Which of the following should NOT be a part of clear text language during communication?

The correct choice highlights that using complex jargon should not be part of clear text language during communication. Clear text language is designed to ensure that the message is understood easily by all participants. This is especially crucial in emergency situations, like those faced by airport fire rescue teams, where miscommunication can have serious consequences.

Complex jargon often involves specialized terms or phrases that may not be familiar to everyone involved in the conversation. This can lead to confusion or misinterpretation of critical information. Drawing on language that is straightforward and accessible helps to ensure that all parties, regardless of their background or level of expertise, can grasp the intended message quickly and easily.

In contrast, a calm and distinct speaking style, a low pitch voice, and moderate speed help enhance clarity and comprehension when communicating in high-pressure scenarios. These aspects contribute to creating an atmosphere where effective and ongoing communication can take place, ultimately leading to better coordination during critical operations.
