The student's essay on environmental systems and society clearly establishes the context of the research question, demonstrating a strong understanding of the topic. The essay also effectively connects the study to the subject's theoretical body of knowledge, showcasing the student's comprehension of the subject. Additionally, the student ensures that the majority of the source material comes from accredited and scientific sources, and uses subject-specific terms correctly without saturating the essay with unnecessary jargon. The work maintains a consistent and academic style of writing, and effectively utilizes Environmental Systems and Societies terminology as per the subject Guide. However, the criterion regarding a clear and logical investigation based on raw data was not relevant to the essay's comparative study approach.
