At what age did the slave begin to work full time in the fields? fifteen nine twelve sixteen

The answer is 16

Explanation:

It varied according to plantation, person and occupation. Almost all slaves were working full time by the age of 16. Before the age of 16, they worked accordance with their maturity.

an economic reason that the south needed a reconstruction plan is that plantations, factories, and other businesses were destroyed during the war.

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 !
