This is the name given to the era of peace ushered in by the mongol conquest of eurasia in the 13th century.

Pax Mongolica

Explanation:

The Pax Mongolica is a term given to the period of Mongol domination in the 13th and 14th century. During this time, the Mongol Empire controlled much of Eurasia, which led to a relatively stable environment in terms of society, culture and economy. The term comes from the similar term Pax Romana. The Pax Mongolica ended when the Black Death began to spread, leading to the fragmentation of the empire.

biological/genetic factors means they were born or predisposed to have something. nothing can really change it, and you can't really do much to "fix" it. it isn't something learned

these are the biological factors:

adrian is relatively tall and he is on the basketball team

(adrian can't ever stop being tall or force himself to be tall. likely one or both of his parents are tall as well and they passed on the tall gene. he probably does basketball because he is tall)

the rest are environmental/cultural factors. these are things that are taught to us. for example, cynthia wasn't born saving pocket money, her family most likely taught her this (environmental factor)

hope this !
