Final answer:
Aurelia is considering the audience's demographics when she takes into account their age, which is important for tailoring the presentation to ensure it is persuasive and culturally sensitive.
Step-by-step explanation:
When Aurelia considers the age of her audience, she is studying the audience's demographics. This includes the statistical data related to different population categories such as age, gender, education, and cultural backgrounds. The age of an audience can greatly affect how persuasive a message is, as younger adults may be more persuadable than older ones. Therefore, recognizing the characteristics of an audience, including their age, helps in tailoring the vocabulary, level of detail, and cultural sensitivity of the presentation. It's also important to consider whether there might be any secondary audiences and how much the audience already knows about the subject to accordingly shape the message and presentation for maximum effectiveness.
