1500 word essay and bibliography

Please do not use overly complex English in the essay. I would like it to be of 2:2 quality but in a way that is easy to understand.

Sentance structures were inaccurate etc so please be careful with this…
It must be of quality obviously (not ridiculously basic sounding).
