The student employs appropriate research methods and clearly explains the methodology, utilizing both primary sources and secondary literature to support their analysis. The essay adheres to academic conventions, with a clear structure and appropriate headings that facilitate understanding, though the integration of externally-sourced images could be improved for clarity.
