QUESTION $11$

A central idea is a complete declarative sentence that:

is included in the planning outline, tells the audience what should be memorized from the speech, and is often stated word for word near the end of the conclusion.

is included in the planning outline, tells the residual message, and can be compared to the thesis statement in a written composition.

is the residual message but shouldrnot be included in the speech because the speaker should ask enough questions in the introduction that the listeners infer the central idea.

keeps the audience centered and balanced so they can recognize the speaker is an expert or an authority of the subject matter.
