In order to provide a piece of evidence to compare the level of the Incas’ and Maya culture’s investments in public works projects, you can mention the following:
As regards Incas' architecture: Qollqa were stone houses situated on hillsides. They had drainage canals in order to keep the interior dry. Another example can be Machu Picchu that was a settlement like a fortress (located in the High Andes of Perú)
As regards Mayas' architecture: its region consisted of the northern lowlands, their pyramids relied on intricately carved stone. They built temples like 'The Temple of the Cross at Palenque. Usually, their structures were covered with stucco to smooth imperfections. Besides, their structures were aligned so as to have an astronomical observation.
The north and the south differed in a couple of ways in the mid 1800's, economically and socially which contributed to a rise of regional populations with contrasting values, ideologies and visions for the future. The differences includes; vast industry and immigration in the north, established agriculture in the south and slave trade carried out in the south.
This is true.
The process described in the statement is known as urbanization. Urbanization discusses how individuals moved from the countryside to the cities for economic opportunities. These economic opportunities were made possible by the inventions developed during the Industrial Revolution. Inventions like interchangeable parts allowed for companies to mass produce goods for the American public.
