For Question 3 I've been taught to do at least 3 paragraphs on a contextual approach
1. Subject (obviously the same)
2. Audience/ Register (normally linked, could be diff or same depending on the texts we get)
3. Purpose/ Mode/ Genre (again normally linked and could be different)
Then a short line concluding the question (basically summarising your points)
My teacher has told me not to focus on the analysis on Q3 as the majority of it should've been completed in the Q1 and 2. This should be a mainly contextual focus question
Also, if you are stuck on a plan think of RTA acronym:
Represented
Technique
Analysis
