Final answer:
An agent must consider the medium and visual style when talking about marketing materials.
Step-by-step explanation:
When talking about marketing materials, an agent must consider the medium they will use to communicate. They need to decide whether to prepare a traditional written document or use another medium like a slide deck or video presentation. They also need to determine if visuals and other media should be included along with text, such as figures, charts, graphs, photographs, audio, or video. Additionally, the agent should keep a consistent visual style, provide space and time for the audience to engage with the materials, and consider accessibility for individuals with disabilities.
