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:

To determine the correct answer, we analyze each option:

• "the use of hand - crafted products": Hand - crafted products are made one at a time and are not suitable for mass production. So this option is incorrect.
• "the use of specialized labor": Specialized labor is about workers having specific skills, but it alone doesn't enable mass production in the way the question is asking. It's more about the division of labor in a different context.
• "the use of expensive materials": Using expensive materials would likely hinder mass production as it would increase costs and limit the quantity that can be produced.
• "the use of interchangeable parts": In the early 1800s, Eli Whitney popularized the use of interchangeable parts. This allowed parts to be made uniformly, so they could be easily assembled and replaced, which was a key factor in making mass production possible.

Answer:

A. the use of interchangeable parts
