What are social fact and social authority? Provide one example for each.

the course is Expert Witness in Forensic Science, and the questions are from chapter 9, Science and Social Science Evidence which I will upload.
No outside sources are allowed.
The questions are:
1. What are social fact and social authority? Provide one example for each.
2. Who were the two authors that argued for the categorization of evidentiary requirements for social science? Briefly explain.
3. What are adjudicative facts? Provide one example.

Thank you very much for your help.
