Question

this excerpt is about technological innovation in the steel industry.
bessemers famous one - step process for producing cheap, high - quality steel made it possible for engineers to envision transcontinental railroads, sky - scraping office towers, bay - spanning bridges, unsinkable ships, and mass - produced horseless carriages....
steel was the obvious choice of metal to replace cast iron. yet it was only producible in small batches, and the extremely high temperatures required to burn off impurities... required large amounts of costly fuels....
... as he refined the process, bessemer found that his steel was lighter and easier to shape than traditionally made metals, and that he could produce far greater quantities of it at a rate 10 times faster.
—michael macrae, \henry bessemer,\ the american society of mechanical engineers, 2012
how did the bessemer process influence the u.s. economy?
a it expanded the use of automation instead of workers.
b it increased reliance on foreign imports of machinery.
c it created growth through infrastructure development.

Explanation:

The text mentions that Bessemer's process made it possible for engineers to envision large - scale infrastructure projects like transcontinental railroads, skyscrapers, bridges, etc. These infrastructure projects are key to economic growth as they create jobs, facilitate trade (railroads), and attract businesses (skyscrapers for offices). Option A is incorrect as there is no mention of automation replacing workers. Option B is wrong because the text is about a domestic (Bessemer's) process, not foreign imports.

Answer:

C. It created growth through infrastructure development.
