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 uses the rhetorical question "Do we want them to feel proud and included?" to directly engage the audience, prompting them to reflect on their own desires for the future of the club. It sets up a clear connection between their feelings and the actions they are encouraged to take, thus increasing involvement and emphasis on collective responsibility.
