What can be a consequence of poor rhetorical practice?

Miscommunication and misunderstanding can arise from poor rhetorical practice because effective communication relies on clearly conveying ideas and intentions to the audience. When rhetorical techniques are not applied effectively, it can lead to ambiguity, misinterpretation, and confusion regarding the speaker's message. This means that the audience may not grasp the intended meaning or may derive their own interpretations based on unclear or poorly structured language.

In contrast, the other options present positive outcomes associated with good rhetorical practice. Increased understanding among audiences, strengthened community dialogue, and enhanced persuasive impact are all results of effectively employing rhetorical strategies to engage and inform an audience. When these strategies are lacking, the opportunity for achieving these positive outcomes diminishes, leading to the likelihood of miscommunication.
