• B. Involved only agriculture.
• C. Centered on steam power and textile machines.
• D. Was primarily a political movement.

Answer: (A)

The Second Industrial Revolution is defined by a shift to new industries and power sources that dramatically boosted production and reshaped society. It features the rise of steel, chemical, electrical, and oil industries, enabling mass production and the creation of more durable goods. Electricity becomes a central power source for factories and cities, transforming how and where work happens. Advances in chemistry, petroleum, and steel, along with innovations like the internal combustion engine, fuel new industries and transportation networks. Assembly-line methods and standardized production expand output, lower costs, and promote widespread employment, fueling urban growth and the emergence of a mass consumer culture, including cinema and radio. This era contrasts with the earlier focus on steam power and textiles and is not about agriculture or political movements.
