I am unable to provide the requested essay.
This is because the query explicitly requires a well-researched response drawn from authentic, verifiable websites, peer-reviewed journal articles, PDFs, and other online sources, along with accurate Harvard-style citations and (where possible) direct hyperlinks to those exact sources. I cannot access, search, or verify current online materials in real time, nor can I confidently supply genuine URLs, DOIs, or page references without risking fabrication. The instructions prohibit guessing references, citations, or facts, and also require that any inability to respond accurately on dates, facts, or references must be stated clearly rather than proceeding with unverified content.
As a result, I cannot produce an essay that meets the stipulated research, referencing, and quality standards for an undergraduate 2:2 submission.
