Approach this question as if you’re having an argument with yourself about what the author meant and why, in which neither side agrees or will budge. The stronger side will shine through. Do not panic!
Firstly, we are going to note all the similarities and the differences. Pick the two most important ones and shape the introduction around them. Connect terminologies to any concepts you identify in the text: this could be conventions, devices, or contexts. But we will go into them in more detail. Explain your interpretations; ask: why do I think this? Be selective in what you choose from the text and remember to use the PEEL structure (Point. Explain. Evidence. Link.)
