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.

since most of current immigration into the u.s., both legal and illegal, is coming from latin america. it would be very difficult to imagine or rationalize a country my fellow citizens are trying desperately to flee into, would pose a threat to my prosperity or freedom. since the u.s. has a long history of intervention, but no record of permanent occupation, i would not feel oppression is the main objective.  

the largest free trade nation, along with the largest gdp in the world wanting to expand it's economic policy on us, and including us, could only be positive. the u.s. government has no interest in, or way of simply forcing american culture on us. and has no track record of it. other nations that adopted american social culture, or "americanization" did so voluntarily, mainly through the choice of allowing american businesses and u.s. citizens to come into their nations, as free operatives.

barrio is a spanish word meaning neighborhood. in spain, several latin american countries and the philippines, the term is also used officially to denote a division of a municipality while a ghetto is a part of a city in which members of a minority group live, typically as a result of social, legal, or economic pressure. the term may have originally been used in venice to describe the part of the city to which jews were restricted and segregated.
