In Shannon and Weaver’s model of communication, level C deals with the problem of:
- transmission
- effectiveness
- entropy
- correction
Correct Ans: (B)
Explanation:
Shannon and Weaver’s model, one of the foundational communication models, includes three distinct levels: technical (Level A), semantic (Level B), and effectiveness (Level C). While the earlier levels address how a message is transmitted and understood, Level C focuses on the outcome — whether the message achieves its intended effect on the receiver.
More specifically, Level C answers the question: Did the communication succeed in changing opinions, behaviors, or actions? This makes it especially relevant in mass communication, advertising, public relations, and political messaging.
For example, if a public health campaign transmits a clear message (Level A) that the audience correctly interprets (Level B), it still might fail at Level C if people don’t take the desired action, like getting vaccinated. Thus, effectiveness goes beyond clarity; it deals with persuasion and audience response.
Communication at this level involves several factors: emotional appeal, timing, audience values, and message framing. It also considers feedback, which helps the sender gauge success and adjust strategies if needed.
In conclusion, Level C is vital because it measures real-world impact, not just technical success. Without effectiveness, even the most flawlessly delivered message can fall short of its goal — highlighting why communicators must prioritize audience engagement alongside message clarity.
