What is "silence" in a presentational aid, and why is it important? Provide at least two examples of how a speaker might achieve "silence."

What will be an ideal response?

The best answers include:
1. the definition of "silence"
2. an explanation that "silence" helps avoid distraction and inattention. Using "silence" helps speakers to achieve better the goal of visual aids, that is to direct audience attention at specific moments to specific things. Outstanding answers will refer back to Chapter 11 to explain that "silence" can aid in overall delivery and audience comprehension of material, just as verbal pauses do.
3. examples of achieving silence, such as including blank slides in a PowerPoint or Prezi and removing transparencies or covering objects when not in use.
