Explanation:
Presentation can be defined as an act of talking or speaking formally to an audience in order to explain an idea, piece of work, project, and product with the aid of multimedia resources or samples.
Basically, any speaker who wish to create an effective presentation should endeavor to interact frequently with the audience by holding a conversation.
Ethos can be defined as the use of authority to significantly persuade or crave the indulgence of the audience to believe in a particular character. Thus, ethos simply means an appeal to ethics.
