Question

questions.

1. What is the use of audience in rehearsing public speaking?

2. Author mentioned “structure of the Group” in effective speech, what do you mean by that?

Answer 1

The audience provides feedback to the speaker.

I don't know to what author you're referring. But "structure of the group" to me means the interests of the group. A group of accountants has different interests than teenagers or teachers or parents.
