What does the "Rule of Three" in public speaking recommend?

Why: The Rule of Three specifically recommends structuring key points into groups of three, since audiences find triads easier to remember than longer lists. Why the Other Options Are Excluded: •  The rule concerns grouping ideas, not restricting sentence length to three words. •  The rule concerns the structuring of content, not the overall length of the speech. •  The rule is about grouping distinct points into threes, not repeating one point three times. •  The Rule of Three concerns how key points are grouped for retention, not how many questions are posed to the audience. Industry Example: A speaker organising a talk around three memorable takeaways — start early, contribute regularly, review annually — is applying the Rule of Three.
