Question

what method of manufacturing, introduced in the early 1800s, made mass production possible?
○ the use of interchangeable parts
○ the use of hand - crafted products
○ the use of specialized labor
○ the use of expensive materials

Explanation:

In the early 1800s, the introduction of interchangeable parts allowed for the efficient assembly of products, enabling mass production. Hand - crafted products are for individual, non - mass production. Specialized labor is about worker skills, not a manufacturing method for mass production. Expensive materials don't enable mass production. So the correct option is the one about interchangeable parts.

Answer:

A. the use of interchangeable parts
