The student includes four supporting documents, which fall within the required range. All supporting documents were published within the past three years, aligning with the recency requirement. The documents are clearly labeled as “Supporting document 1,” “Supporting document 2,” etc., which aids in organization and reference. None of the supporting documents is a transcript of video or audio material. Each document provides insights into Louis Vuitton’s practices, ethical concerns, and consumer perceptions, which are relevant to the research question. The student highlights relevant sections within each supporting document that directly relate to the research question, helping to focus the analysis and draw clear connections between the supporting evidence and the IA's investigation. The supporting documents include both perspectives on Louis Vuitton's ethical claims and critiques from organizations like PETA, which provides a balanced view. However, the student should add a brief assessment of each document’s validity and reliability, possibly addressing aspects like the source’s credibility and any potential biases.
