Which of the following refers to main points of a speech outline being worded in a similar structural pattern?

The term that describes main points of a speech outline being worded in a similar structural pattern is "parallel." In public speaking and speech writing, employing parallel structure is crucial because it enhances clarity and memorability for the audience. When main points are presented in a consistent format, it helps listeners follow the speaker's arguments more easily and makes the speech feel more cohesive.

For instance, if the main points are structured as phrases starting with verbs or as questions, maintaining that pattern throughout the outline reinforces the message and engages the audience more effectively. This technique can also create a rhythm that adds to the impact of the speech, allowing for smoother transitions between points and contributing to overall persuasive effectiveness.
