What advice is given for using people as presentation aids in a speech?

Using people as presentation aids can enhance a speech, but it's essential to ensure they do not detract from the central message or the speaker's delivery. The correct answer emphasizes the importance of maintaining focus on the primary content of the speech. If a person introduced as an aid distracts the audience or takes attention away from the speaker, it undermines the effectiveness of the presentation. Thus, ensuring that these individuals complement the presentation rather than distract from it is crucial for maintaining engagement and clarity.

In contrast, having them stand in the front could lead to distractions if their presence draws attention away from the speaker. Encouraging them to interact with the audience may not always align with the intended speech structure, as it could divert focus from the main points being presented. Allowing them to take the lead in the speech could completely shift the focus away from the speaker, potentially confusing the audience and disrupting the flow of the presentation.
