Answer:
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, <u>option A</u> is the correct answer.

<h3>What is Social Behavior?</h3>
Social behavior is defined as interactions among individuals, normally within the same species, that are usually beneficial to one or more of the individuals. It is believed that social behavior evolved because it was beneficial to those who engaged in it, which means that these individuals were more likely to survive and reproduce.
Social behavior serves many purposes and is exhibited by an extraordinary wide variety of animals, including invertebrates, fish, birds, and mammals. Thus, social behavior is not only displayed by animals possessing well-developed brains and nervous systems.
Therefore, we can conclude that this study was a demonstration of<u> </u><u>the</u><u> automaticity</u><u> of </u><u>social behavior.</u>
