Answer:
a) True
Step-by-step explanation:
Although humans rely heavily on language to understand and connect with each other, this is not the only way in which humans can exchange information. One of the most important skills that humans use to fulfill this purpose is the use of nonverbal behaviours. This includes actions such as face expressions, hand gestures and postures. The purpose of such means of communication is to facilitate service and task goals by adding on or substituting the information that is communicated verbally.
