Explanation:

Pax Mongolica means he Mongol Peace,s the name historians have given to the time from the 13th to the 14th century when most of Eurasia was under Mongolian rule. Eurasia was unified under the Mongolian Empire and many towns and cities left with no reason to go on war with each other, so the Mongols enforced a policy of free trade. They also built the roads required to conduct this trade and then used their forces to defend the roads from bandits. Such advances have sought to create a range of innovations and inventions of global significance, such as shipbuilding methods, printing presses, the compass, and a worldwide postal system.

        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!
