Answer:
The author searches for school records and real documents that report facts and situations that can explain Georgetown's involvement with slavery and compare it with the involvement that other institutions had.
Step-by-step explanation:
The author shows how Georgetown started a research work through school documents and records that proved Georgetown's participation and involvement with slavery and mainly with the sale of slaves. These documents allowed the comparison between the Georgetown movement in relation to other institutions, in addition to allowing the elaboration of programs that benefit the entry of descendants of slaves in the university, as a way to repair this very degrading moment in American history.
