"Highly popular"
?
very questionable (unless sarcasm), most schools stay away from it, due its vagueness, and the sophisticated level of thinking required to score well in it.
I'm studying Island for it.
You really need a fluid approach to answering this context area, and be able to draw upon ideas and examples relevant to landscapes of a more complex level than just the physical and literal ones - i.e., branching into the emotional, traditional, family, memory and imaginative landscapes etc. that encapsulate the human mind. It is quite a hard context area due to its vagueness, even harder than whose reality which is a bit more tangible. I would say be very broad in approaching a prompt and look to expand upon ideas that can be headlined under various "landscapes," and then explore ideas specifically linked to the text you are studying, making sure you explore at least one idea thoroughly - you don't have to make 3 or 4 ideas as some teachers say. It's essentially all about the interactions between humanity and the different
'landscapes" that encapsulate and govern it, and how well you can explore these ideas either in expository, narrative or one other type of writing which i forget, or a combination of any of the three.
Another tip - never take the prompt literally or as a narrow idea, and don't be afraid to counter the suggestion of the prompt, it is simply a prompt (not a question with a right or wrong answer). Hope this helps, sorry if it is a bit vague.
