Why did the federal government become involved in the american railway union's strike against pullman? a. it was an unusually violent strike. b. it targeted only trains that had pullman cars on them. c. it was the first successful strike in some time. d. it involved interstate commerce and mail movement.

A). It was an unusually violent strike.

Explanation:

The federal government became involved in the American Railway Union's strike against Pullman company as it was an unusually violent strike that could not be overlooked as it affected the freight badly. The federal government carries the right to intervene in labor disputes or strikes especially when it adopts a violent form. The Pullman strike badly affected the nation's freight. Thus, the federal government interfered to end this protest in order to get the things back to normal by ordering the army to control the strikers and when they(strikers that were obstructing the trains) refused to violate the judicial order, they were imprisoned. Thus, option A is the correct answer.

best of luck!
