Which of the following is a commonly used tool for organizing the content of a speech?

An outline is indeed a commonly used tool for organizing the content of a speech. It serves as a structured framework that helps speakers arrange their main ideas, supporting details, and transitions in a logical and coherent manner. By using an outline, a speaker can ensure that their speech flows smoothly and that each point is clearly articulated. This organization not only aids the speaker in delivering their message effectively but also helps the audience to follow along and understand the main points being presented.

Outlines typically include a hierarchy of ideas, starting with the central theme, followed by major points, and then sub-points or supporting details related to each major point. This systematic approach facilitates preparation and practice, enabling the speaker to remain on track and cover all necessary content within the allotted time.

In contrast, the other options—footnotes, glossary, and appendix—serve different purposes. Footnotes provide additional information or citations for sources used in a speech, a glossary offers definitions of terms used, and an appendix contains supplementary material that, while useful, is not central to the main content of the speech. These elements are supportive rather than foundational to the organization of the main speech content.
