Question

Which of the following is a nonverbal strategy in public speaking?

a. pronouncing key words loudly for emphasis
b. varying the rate at which you speak
c. using gestures and facial expressions
d. using a series of words

Answer 1

C is the obvious answer because a involves talking and b shows the same thing. D shows how people use different words which is talking. Gestures and facial expressions use hand and face, not your voice. 

Answer 2

c. using gestures and facial expressions

Nonverbal means not speaking. The answer choice must be one that does not involve words or speaking. The only option that does not have spoken words is option c. When people use gestures and facial expressions, they are adding a nonverbal layer of communication to their speech. Options A, B and D are all verbal strategies.
