In a draft addressed to organizers of a civic forum, the writer's thesis is that public forums should use stronger moderation rules. The writer wants the claim sequence to protect open discussion by preventing domination. Major claims: I. Without clear time limits, a few confident speakers can dominate the meeting and discourage quieter participants. II. Moderation rules can set equal speaking time, require topic relevance, and invite written comments. III. A forum is most democratic when many residents have a genuine chance to be heard. IV. Stronger moderation would make the forum more open, not less, by distributing attention fairly. Which order most effectively advances the argument?
