Question

which workers benefited most from the shift to assembly line production during the second industrial revolution? members of large organized labor unions; skilled workers with years of specialized training; apprentice workers who had completed an apprenticeship; unskilled immigrant workers willing to work for low wages

Explanation:

Assembly - line production during the Second Industrial Revolution required less - skilled labor. Unskilled immigrant workers willing to work for low wages could fill these jobs more easily compared to highly - skilled workers. Organized labor unions faced challenges as employers could more easily replace workers with unskilled immigrants. Skilled workers with specialized training or apprenticeships saw their value diminished as tasks became more standardized and less complex on the assembly line.

Answer:

Unskilled immigrant workers willing to work for low wages
