Did your teacher say what part of it you stuffed up? He/she would have some idea of what you could improve, not just 'the whole thing'....
The question is: "Compare the ways two scenes could be presented and the way those representations would value audiences"
This is how I'd approach this question.. which may or may not be helpful
Split/circle/highlight/underline the words 'compare', 'two scenes', 'presented', and 'value audiences...' (is that 'be of value to audiences? or is that verbatim?)
okay, so you're comparing, which means (well pretty obviously
make comparisons between these two scenes. Compare script, character, set, costume. 'Whilst (scene 1) does this, (scene 2) does that, blah blah.
The 'value' part i'm interpreting as family values, generational values, political, power, any of those themes that run throughout Lear. How are the values reflected to the audience?
My dodgy example really sucked so I deleted it.... but if I think of a better one I'll post it
Generally if a question says TWO scenes stick to TWO scenes; try to choose two scenes which are related (well, the ones with Lear and his kids are the ones I can think of, or Edmund and his father), and don't just describe the scenes, compare production features. It doesn't hurt to throw in references to versions you've watched either..
If that didn't help, it means I've totally forgotten what King Lear is about.
