The student has effectively included five supporting documents in the work, ensuring they are contemporary and published within the last three years. Each document has been clearly labeled in a consistent manner. Additionally, the supporting documents are relevant, sufficiently in-depth, and provide a range of ideas and views regarding the topic. However, the student has not attached the documents to the work or highlighted relevant parts, which would have strengthened the presentation. Furthermore, the assessment of the validity and reliability of the supporting documents is lacking, as the student did not thoroughly consider these aspects.
