Question

which of the following best describes the significance of the telegraph in revolutionizing communication?
people could communicate instantly over great distances.
newspapers could report on events in other states.
large amounts of information could be sent to remote areas.
people could speak to each other over great distances.

Explanation:

The telegraph used electrical signals to transmit messages. Before it, communication over long distances was slow (e.g., letters by horse - drawn carriages). With the telegraph, messages could be sent and received almost instantly across large geographical areas. Newspapers reporting on events in other states was a secondary effect. Sending large amounts of information to remote areas was not its main revolutionary aspect compared to instant communication. And people could not speak to each other over great distances with the telegraph (that was the telephone).

Answer:

People could communicate instantly over great distances.
