Emotion and expression mapping: “Tragedy : Sadness : Tears”. Choose the triad that mirrors cause → emotion → outward expression.

Introduction / Context:
Affective analogies relate a trigger or genre to the emotion it evokes and then to a characteristic outward expression. “Tragedy : Sadness : Tears” follows cause/genre → emotion → expression. The correct option should mirror this path with a different genre and the corresponding emotional outcome and expression.

Given Data / Assumptions:
We assume typical audience reactions under normal contexts (no irony/satire confounds).

Concept / Approach:
“Comedy : Humour : Laughter” precisely parallels the structure: comedy (cause/genre) leads to a feeling of amusement/humour (emotion), which commonly produces laughter (expression). Each term aligns role-for-role with the original triad.

Step-by-Step Solution:

Verification / Alternative check:
“Music : Emotion : Tune” is ill-posed; “tune” is a musical element, not an expression. “Dance : Rhythm : Grace” describes qualities rather than emotion→expression. The offered “Fear : Shock : Smile” contradicts typical expression mapping (smile does not usually follow fear/shock).

Why Other Options Are Wrong:
They fail to express a clean chain from cause to emotion to a canonical outward expression.

Common Pitfalls:
Confusing art-form descriptors with audience emotions and expressions.

Final Answer:
Comedy : Humour : Laughter
