings is argumentation. It is common because many textbooks and other assignments you will read in college--especially in the humanities, liberal arts, and social sciences--are arguing a point.
Argumentation as Overall Structural/Controlling Mode
Introduction: Issue or Main Argument. Possible use of definition (which includes comparison/contrast and example), statement of overall cause and effect, and/or other modes
Body: A Series of Points Helping to Prove the Main Argument
Each Longer Paragraph:
(1) statement of a point providing a part of the proof
(2) development of the proof with detail using exemplification, narration, cause and effect, and/or other modes
Conclusion:
Concluding Argument. Possible use of description, cause and effect, narration, and/or other modes.
