What was the major innovative technique that allowed Henry Ford to produce an automobile that could be manufactured and sold at
a reasonable cost? He pioneered the use of aluminum frame designs. He used the assembly line production process. He developed an automobile that ran on less fuel. He invented the inflatable tire for the automobile.
The technical innovation of Henry Ford for the production was the assembly line. It is considered that it was a revolution in terms of productivity since it reduced production costs and made the masses have access to this type of product. This model was based on the division of labor. In this way, the production was segmented and each operator was in charge of a task in a repetitive manner. The result was to create products in large quantity and at low cost, this brought with it a wider market and higher productivity.
The major innovative technique that allowed Henry Ford to produce an automobile that could be manufactured and sold at a reasonable cost was the assembly line production process. From this new production system, called Fordism (term coined by A. Gramsci), serial production is developed. In this process each of the parts is added as the product progresses along the work station, until the final assembly is achieved. With this system it was necessary to have many workers using machines and developing repetitive tasks. So it was possible to control the productive times of the worker, now in the hands of the employer (determined by the speed of the assembly tape).
Plessy v. Ferguson ruled that "Separate but equal" public facilities were constitutional, thus permitting the practice of segregation under Jim Crow laws in the South and separate facilities for African Americans.
Therefore, the correct answer is C, that the decision allowed Southern states to legally segregate facilities and institutions.
