Analogy — Instrument and its function: Pen : Write

Introduction / Context:
The relation is tool→its primary action. A pen is used to write; we need another pair that preserves tool→action.

Given Data / Assumptions:

• Pen → write.
• Oar → used to row a boat.

Concept / Approach:
Match an implement with the verb denoting what one does with it.

Step-by-Step Solution:

Why Other Options Are Wrong:

• Knife : Plate: object–object, not tool–action.
• Chair : Table: two objects; no action relation.
• Worker : Factory: person–place.
• None of these: incorrect because “Oar : Row” fits.

Common Pitfalls:
Choosing object–object relations instead of instrument–function.

Final Answer:
Oar : Row
