Henri is writing a letter to the school newspaper about the problem of food waste in the cafeteria. He wants to convince students to help reduce the waste. Which concluding sentence uses an appropriate tone to convince his audience to help?

A persuasive conclusion should encourage readers to act without blaming or insulting them. “I challenge each one of you to be part of the solution” directly invites students to help reduce food waste in a respectful, motivating tone. The other choices sound accusatory, angry, or insulting, which may make readers less receptive.
