The student's choice of the topic and research question is well-justified through its global or personal relevance, as they provide a very good explanation of their choice of the topic and quote personal interest in the role of metal ions in biological systems and antioxidants, as well as the biological role of the catalase enzyme. Additionally, the student showed personal input and strong initiative in designing and conducting the study, as evidenced by their description of the conclusions made from the results of the preliminary experiment and the photos from their experimental setup, demonstrating personal input in conducting the study.
