Explain the differences seen among the three major speech purposes, and provide concrete examples to illustrate your points

What will be an ideal response?

Public speeches are structured and presented for different reasons – to inform, to persuade, or to perform a function during a special occasion. These three types differ in several ways: 1) The informative speech creates understanding – clarifies, instructs, corrects misunderstandings, or demonstrates how something works. 2) The persuasive speech influences attitudes or behaviors – strengthens or changes audience beliefs, or inspires listeners to take some specific action. 3) The special occasion speech contains elements of both information and persuasion – introduces another speaker or a group of speakers, presents an award or tribute, secures the goodwill of listeners, or entertains the audience.
