The student's choice of the topic and research question is well-justified through personal relevance, as they express a strong interest in baking and its connection to yeast fermentation. However, the global relevance is lacking, as the student should have included statistics or discussions on the worldwide use of yeast and the potential implications of the investigation. On the positive side, the student demonstrates personal input and strong initiative in designing and conducting the study by including multiple pictures of experimental results, a self-made diagram of the experimental setup, and discussing the impact of a preliminary trial on the actual procedure.
