The revision that most effectively uses a rhetorical question to engage the audience is:
"Today, we need to think about the legacy we want to leave for future club members. Do we want them to feel proud and included? If so, let’s make sure they do by implementing the changes suggested by our current members. It’s time to get your ballots and decide how you want to vote."
This version directly poses a rhetorical question that prompts the audience to reflect on their desires, thereby enhancing engagement.
