Final answer:
Both session notes and video recordings are examples of permanent products a supervisor might review, making the correct answer C. both a and b. These forms of documentation create a lasting record of professional activities and can be reviewed for accountability, training, or research purposes.
Step-by-step explanation:
One example of a permanent product a supervisor might review is either session notes or a video recording, which means the correct answer is C. both a and b. Session notes (a) are written records of what transpired during a session, including observer comments, data collected, or interventions applied. They provide a paper trail for future reference and accountability. A video recording (b), on the other hand, offers a visual and audio account of the session, which can be a powerful tool for review and training purposes. Both are considered permanent products as they create a lasting record of professional activities.
In the context of research and sourcing, a primary source provides direct or firsthand evidence about an event or topic. Examples include a diary entry from a person who lived in the period under discussion or an official transcript, such as one from meetings between Department of State negotiators and Russian trade negotiators. Archival research also utilizes permanent products, where researchers may examine records that are archived either as hardcopy or electronically.
