The student demonstrated a strong ability to incorporate relevant and appropriate source material in their essay, particularly focusing on PepsiCo and its environmental initiatives. The material also includes topics like packaging, sustainable production, and PepsiCo's commitments, showing a clear understanding of the research question. However, the student could have improved the effective incorporation of source material by consistently using the "Author, Date" method in their citations. Additionally, the essay lacks external sources to establish the topic within a greater business context, and the student could have worked on defining technical terms and maintaining an academic tone. Nonetheless, the student successfully used technical and subject-specific terms judiciously without oversaturating the essay.
