I believe that geography affected human migration by pushing them away from the less fertile and less inhabitable locations and pushed them towards places with a sturdy water supply, rich soil, or another factor that allowed people t have a higher standard of living. Humans adapted to certain situations if they were unable to travel or didn't want to move by using whatever possible resources were around them to make their situation better and easier to live purely by themselves.
Well I can tell you that L'Ouverture lead the slave revolt in Haiti because I literally just took a quiz on that about 3 minutes ago. I really don't know about jean jacques. sorry
