The student provided a focused and detailed description of the main topic, clearly stating the research question in the introduction and enhancing clarity through the Personal Engagement section. However, the description of the research question lacks specificity regarding the method of analysis, and the background information does not adequately detail the chosen countries or their HDI, which is crucial for context. Additionally, the biology explanation is insufficiently clear for full understanding, and the hypotheses section is incomplete, failing to articulate both the null and alternative hypotheses. While the methodology is appropriate and focused on answering the research question, it lacks sufficient detail on controlling variables and does not adequately address ethical and environmental concerns, which diminishes the overall robustness of the investigation.
