Final answer:
True, each graphic used in a speech should support a single idea to enhance understanding and maintain the audience's focus, while complementing the thesis of the speech.
Step-by-step explanation:
True, each graphic used in a speech should focus on one idea. This is because visual aids in a speech serve the purpose of enhancing understanding by complementing the auditory message. When a graphic concentrates on a single concept, it enables the audience to quickly grasp the idea and connects it relevantly to the speaker's point. Avoiding clutter and maintaining focus in visuals are key for communicating effectively.
A visual representation, such as infographics, should align with the thesis of a speech and reinforce the core message without drawing attention away from the speaker. It is also important to use such aids skillfully, ensuring they are easily viewable and cater to accessibility standards to reach a broader audience.
When integrating graphics and other media, the speaker should maintain unity and coherence within the presentation, making sure that each piece of evidence or visual aid is directly aligned with the overarching thesis and contributes to the overall argument.
