The diagram that best describes the effects of the labor movement on late 19th-century American society is:
1. Strikes disrupted industries.
2. States broke strikes with militias.
3. Public opinion turned against unions.
4. The Knights of Labor grew more powerful.
During this time, labor movements and strikes were common as workers fought for better working conditions, fair wages, and improved rights. The response shows how strikes impacted industries, the government's response to strikes, the changing public perception of unions, and the rise of labor organizations like the Knights of Labor. These factors illustrate the complex dynamics of the labor movement during the late 19th century in America.
