Which of the following is not a true presentational aid? After you identify it, explain in detail why it is not a true presentational aid

(A) In a speech about legalizing "Death with Dignity" laws, the speaker includes in her Prezi a map of the U.S. with the number of cases of terminal cancer in the past year listed on each state.
(B) In a speech about raising the "debt ceiling" in the U.S., the speaker includes a PowerPoint slide with many dollar signs ($), which wiggle from side to side and flash different colors.
(C) In a speech about dieting, the speaker holds up a pack of playing cards to explain the appropriate portion of meat in a typical meal.

What will be an ideal response?

The best answers will identify (B) as the correct answer before explaining that:
1. the content does not enhance the speaker's verbal content.
2. the movement, colors, and crowdedness of the slide can create audience distraction and inattention.
3. Outstanding answers will offer ways in which this slide can be made into a true visual aid, such as reducing the number of dancing dollar signs to one or two, flanking relevant information or a key point. This less-is-more approach can help the speaker increase audience retention to the key point by adding a visually stimulating element to the content.
