For context in general I actually just used textual references and nothing from real life.
I was doing identity and belonging so there was no shortage of real life examples, it's just when using these examples I felt I ran the risk of explaining something incorrectly or to a degree that failed to be sufficient, whereas the examiners have a background knowledge of whatever you choose to talk about when it comes to the text.
Instead of using real life examples I used two texts instead of one in my discussion.
When it comes to context I feel that there isn't really a set guideline in relation to the evidence you use in your piece, instead you have the freedom to move around and discuss the topic in depth with your own insights and interpretations flooding your work.
Instead of it being a text response, I tried to think philosophically about each prompt and respond with thoughts about the general society; I guess this in itself could be thought of as a crossover between a real life example and one that is within the text.
After all, a text is influenced and even revolving around experiences in the real world.
Unfortunately I can't refer specifically to your context in detail, but as each context is marked on the same scale the criteria you must fulfill will still be equal.
By writing in an essay form, I would refer to text only for the most part but you may run the risk of it beginning to sound like a text response. Because of this, I would encourage you to use examples, not quotes directly but scenes or other items of interest in the text. Refer to a real life scenario if one really applies, but I wouldn't spend an entirely long time discussing it. Instead, I found it helpful to dwell on the thoughts that I might have had about the context; although instead of making general statements extend on these by creating your own contention in response to your prompt.
Good luck!
