electric lights made it possible for factories to run after dark

question 2
1 pts
which of the following had the greatest impact on transportation during the \second\ industrial revolution?
the steam engine
the internal combustion engine
the bessemer process
the dynamo

Explanation:

Question 1

• For the option "Electric lights made it possible for factories to run after dark": The light bulb provided artificial light, allowing factories to operate beyond daylight hours, which is a key impact on industry.
• "Having better lighting largely eliminated industrial accidents": Better lighting didn't largely eliminate accidents, as accidents had multiple causes.
• "Bulb manufacturing became the biggest industry in the US": Bulb manufacturing was important but not the biggest industry.
• "Brighter lights made people more productive so they worked fewer hours": There's no strong link between light brightness and working fewer hours due to productivity; longer working hours were common in industrialization. So the correct option is the first one.

• "The steam engine" was more prominent in the first Industrial Revolution.
• "The internal combustion engine" (used in cars, planes, etc.) revolutionized transportation in the second Industrial Revolution, enabling new modes like automobiles and aviation.
• "The Bessemer process" was about steel production, not transportation.
• "The dynamo" was about electricity generation, not direct transportation impact. So the internal combustion engine had the greatest impact.

Answer:

A. Electric lights made it possible for factories to run after dark
