ALEVEL Edexcel History coursework

I'm doing the question about the significance of German imperial ambitions on the origins of the First World War. I'm confused on how to do one of my sections, 'Other Historians'. I'm not sure if everyone else has a different structure to mine, but this is the way we've been told to do ours: Introduction, 3 main body paras each on different historians, another body paragraph on 'Other Historians', conclusion.

I found categorising the paras into themes useful too, as in different factors that contributing to WWI for each para. I was really confused on the difference between 'main historians' and 'other historians', so thank you!
