Henry8th people this is the structure I am using for my main body paragraphs:
Point (agreeing with the question)
Example (sources that both support, possibly a third source if it does, and suggest something that supports the questions statement),
Explain (this is combined with the example which pretty much just explains the point it makes,
Evaluation (questioning the author, the time it was written and maybe undermine sources with other sources),
Explain (this is just the area where I reach my judgement
That is for part a for part b I throw in own knowledge after the example to support it further, also during the example I cross-reference the sources. Do you reckon this will be good enough for a high grade? Also for part a I plan on discriminating between the sources and partly the same for part b, but it depends more on the source writers and whether there is some bias.
