Final answer:
A speech with a balance of clarity, oral fluency, and rhetorical effectiveness that uses ethos, pathos, and logos, would likely be mostly informative and highly effective in communicating with an audience.
Step-by-step explanation:
Considering the information provided, a speech that would be diagrammed in the manner indicated seems to exhibit a balance of ethical appeal (ethos), emotional appeal (pathos), and logical reasoning (logos). This suggests that the speech would likely align with multiple rhetorical strategies to effectively communicate with an audience. The descriptions suggest that the speech and its outline have various degrees of clarity, fluency, and rhetorical effectiveness, which could lead to it being mostly informative while also successfully appealing to the audience's intelligence and sympathies.
The evidence of the writer's intent to meet or challenge conventional expectations in rhetorically effective ways, as well as the careful consideration of tone and language choices suited to the audience and purpose, could further classify the speech as highly effective. When a speaker strategically uses ethos, pathos, and logos, they are more likely to present a comprehensive argument that resonates with their audience on multiple levels, which is a hallmark of effective communication in rhetorical terms.
