The nan song was the first dynasty to allocate a standing army at a port of trade for protection. what would be the reason for doing this?

to protect the borders of china from illegal entry of foreigners

to protect foreign traders from a citizenry who did not like any foreign influence on their country

to protect all concerned with the trade industry thus insuring its continuation

to protect the citizenry from foreign traders who were known to be brutal and barbarous

it is the code of hammurabi

if you could provide the poem below, i'd be happy to you!

explanation:

you didn't give us the poem, or the title of the poem. but it is essential for you to give us that, otherwise we can not detect when the poem has a tonal shift!

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 !
