Question

2 why was henry bessemers 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 countrys interior.

Explanation:

To solve this, we analyze Henry Bessemer’s invention (the Bessemer process, a steel - making innovation):

• Option A: The Bessemer process is about steel production, not revolutionizing communication. So A is incorrect.
• Option B: Interchangeable parts were developed by others (like Eli Whitney) and are not related to Bessemer's work. So B is incorrect.
• Option C: The Bessemer process made steel production cheaper and faster. Steel was a crucial material for railroad construction (for rails) and also for skyscrapers (as a strong building material, allowing cities to build upward). This option aligns with the impact of the Bessemer process.
• Option D: The Bessemer process has nothing to do with opening water routes to a country's interior. So D is incorrect.

Answer:

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