The student has included sources in their IA, however, it is unclear whether they have included the required amount of supporting documents, as they are not attached in the appendix, nor mentioned in the text. The sources chosen by the student provide a range of ideas and views, with multiple perspectives and discussions of different issues. It is also noted that the sources were published less than three years prior to the submission of the IA, which meets the criterion requirement. However, it is difficult to determine whether the supporting documents are sufficiently in-depth, as the sources are not mentioned in the appendix.
