Which civilization had the greatest impact on renaissance architecture? a) indus valley and chinese b) greek and roman c) harappan and indian d) mesopotamian and egyptian

I believe it was the greek and romans because of how deeply rooted art was in their culture.

Contributing factors  leading  to the harlem renaissance were the great migration of african americans to northern cities, which concentratedambitious  people in places where they could encourage each  other, and the first world war, which had created new industrial work opportunities for tens of thousands of people.
