A very brief statement that focuses audience attention on a key idea is referred to as which of the following?

A very brief statement that focuses the audience's attention on a key idea is known as a signpost. Signposts are important in guiding the audience through the structure of a speech and helping them understand where the speaker is going. They serve to highlight important points or transitions in the presentation. By providing these cues, signposts enhance clarity and comprehension, making it easier for the audience to follow along and retain the key ideas being communicated.

In contrast, transitions typically connect one idea to another within the speech, while internal previews and internal summaries are more comprehensive tools used to preview or summarize content within the speech itself, rather than drawing immediate attention to a singular important idea.
