What should Marcus keep in mind for his introductory speech for the guest speaker?

For an introductory speech, it's crucial for Marcus to effectively introduce both the topic and the speaker in a way that is clear, concise, and accurate. This approach ensures that the audience understands the context and significance of what they are about to hear. Providing this information builds anticipation and sets the stage for the speaker’s main content.

An effective introduction provides essential background, highlights relevant credentials of the speaker, and articulates why the audience should be interested in the topic, thus enhancing the overall experience. Balancing these elements allows the introduction to establish credibility, connect with the audience, and create a smooth transition into the speaker's presentation.
