What were two reasons for the rapid spread of slavery in the American colonies? Africans migrated to the colonies to escape from starvation.
Colonists found that they could profitably grow cash crops with enslaved labor.
Indentured white laborers who arrived in New England were sold as enslaved people in the south.
Slavery was already common in the Caribbean when rice was introduced in South Carolina.
The Spanish sold the American Indians in their Caribbean colonies as enslaved people to the American colonies.

which time period is this? or is this story fictional, i'm going to need more info to answer this question

an earnest tone.

because portia wants to know why brutus has been acting strange lately.

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 !
