Question

transmission of messages in a communication is: a. a one-way street. b. a two-way street.

I think it's b

Answer 1

You are correct. The listener hears through whatever "filters" or biases or knowledge he/she already has, so interprets the message provided by the speaker. What the speaker says may not be what the listener hears in every case.

Answer 2

Depending on the definitions of "street," I would disagree. If one person is the speaker, and one or more are just listeners, it would be a "one-way street, e.g., listening to radio or TV. There is no communication in the opposite direction, which is needed to make it a "two-way street."
