Here is his reply:
"There is no rule here. I don't think it is likely that you will be asked if a political idea is more concerned with society than economy (or say, human nature or state). The ideas questions are always extent of agreement/disagreement. For plans we can always start with core concepts list and/or the four key areas (economy, states, human nature and society)"
very relieved to hear we probably wont be asked that i'd be so stuck
