The correct answer to this open question is the following.
Here, there is no question at all, only a statement.
We assume that the question that is missing is something like "Could students express some critic the school in the school newspaper?
So if that is the case, then the above statement is correct. Yes, students should criticize the school in the newspaper, but they have to learn to do it with the utmost respect, never offending, always trying to sign what could be improved, and suggesting the best way to do it.
Another important point is that students accept that they play a role in improving things if they commit themselves to it. Sometimes, students are part of the problem, but they can also be part of the solution.
