Analogy — Emollient : Soothe Choose the pair with the same agent–function relationship.

Introduction / Context:
An “emollient” is a substance used to soothe or soften (especially skin). The relationship is agent (or instrument) → function. We must select a second pair that preserves this “thing performs action” mapping.

Given Data / Assumptions:

• Emollient performs the function “soothe.”
• We seek a device or agent whose core function is expressed by the verb.

Concept / Approach:
Filter for a clear instrumentality relation: X is something that does Y. Reject pairs where the left term is not an agent/device, or where the right term is not the function.

Step-by-Step Solution:

Verification / Alternative check:
Dictionary senses align: emollient → soothe; dynamo → generate (power). The relational pattern is parallel.

Why Other Options Are Wrong:

• Elevation : Level — category mismatch.
• Hurricane : Track — role reversal; humans track hurricanes.
• Precipitation : Fall — process/result, not instrumentality.

Common Pitfalls:
Mistaking any co-occurring terms for the stricter agent-performs-function mapping.

Final Answer:
Dynamo : Generate
