Kindly note that if a source was in the previous paper and not in this final it is because the student had listed it and did not use it in citation so I have removed it. In addition, some of the sources may seem to have different names because in the previous document I had either cited them wrongly or the student did cite them wrongly.
All in all, I cannot say this final paper is error proof as it is a big paper, but I have done my best to keep them to as minimal as I can
