The migration to urban centers that is evident in the source is most likely a result of which early modern process?

A) improved agricultural productivity

Explanation:

With the flourishment of agriculture, the supplies of food started to multiply. This meant that more and more people could survive and that the less of them needed to survive off their own farmland. If more food was made, the ones making it could feed their families and sell the goods to the others.

Guided by these ideas, many people started moving to urban centers. The food was not a problem, and people could live off the supplies that they buy, which were made by someone else, rather than to make only their own food.

Therefore, fewer people needed to work in agriculture, so the arts, industry, science, politics, and culture could start getting developed in urban centers.
