<span>persuade listeners to participate in an Earth Day event.
The principal's speech details the way students can participate by walking to school instead of using energy and driving. He gives details about the event and also the incentives to participate like berry smoothies. The other options are not valid because he does not speak about Earth Day's history or the threat of an energy crisis. He does mention the boundaries, but only to explain why there are drop zones for the event.</span><span>

Based on the given sentence above, the correct answer for this would be the third option. Basing on the point of view of the speaker, we can say that it is in the third person in which he/she means of Akiko. Since Akiko is only one, this is considered as singular. Hope this answer helps.
