I've looked at a lot of past hsc exam questions for this and there are quite a few possibilities such as
How does one religions sacred text convey world peace?
How does one religions sacred text convey inner peace?
how does the principal teachings of one religious tradition help adherents achieve inner peace?
how does the principal teachings of one religious tradition help adherents achieve world peace?
And sometimes they ask for two different religions.

I'm just really stuck on how to prepare for this essay.
