The student effectively incorporates relevant and appropriate source material in their essay, with the exception of Wu et al.'s reference, which needs to be included before the final submission. The majority of the source material comes from accredited scientific sources, and the student demonstrates their knowledge and understanding of the topic by explaining technical or subject-specific terms. The essay maintains an academic and analytical tone and style, with technical terms used only when necessary and not being oversaturated. However, the appropriate and consistent use of symbols, relevant equations, numbers of significant digits, and SI units throughout the essay needs improvement, as suggested by the examiner.
