The document compares and contrasts two presentation videos. The first video addresses childhood obesity and is not presented to a live audience but aims to educate parents. The second video is a TED talk presented live that discusses needed changes in the design industry. Both videos follow the rhetorical triangle framework of having a speaker, audience, and topic. While both are effective, the author argues that the live TED talk is more engaging as the presenter directly interacts with and solicits ideas from the audience.
