Question

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

Explanation:

The telegraph used electrical signals to transmit messages. Before it, communication over long - distances was slow (e.g., by mail). With the telegraph, messages could be sent and received almost immediately across large geographical areas. It was a text - based communication (not voice, so "People could speak to each other over great distances" is wrong). It was mainly for short messages (not "Large amounts of information"), and while it could aid newspapers (by providing quick news), its core significance was instant long - distance communication.

Answer:

People could communicate instantly over great distances.
