Read the scenario. Haruna's group is rehearsing to deliver a presentation to the school's principal about why robotics should be offered as an elective class. Which would be the most appropriate tone for the group members to use while giving their presentation?

The group is trying to persuade the principal to offer robotics as an elective, so its members should sound sincere and serious about the reasons they give. An earnest tone communicates genuine conviction without seeming forceful. A demanding tone could sound disrespectful, while instructive or dramatic tones do not fit the purpose as well.
