Final answer:
To persuade the principal about the prom, use ethos to show credibility, pathos to appeal to emotions, and logos with data on benefits. For convincing parents to get a rabbit, demonstrate ethos with your research on pet care, use pathos to express emotional benefits, and logos to present the practical advantages.
Step-by-step explanation:
In order to persuade the principal to reconsider the cancellation of the prom, you could employ ethos, pathos, and logos. An appeal to ethos might involve showcasing your involvement in the school community and hence, authority on student events. Demonstrating how the prom benefits students' social development and school spirit might persuade the principal on an emotional level, using pathos. An appeal to logos could involve presenting data on how past proms have positively impacted school morale or citing surveys that indicate how much students value the event.
When convincing your parents to buy a pet rabbit, use pathos by discussing the emotional bond and joy a pet can bring into the home. You could also employ ethos, by showing that you've done your research on rabbit care, making you a credible source on pet ownership responsibilities. Finally, use logos by presenting the practical benefits, such as rabbits being relatively low-maintenance pets compared to dogs or cats and detailing the cost of their upkeep to prove affordability.
