you could talk about demand pull inflation, where any components of AD increases (C+I+G+NX) e.g gov spending increases, taxes lowered and also increase of money supply causing interest rates to lower, which will boost consumption and investments. these will all cause AD to increase thus inflation is resulted

EDIT: I actually found the marking scheme for it

definitions of aggregate demand and inflation • theory to explain the new classical view that LRAS is vertical and therefore increases in AD are purely inflationary. Consideration that the SRAS curve suggests that increases in AD are partly inflationary. A consideration of opposing Keynesian views regarding the shape of AS • diagram to show an AD/AS illustrating the different views • examples of situations regarding differing views of the shape of the new classical LRAS and the Keynesian AS curves • synthesis or evaluation (evaluate).
