Question

which two developments caused industrialization and the economy to grow during the gilded age?
a system of railroads and social change
new technology and workers unemployment benefits
new technology and a system of railroads
unemployment benefits and social change

Explanation:

During the Gilded Age, new technology (like the Bessemer process, electricity in factories) boosted production, and the railroad system expanded markets, connected resources, and facilitated trade, driving industrialization and economic growth. Social change was an effect, not a cause of growth; workers’ unemployment benefits didn’t exist then, and unemployment wouldn’t cause growth. So the correct pair is new technology and a system of railroads.

Answer:

new technology and a system of railroads (the third option, assuming the third box has this text)
