The student includes four supporting documents, which is within the required range of three to five documents. The documents are contemporary, published within the last three years. However, the student has labeled all the supporting documents under one title in one table instead of labeling each document clearly. There is no transcript, audio, or video material used as a supporting document, which is not relevant in this case. The student has chosen relevant and sufficiently in-depth documents that provide a range of ideas and perspectives on the topic. However, it is advised that the student attaches important parts of the documents in an appendix and highlights them. The student also acknowledges limitations such as bias and staging of information by Tesla, demonstrating an assessment of the validity and reliability of the supporting documents.
