Which achievement played an important role in pre-columbian mesoamerican civilizations? (1) use of gunpowder (2) production of corn (3) domestication of horses (4) development of sugar plantations

on the whole, dickens has shown the french revolution and its this site might you. good at his job, and the subject matter he chose, 

        i'm fairly sure that the correct answers are 2 and 3.

        i used both my knowledge of world history and the process of elimination to obtain these answers. option 1 cannot be a possible selection because the mandate of heaven belongs to ancient chinese philosophical belief. option 4 sounds like it would benefit the region than detriment it. however, both 2 and 3 explain a potential reason for what could have contributed to the fall of the roman empire.

      hope this ! if i were you, i'd get a second opinion, because i haven't taken this course for a year. best of luck!
