The student includes five supporting documents that are contemporary, published within three years of the IA submission, and clearly labeled. These documents provide relevant and in-depth insights into Netflix's pricing strategies and consumer retention, highlighting key information that directly relates to the IA. Additionally, the documents present a range of ideas and views on the topic, demonstrating the complexity of consumer reactions to pricing changes. However, the student does not assess the validity and reliability of the supporting documents, which is an area for improvement to strengthen the analysis.
