The student included three supporting documents that are contemporary, having been published in 2023, thus meeting the requirement for relevance. Each document is clearly labeled, allowing for easy identification, and they provide a range of ideas and views regarding Starbucks' green marketing strategies. Furthermore, the student effectively highlighted relevant parts of the documents in the assessment. However, the student does not provide an assessment of the validity and reliability of the supporting documents, which is a noted deficiency in the submission.
