Answer:
The correct answer is B. The 1894 Pullman Strike crippled national rail service and triggered the arrest of union president Eugene V. Debs.
Explanation:
The Pulman strike was a nationwide conflict between unions and railway companies in 1894 in the United States. The conflict began in Pullman, Illinois, when on May 11, 1894, about 3,000 Pullman employees began a wild strike in response to lower wages and halted all movement west of Chicago. At the height of the events, in which the American Union of Railroads was the organizing force, the first national union in the United States led by Eugene Debbs, up to 250,000 people in 27 states participated in the fight against railroad companies on the part of the railroad.
President Cleveland sent federal troops to Chicago to stop the strike, which sparked a debate in his own office regarding compliance with the US Constitution.
The answer is B. Economic.
In sociology, the terms industrial, pastoral, and pre-industrial, are used to describe different types of societies that have existed throughout history. This categorization is based on the main economical activity of a society and there have been pre-industrial societies, and pastoral societies. However, the term economic society doesn't exist because every society, no matter its main economical activity, has had its own economic system.
Scatter plot diagrams are made by plotting the data plots gathered in an x-y diagram. Then, the data points are fitted to an equation. Correlations come from this made equations. They are deemed legitimate through the coefficient of correlation r-squared. If it is as high as around 0.99, then the equation is a good correlation for the behavior of the data.
