Question

how did henry fords innovation pictured above affect american society?
a automobiles replaced railroads as the primary mode of transporting goods.
b industries adopted mass - production techniques making goods more economically available.
c u.s. agricultural output declines as more men went to work in factories.
d women joined the workforce to meet the increased demand for automobiles.

Explanation:

Henry Ford is known for introducing the assembly - line production method. This mass - production technique allowed for the efficient and cost - effective manufacturing of goods. Automobiles became more affordable, but railroads still had a significant role in transporting goods. There is no clear evidence that agricultural output declined mainly because of men going to work in factories (other factors like mechanization in agriculture also played a role). Women joining the workforce in large numbers to meet automobile demand was not the primary and most far - reaching impact of Ford's innovation. The mass - production techniques he popularized were adopted by many industries, making a wide range of goods more economically available.

Answer:

B. Industries adopted mass - production techniques making goods more economically available.
