What makes high school successful?
One paragraph

if you cherish the moments and if you do your work and make  friends that can make high school together

Explanation:

Couldn’t tell ya, I’m not in high school

Explanation:

But I assume if you have dedicated teachers that help you put in hard work to achieve your dreams or goals, that would make a successful highschool. When students learn and remember things that can actually be applied in life. When teachers hold students to high expectations, and make sure they get there. When teachers explain concepts and lesson to where it is understandable for every student. When the school has a positive environment. When teachers understand they are responsible for the students, and that is their job to help them succeed.

the answer is both an appeal to ethos and logos (if that's what your question options were)

sorry no one is gonna answer you if you keep repeating the same question over and over again.
