D Because of the Pullman strike

The Pullman Strike was a nationwide railroad strike in the United States that lasted from May 11 to July 20, 1894, and a turning point for US labor law. It pitted the American Railway Union (ARU) against the Pullman Company, the main railroads, and the federal government of the United States under President Grover Cleveland. The strike and boycott shut down much of the nation's freight and passenger traffic west of Detroit, Michigan. The conflict began in Pullman, Chicago, on May 11 when nearly 4,000 factory employees of the Pullman Company began a wildcat strike in response to recent reductions in wages. A total of 30 workers were murdered by railroad agents and their allies.

the process is called revolution because it was a process of great economic-social transformations that began in england in the xviii century.

the industrial mode of production spread throughout much of the northern hemisphere throughout the xix and early xx centuries.

the effect of this revolution was the distance between the countries, with respect to economic and political power.   after all, not all industrialized at the same time, remaining in the condition of suppliers of raw materials and agricultural products to the industrialized countries.

these differences mark to this day the nations of the world that are divided between developed and developing countries. one way to measure whether a country is advanced is to assess how industrialized it is.
