There was a question that was completley about totalitarianism a couple of years back, it may have been 2002 but im not sure. I was pretty sure that it wouldnt be coming up again this time because of that.
I did Option A too - the negative consensous of Weimar Government, the continuing role of elites and military who were inextricably linked to politics since the time of unification - evidenced in Ebert Groener pact, Hitler as an oppurtunist, assisted by the negative consensous. The too-democratic constitution - Article 48- and coaliton Governments. However, the appeal of Hitler is testament to how his movements in ideaology 'Blut', 'Volk' and 'Furherprinzip' resounded with the nationalistic German public. Also, in 1933 Unemployment was at 6,000,000 but as Hitler revised the Treaty Of Versailles and began to rearm it hit 200,000. AJP Taylor also stated that 'The Depression put the wind in Hitler's sails'.
I thought it was a good question, thats a skeleton of my answer. Stalingrad was a bit offputting.
