Two-way communication is best described as:

• A. Exchange of information between diverse cultures.
• B. One-way transmission of data within a community.
• C. The process of water mixing with other liquids.
• D. A method for isolating environmental pollutants.

Answer: (A)

Two-way communication is a back-and-forth exchange where messages are sent and received, with feedback that confirms understanding or prompts clarification. Describing it as an exchange between diverse cultures highlights that meaning is negotiated across different backgrounds, so both sides interpret, respond, and adjust to ensure mutual understanding. The key idea is the active participation of both sender and receiver, not just transmitting information.

One-way transmission stops at delivering the message and lacks the response needed to verify comprehension. The other options refer to physical processes or environmental topics that have nothing to do with how people share and interpret information.
