Answer:
One helpful statistic we can use is the amount of enslaved people per county, in the year 1860, just a year before the American Civil War.
Explanation:
This statistic can be used as a proxy to determine the counties were cotton had the highest production, because cotton was a cash crop grown in large plantations that were worked by enslaved African Americans.
Several counties had 80% or more slaves as percentage of the total population, meaning that they were overwhelmingly black. The majority of these counties were located in the Mississippi Delta, in the state of the same name, in the Black Belt of Alabama and Georgia, and in southern South Carolina.
Johann Gutenberg’s invention of the printing press around 1448 had a significant impact on the spread of ideas in Europe and beyond. Printing technology traveled quickly across Europe and, at a time of great religious change, played a key role in the success of the Protestant Reformation. Reformation leader Martin Luther could only preach to a small number of people, but the printed word could spread his message to thousands more
The printing press drastically cut the cost of producing books and other printed materials. Prior to Gutenberg’s invention, the only way of making multiple copies of a book was to copy the text by hand, an laborious and intensely time-consuming occupation usually performed by monks. The materials involved were also costly: Monks wrote on treated skins, known as vellum, and a single copy of the Bible could require 300 sheepskins or 170 calfskins. Printing onto paper made copying cheaper and faster.

One negative consequence was that the British would take raw materials from India at a very low cost. They would then sell them for much higher.
This took away a lot of business from the Indians.
