The student provides a focused and detailed description of the main topic, effectively outlining the significance of understanding sugar content in fresh fruit juices and its health implications. However, the description of the research question lacks specificity regarding the means of investigation, which could be improved by including the method in the question. The background information is relevant and well-explained, covering the fermentation process and the role of Saccharomyces cerevisiae, while the biological concepts are articulated clearly for easy comprehension. Additionally, the student states both the null and alternative hypotheses, and the methodology is highly appropriate, ensuring that the investigation remains focused on the research question and includes valid steps to assure the relevance of results. Safety, ethical, and environmental concerns are thoroughly addressed, demonstrating the student's awareness of potential hazards and impacts associated with the experiment.
