Question

the violent union strikes in the 1890s helped reinforce the belief that labor union members were
a anarchists.
b capitalists.
c democrats.
d republicans.

Explanation:

In the 1890s, violent union strikes led the public to associate labor - union members with anarchists due to the radical and law - defying nature of such actions. Anarchists oppose established authority and seek to overthrow the existing social order, which the violent strikes seemed to represent in the public perception. Capitalists are the owners of the means of production, Democrats and Republicans are political parties in the US, and these do not align with the perception created by violent strikes.

Answer:

A. Anarchists
