I'd agree with Dupin - the context of the play might be important, it depends on which "AO"s [Assessment Objectives] are double-weighted... I'm not entirely sure if this applies to all modules and texts, but IIRC:
AO5 - The Historical context of the play; you should discuss how it is/was relevant to society at the time, and how it might apply to politics of today.
AO1 - Knowledge and understanding of the play/text; you'll need to use quotes from the piece and stuff...lol.
AO2 - Explanation/Arguing; you'll need to give a good argument and use clear and concise points to back it up.
AO3 - Your interpretation; give your own thoughts on the piece.
AO4 - Conclusion/evaluation; self-explanatory.
So if none of these are double-weighted, it's best to make sure you checklist all of them.
