Question

in the 1920s, how did manufacturers make products faster and more cheaply?
○ they reused old designs and models.
○ they offered a smaller range of goods.
○ they saved on costs by not advertising as much.
○ they adopted henry ford’s manufacturing techniques.

Explanation:

In the 1920s, Henry Ford's assembly line manufacturing technique revolutionized production by standardizing processes, allowing for faster, mass-produced goods at lower costs. The other options do not align with the key innovation that drove faster, cheaper production in this era: reusing old designs did not speed up production, a smaller range of goods was a result not a method, and reduced advertising would not improve production speed.

Answer:

D. They adopted Henry Ford's manufacturing techniques.
