Final answer:
Circumstances prompting Ed to take rhetorical action may involve complex situational factors such as economic, political, or educational challenges, prompting him to use rhetorical strategies to persuasively address the specific concerns of his audience.
Step-by-step explanation:
The circumstances that prompt Ed to take rhetorical action might include a variety of situational factors, such as economic crises, budgetary constraints, educational needs, political platforms, or social demands. Rhetorical action starts with understanding these complex contexts and moving forward to create persuasive communication that effectively addresses the specific audience and their concerns. This might involve crafting arguments using rhetorical strategies such as logos, pathos, or ethos, and demonstration of the writer's intent either to conform to or challenge conventional expectations. It's crucial to consider if the context is pushing for such a move, like in the example provided where Greendale is likely experiencing a challenging situation pushing the writer or speaker to act rhetorically.
