What happened after the battle of adrianople

In one of the most decisive battles in history, a large Roman army under Valens, the Roman emperor of the East, is defeated by the Visigoths at the Battle of Adrianople in present-day Turkey. Two-thirds of the Roman army, including Emperor Valens himself, were overrun and slaughtered by the mounted barbarians.

        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!
