Answer:
The scientists of the Industrial Revolution discovered ways to make machines much more efficient than people.
Step-by-step explanation:
The new science and technology of the Industrial Revolution allowed factory owners to produce goods much more quickly and cheaply than an individual craftsperson could. Factory owners used scientific discoveries and inventions to make their factories more productive and efficient; they were less concerned about a worker's craft skills since the worker would need to perform just one step toward creating the product--or perhaps just operate a machine that created the product.
