“Sound” that has been “Muffled” is a diminished/softened version. Choose the pair that similarly expresses a quality reduced in its intensity or vividness.

Introduction / Context:Qualitative analogies map an item to a reduced-intensity state. “Muffled” describes sound that is softened or dulled. We need a parallel where a sensory attribute is comparably diminished from its full intensity or saturation.

Given Data / Assumptions:

• Muffled sound = softened/dulled sound.
• Look for a similar reduction in a visual attribute.

Concept / Approach:“Colour : Faded” matches perfectly: a faded colour is reduced in vividness/saturation. Other options do not represent reduction: “Moisture : Humid” indicates presence, not reduction; “Despair : Anger” are different emotions; “Odour : Pungent” is intensified rather than reduced.

Step-by-Step Solution:1) Abstract the relation: stimulus → diminished quality.2) Choose a parallel in the visual domain.3) Select “Colour : Faded.”

Verification / Alternative check:In everyday descriptors, “muffled” and “faded” are prototypical terms for reduced intensity in hearing and sight respectively.

Why Other Options Are Wrong:

• Moisture : Humid: Indicates high moisture, not reduced.
• Despair : Anger: Not a reduction relation.
• Odour : Pungent: Increased intensity, opposite of the intended mapping.

Common Pitfalls:Confusing any association with the specific “reduced intensity” relation.

Final Answer:Colour : Faded
