Logos- "Prom usually makes students happy, and recent evidence has shown that when students are more happy they tend to focus more, which brings grades up and ultimately helps the school's reputation."
Ethos- "Many professionals recommend having a prom so that the students' minds can relax and to give them a small break so that they come back with more focus, drive and motivation."
Pathos- "Prom gives us students a break from all of the homework and studying and misery, and we would really appreciate it if you gave us just those hours of freedom before we submerge ourselves in our books once more."
I hope any of these work for you!
