This question doesn't sound like it has a right or wrong answer (the school just wants your opinion), so if I were you, just pick a random problem you have with the school and write about how the school could solve it.
If you want to pick one of the "problems" (it is a little confusing) listed above, then just choose "rumors" and write about how the school could help when a bad rumor starts going around the school.
Just write whatever you feel is correct, there's no wrong answer on this.
