Question

how might a factory worker in the late 19th century use the bessemer process in their work?
by enhancing agricultural output
by improving communication with the telegraph
expanding the railroads
by increasing the production of steel

Explanation:

The Bessemer Process was a method for mass - producing steel. In the late 19th century, factories used this process to make steel more efficiently. Steel was crucial for building railroads (as steel rails were stronger than iron ones). While agriculture (related to farming tools etc., but not directly the Bessemer Process), telegraph (communication, not steel production) are different areas. The key is that the Bessemer Process was about steel production.

Answer:

By increasing the production of steel
