Answer 2

The telephone allowed for voice communication over a distance.

Step-by-step explanation:

Telegraph communication was the first medium that was instant in communications. It transmitted messages by means of electrical impulses that circulated through a single cable by using morse code to decode the messages, but it did not send voice signals, the telephone allowed that, since a telephone converts sound into electronic signals that are transmitted via cables to another telephone which reproduces the sound.
