Answer:
To detect compliance with regulatory requirements, including those relating to protecting research subjects.
Step-by-step explanation:
Oversight bodies are responsible for overseeing an area, such as IACUC, which oversees all animal research in the US. These bodies assess whether the activities of the area to which they are assigned are in compliance with the legislation and guidelines for that area. Based on this, we can state that the purpose of supervisory bodies is to detect compliance with regulatory requirements, including those related to the protection of research subjects.
