One difference between everyday conversation and public speaking is that public speaking prevents you from entering into an "ongoing conversation" (as described by Kenneth Burke).

When speaking to relatively uninformed listeners, it is best to state your thesis explicitly or they may not grasp your main idea

Indicate whether the statement is true or false

"Bob's totally gross" compared to " I don't like Bob because he uses vulgar language and ridicules his friends," demonstrates a difference in language

a. jargon. b. hyperbole. c. tone. d. precision.
