Answer:
steam powered engine
Explanation:
The Industrial Revolution was prompted by an invention that enabled the manual labor to be replaced with machinery. This invention was the steam powered engine. This engine enabled the machinery to be able to perform work, and not just to perform it, but to be much quicker, cheaper, and more efficient than the manual labor. The new invention of course needed human assistance as it was not able to work on its own, but it managed to improve and significantly speed up the manufacturing process, resulting in an economic boom and further development.
