Final answer:
The method of organizing a message that begins with familiar information and moves to unfamiliar information is known as Known-to-unknown.
Step-by-step explanation:
The method of organizing a message that begins with information familiar to the audience before moving to unfamiliar information is known as Known-to-unknown. This approach is used to engage the audience by starting with what they already know, establishing a connection, and then introducing new information in a logical and structured manner.
By using the Known-to-unknown method, the writer or speaker can build on the audience's existing knowledge, making the message more relatable and comprehensible. This approach helps avoid overwhelming the audience with unfamiliar information right from the start.
Here's an example: If you were giving a presentation on the solar system to a class, you might begin by asking the students what they already know about the planets. Once you have established their prior knowledge, you can then expand on it by introducing new and more complex information about each planet.
