Completely depends what the question is. Basically, I'd go about mentioning the fundamentals for the crux of my essay - context/audience, purpose, ideas and values, techniques. In this way you are aiming to communicate to the essay marker that Speeches by Keating or Pearson or Bandler communicate values and ideas of human aspiration/personal beliefs through the use rhetorical techniques/devices (decorum, pathos, intertextuality, allusions, metaphors etc) to GAUGE the audience's attention so that they create an affinity WITH the orator's beliefs and the values they are addressing. Mention how the orator also influences their beliefs towards the audience through the use of context, so using past or present references to issues that may impact them and corroborate or add to the profundity of the speech.
Hope that helped
