Yolanda was looking forward to giving her informative speech because she liked her topic--her hometown. however, when she gave the speech the audience seemed disinterested; she couldn't understand why she got such negative audience feedback. given this information about the situation, what was yolanda's mistake?

She was speaker-centered rather than audience-centered in her topic selection.                                                                    

Explanation:

Yolanda's mistake is that she was a speaker-centered rather than audience-centered in her topic selection.

The speaker-centered mode of communication is a model that is being used in public speaking and focuses completely on the various activities led by the speaker.

The model consists of five factors which includes:

1. The speaker.

2. The message.

3. The event taking place

4. The audience

5. The effect.

explanation:

allergens: overstimulate the nerve system

neurotics: attack nerve cells

mutagens: damage or otherwise alter dna sequence

generators: cause defects during growth and development  

carcinogens: cause unchecked cell growth

i hope you get the idea according to me these are the effects that happened.
