The student has successfully included five supporting documents in the work, all of which are contemporary and published within the last three years. Each document is clearly labeled, and relevant and sufficiently in-depth, providing a range of ideas and views regarding the topic. Additionally, the student has highlighted the parts of each supporting document that relate directly to their IA. However, the student did not include an assessment of the validity and reliability of the supporting documents, which could have added depth to the investigation.
