Question

ethan is giving a highly technical presentation on biomedical engineering involving several working models, computerize graphs, and video clips to a small group of doctors, scientists, and engineers. which two characteristics of public speaking should he be most concerned with during his preparation?
a. delivery and audience
b. noise and delivery
c. channel and message
d. none of the above.

Explanation:

Ethan's presentation is technical, for a specialized expert audience, and uses complex tools (models, graphs, videos). The channel refers to the tools/mediums used to share the content, which need to be tailored to work smoothly for the technical material. The message must be precise, technically accurate, and aligned with the audience's expert knowledge. Delivery is less critical here than ensuring the right medium (channel) and accurate technical content (message), and noise is not a key preparation concern for this small expert group.

Answer:

c. channel and message
