Analogy — Suggestion : Order\nPick the option that preserves a graded intensity relation (weaker form to stronger form) within the same domain.

Introduction / Context:
The pair “Suggestion : Order” demonstrates a gradation of force within directives: a suggestion is a mild, optional prompt, whereas an order is a strong, mandatory directive. The correct analogous pair should likewise move from a milder instance to a stronger instance within the same semantic field.

Given Data / Assumptions:

• The relation is not antonymy or cause–effect but degree/intensity within a category.
• Both terms should belong to the same type (e.g., both directives, both expressions).
• The second term should represent a stronger or more intense version of the first.

Concept / Approach:
We compare candidate pairs for clear scalar escalation. We avoid pairs that switch categories (plan vs implement) or that present unrelated process chains (emotion vs act) lacking a clean intensity ladder.

Step-by-Step Solution:

Verification / Alternative check:
In common usage, smiling is subdued compared to laughing, making this pair a close structural match to suggestion versus order as milder versus stronger forms.

Why Other Options Are Wrong:

• Advise : Suggest — similar modality; lacks a clear weaker-to-stronger progression.
• Plan : Implement — category shift from planning to doing.
• Anger : Shout — mismatched categories; an emotion may cause shouting but is not a stronger form of it.

Common Pitfalls:
Confusing cause–effect or process relations with graded intensity within a single domain.

Final Answer:
Smile : Laugh
