To what extent was the popularity of the Nazi Party the main reason for Hitler's appointment as Chancellor in January 1933?

Here I am imagining a student has found difficulty both in how to structure their answer to an exam question such as this, and is also struggling with understanding the content of the question. Prior to our session I would also ask which exam board they are sitting so I can look at other past paper examples, the content they are required to know and also the criteria the examiner will be using. This information will help in tailoring the lesson to the student and the specific exam they will be sitting. Here is my answer if the student asks me to run through this question with them: 

The key to a strong essay lies in the structure of your argument. A strong introduction where you outline your argument and how you will 'attack' the question. A main body where you develop on the factors that aided Hitler in becoming Chancellor, all the while using these points to support your argument. And, lastly, a conclusion where you essentially summarise your findings and argument.

So, to begin with, what factors can you identify that aided Hitler in being appointed Chancellor in 1933? (would use the whiteboard here for a visual representation- FOR/AGAINST columns). That's correct- popularity amongst the elites, some of the populace, the economic crisis, the weaknesses of the Weimar constituion and Hitler's personal popularity. So with these factors you can now begin to structure your argument. To answer the question outright, what do you believe is the main reason for Hitler becoming Chancellor in 1933? 

Right, we shall now structure the essay around your argument. (I would now go through the factors the tutoree and I have identified, outlining on the whiteboard which factors you would discuss where in your essay structure. As we did this, I would ask whether the tutoree felt confident with the material. If they didn't, as we structured the essay together I would explain the factors with them). Consequently, on the whiteboard the tutee would have an essay outline, and we will have discussed the material throughout the session. In essence, we will have discussed both the structure and content of the essay question, revising any aspects that the tutee feels not so confident on.
