Final answer:
During wartime, a speaker can establish credibility most effectively by quoting respected military strategists, which associates the speaker with knowledgeable authorities and lends weight to the speaker's own assertions.
Step-by-step explanation:
To establish credibility in the eyes of an audience during wartime, a speaker would most likely quote respected military strategists. This approach directly associates the speaker with knowledgeable and reputable sources who have authority in the field. Leveraging the respect held for these figures can effectively enhance the speaker's own credibility and implicitly argues for the validity of the speaker's points. By showing familiarity with military strategy and its historical context, quoting esteemed strategists suggests that the speaker has a serious and informed perspective on the matter.
In contrast, using hyperboles and metaphors may engage the audience and provide vivid imagery or simplification of complex issues but does not inherently build credibility. It could, if overused or inappropriate, even undermine the speaker's reliability. Instead, by sharing personal experience related to war, the speaker strengthens their connection with the audience, adding emotional weight to the discussion.While targeting emotional concerns is a persuasive strategy that can appeal to sentiments such as patriotism, a careful use of rhetorical devices, including the aforementioned quoting of authorities, is crucial to enhance a speaker's perceived trustworthiness and expertise.
