1. why was henry bessemer’s invention important? a. it revolutionized communication. b. it allowed machines to be made with interchangeable parts. c. it allowed the railroads to grow quickly and cities to build upward. d. it opened up a water route to the country’s interior.

Explanation:

Henry Bessemer's invention was the Bessemer process for mass - producing steel. Steel was a crucial material for building railroads (which could then grow quickly) and for constructing skyscrapers (cities building upward). Option A is incorrect as his invention was not about communication. Option B refers to interchangeable parts, which was not his contribution. Option D is about water routes, which is not related to his steel - making invention. So the correct option is C.

Answer:

C. It allowed the railroads to grow quickly and cities to build upward.
