4. cultural diversity

Correct Ans: (C)

Explanation:
The ABX model, proposed by Theodore M. Newcomb in 1953, is a communication model that centers on interpersonal and group relationships. The model involves three elements:

• A and B are two communicators (individuals or groups),
• X is the subject or object they are both concerned with.

The primary objective of this model is to maintain balance or social equilibrium between the communicators. When both A and B have similar attitudes or beliefs about X, the communication flow remains smooth and balanced. However, if their views about X differ, it creates cognitive dissonance, leading to an imbalance or tension in the relationship.

Newcomb’s model introduces the idea that communication is a tool to restore balance. When a disagreement or conflict arises, individuals engage in dialogue to resolve it, aiming to realign their views and preserve the relational harmony. Thus, communication serves not only to exchange information but to maintain social structures and stability.

This theory is especially relevant in fields like media studies, political communication, and conflict resolution, where maintaining social harmony and consensus is often a key objective.

In short, the ABX model is not about protecting political systems or economic stability directly — its core aim is to use communication as a mechanism for sustaining social equilibrium.
