I really do need help im not joking about this question i swear i have to answer it for my history class
how one's gender or age affected his or her life in ancient Greece and Rome

I guess it would have to do with like the men having to do more manual labor and provide for the family and participate in politics while the women stayed home with the family.

interdependence is when all participating groups and individuals depend on each other. if you depend on one anothers goods, you end up trading in order to get the items you're looking for. (for ex: if i have food and you have water, we trade in order to depend on each other to live)
