I seriously don't think it can be predicted, just assume it won't be peacemaking 'cos that was last years. And it probably won't be 2003's, whatever it was. Study them all for WW1, it's well basic anyway.
personally i think it might be on total war and mayb women because they havent focused on that in the past years.
but yeah, i agree it is hard to predict but its probably the easiest sectin out of them all anyway.
