Question

which was a major achievement of both the knights of labor and the american federation of labor during the late 1800s and early 1900s?

an end to labor strikes across the country

the expansion of the labor force to include immigrants

the reduction of the workday from ten to eight hours

the hiring of skilled labor in factories

Explanation:

1. Analyze Option A: Labor strikes continued during this period, so "an end to labor strikes" is incorrect.
2. Analyze Option B: The Knights of Labor initially excluded immigrants, and the AFL focused on skilled workers (many of whom were native - born), so this is not a major achievement of both.
3. Analyze Option C: Both the Knights of Labor and the American Federation of Labor (AFL) advocated for and achieved the reduction of the workday from ten to eight hours. The Knights of Labor pushed for this, and the AFL also supported the eight - hour workday movement.
4. Analyze Option D: The hiring of skilled labor in factories was more of a trend in industry and not a major achievement specific to these two labor organizations.

Answer:

C. the reduction of the workday from ten to eight hours
