There's ground to write an essay based upon that question, but I doubt they'd give such a narrow question in the HSC, seeing the majority go over 10-15 years, and that question covers 1943-45. It's an awkward question, but presumably it would be an idea of talking about the various impacts involved, economic, social, military and so-forth, discuss how 'Total War' was used as a means of maintaining support and the ability to fight, and so-on. (Incidentally, Goebbels was made 'Plenipotentary-General For Total War' on July 19th 1944, or thereabouts.)
Incidentally, would it be worth discussing the volksturm in a question of that nature?
