why was thomas edisons improvement to the light bulb important to the
industrial revolution?
a. it allowed employers to extend the workday and increase
productivity.
b. it created a demand for skilled glassblowers to make more light
bulbs.
c. it improved the safety by allowing railroad engines and
steamboats to have headlights.
d. it made gas resources available for manufacturing, since gaslights
were no longer needed.

Explanation:

Thomas Edison's improved light bulb (incandescent light bulb) provided a reliable, long - lasting, and relatively safe source of artificial light. Before this, lighting options like gas lamps had limitations. With electric light, workplaces could be illuminated at night, so employers could extend the workday. This led to an increase in the amount of work done (productivity) during the Industrial Revolution. Option B is incorrect because the demand for glassblowers wasn't the main impact on the Industrial Revolution. Option C is wrong as the main impact on the Industrial Revolution wasn't about railroad engines and steamboats' headlights. Option D is incorrect as the light bulb used electricity, not gas, and the shift from gas lights to electric lights didn't primarily free up gas for manufacturing in a way that was a key impact of the light bulb on the Industrial Revolution.

Answer:

A. It allowed employers to extend the workday and increase productivity.
