Speech outlines that adhere to the principle of subordination will indicate sub-points with which of the following?

The principle of subordination in speech outlines organizes information in a clear hierarchical structure, where main points are emphasized while allowing for detailed supporting information to be included in an organized manner. Sub-points are typically indicated with lower-case letters, which follow the main ideas denoted by capital letters or numbers.

In this context, the correct approach to subordination is demonstrated through the use of lower-case letters for sub-points. This system ensures that the audience can easily discern the relationship between overarching topics and their supporting details, enhancing the clarity and effectiveness of the speech. Utilizing a structure in which capital letters designate main sections, followed by numbers or letters for sub-points, allows for a logical progression of ideas that is vital in public speaking.

Therefore, lower-case letters are the proper indication of subordinate points, facilitating a well-organized and coherent outline that audiences can follow easily.
