Shannon and Weaver's communication model was not focused on which of the following?

Shannon and Weaver's model was not focused on statements 2, 3 and 4.

Statement 2, the contents of messages, lay outside their concern, since they treated the message as signals to be carried.

Statement 3, the meanings of messages, was set aside because their engineering model deliberately bracketed interpretation.

Statement 4, the intention behind messages, likewise fell beyond a scheme built for accurate signal transfer.

Message transmission was the very heart of their model, so it was clearly within its focus.

The medium of transmission also mattered to them, as they studied which channels carry signals most effectively.
