Let me get this straight. You're asking me how I researched the research?
Nope, I'm asking how you've planned the research, what materials you've analized, who were your sources. I already explained how I did mine above, so I'd like to know what paths you took.
Unless, from what your question seems to imply, all you've done was read the research someone else put together, which, except if it involves a primary school project, doesn't qualify as research.
