One way in which the Industrial Revolution changed the nature of politics in America is through A. the birth of professional politicians. B. the creation of new parties. C. the push for direct democracy. D. the rise of labor unions.

Option D, the rise of labor unions, is the right answer.

Explanation:

The Industrial Revolution was a period of time in which various technological discoveries took place. The Industrial Revolution first began in Britain and then spread to other parts of the world such as America, Japan etc.

During this time, the production was primarily done using machines. However, to run such machines labor was required. Due to the "Agricultural Revolution," the food production was in surplus thus the rural population moved to the urban areas in search of work. These labor were available in a great number. As a result, the factory owners hired them for low wages.

The working condition in factories was severe and child labor was prevalent. Therefore, the labor unions emerged to protect the rights of labors. And this is how the labor unions changed the nature of politics in America.

D. the rise of labor unions

Explanation:

With more people working in factories, concerns arose over working and safety conditions. This led groups of workers to come together to demand better wages and safer working environments. Eventually, these groups became politically active, so the rise of the labor union meant politicians had to attract their members to win elections.
