Final answer:
Isaac should use examples as the best supporting material to vividly illustrate the effects of sun damage, offering real-life scenarios that can resonate with the audience. Incorporation of visuals and personal anecdotes will enhance the emotional impact of the presentation.
Step-by-step explanation:
To provide a vivid, concrete, and personal impact for the audience about the effects of sun damage, Isaac could use examples as the best supporting material tool. Examples are powerful because they provide real-life, relatable scenarios that can help the audience visualize and understand the potential harm of sun damage. While statistics offer quantitative evidence and are an appeal to logic, personal or descriptive examples are likely to create a more emotional and direct connection with the audience. Furthermore, embedding these examples with visuals and media, such as photographs of sun damage or anecdotes from individuals affected by it, can enhance the presentation and make a lasting impact. This combination of evidence is consistent with the strategy that Desmond employs in their argumentation, incorporating both anecdotal and statistical evidence for reinforcement.
