If a person is delivering a speech with evidence, which of the following factors will most likely make the speech more effective?

The effectiveness of a speech often hinges on how well the speaker engages with the audience through naturalness and a conversational quality. When a speaker conveys their message in a natural manner, it enhances the connection with the audience, making the content more relatable and digestible. A conversational quality allows the audience to feel at ease, fostering a welcoming environment where they are more receptive to the ideas being presented.

Additionally, a natural delivery can help the speaker emphasize key points with appropriate pacing and tone, making it easier for the audience to follow along and understand the evidence being used. This approach often leads to a more impactful delivery, as it aligns with how people typically communicate in everyday interactions, thus enhancing retention and engagement during the speech.

Other factors may contribute to the effectiveness of a speech, but the combination of naturalness and conversational quality is particularly powerful in creating a meaningful interaction between the speaker and the audience.
