A speech about Olympic swimmer Michael Phelps divided into his three most successful events would be best organized according to which pattern?

Organizing a speech about Olympic swimmer Michael Phelps into his three most successful events fits well within a topical pattern. This organizational structure allows the speaker to divide the content based on specific subjects, in this case, Phelps' achievements in distinct events. Each section can focus on one event, detailing aspects such as the challenges he faced, his training routines, records set, and the significance of each event in his overall career.

This method enhances clarity and coherence in the speech, as the audience can easily follow along with the structured presentation of information that highlights different facets of Phelps' achievements. By using a topical approach, the speaker can provide rich detail and engage the audience with vivid examples while maintaining a logical flow of information based on discrete themes.
