Correct response: A device designed to transmit electromagnetic waves through the air should be developed.
Explanation: In order to allow one user to hear the voice of another user at a distance of 5 kilometers, electromagnetic waves need to be transmitted through the air to carry the sound information. This can be achieved by developing a device that is capable of transmitting electromagnetic waves over long distances.
