What was the result of the migration of large numbers of people into Latin America's cities?

A) Recent improvements in industrialization as the labor pool has grown.
B) A clearer demarcation between those who remained in the isolated countryside and those who moved to the cities.
C) A scarcity of farm workers that makes it difficult to raise enough food to feed everyone, including those who have migrated to urban areas.
