Expository paragraphs should be clear and be concise. This is because they should be brief, get to the point and explain the point, and then wrap up.
As far as I know, they do. the idea seems to be to inculcate the pupils (once the poor public, now the wealthy 'cos the facilities are good) in the ideas which the state has. former pupils have been given the strong notion to "serve the state" as a sort of "thank you" for their education.
Should they do this, or should they impartially teach ??? dunno.
