Which two words can be used to interrupt a lower priority interphone message?

The correct response is based on the need for effective communication protocols in intercom systems, especially in environments where multiple messages can be transmitted simultaneously, such as an emergency situation or a busy control center. Using the words "EMERGENCY" or "CONTROL" serves an important purpose.

When one of these keywords is used, it alerts the intercom system and its users that the message being delivered has a higher priority than what is currently being communicated. This ensures that urgent messages are heard and acted upon without unnecessary delay, as they take precedence over lower priority communications. Understanding the significance of these terms helps facilitate efficient communication and urgent response protocols in critical scenarios.
