Answer:
True.
Step-by-step explanation:
In order for a Communication to be successful, both the speakers and the recipient need to possess all the means necessary to transfer the message.
The speaker need to possess the ability to break down the message into something that can be understood by the recipient, and the recipient need to possess the knowledge and attention to digest the message.
For example, let's say that Bob is a cardiologist .
He has a patient who has no background in medical education at any point in his life. In order to convey an information about his patient's heart condition, Bob need to avoid the use of complicated medical terms to his patient. Otherwise his effort to communicate the information wouldn't be understood by the patient.
