During the Middle Ages this group of people were not allowed to leave the land on which they lived and worked? is it slaves or serfs or peasants?​

I would guess slaves.

Explanation:

Slaves are different from servants, which could probably come and go. Servants were hired and paid to work for someone. Slaves were made to work and their "owners" would sometimes torture them if they didn't do something perfect.

do u have any answer choices?

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 !
