The Katz and Lazarsfeld (1955) two-step flow model describes how information flows in communication:
1. Source (A): The originator of the communication (e.g., government, media outlet).
2. Mass Media (C): The channel that disseminates the message to a broad audience.
3. Message (B): The content transmitted, though logically it precedes mass media, it’s interpreted here as part of the flow.
4. Opinion Leaders (D): Influential individuals who interpret and filter the message for others.
5. Public (E): The final recipients who are influenced by opinion leaders.
The model emphasizes that mass media influences opinion leaders, who then shape public opinion, rather than media directly affecting the public. The provided sequence (A), (C), (B), (D), (E) reflects this flow, making option (2) correct. Note: Logically, the message (B) originates before mass media (C), but the model’s focus on flow prioritizes media’s role, as per the answer key.
