Analogy — “Nail” is cut by a “Nail cutter”; in the same way, “Hair” is cut by ____. (Identify the tool used.)

Introduction / Context:
This is an instrument–action analogy. The first pair links an object to the tool that acts upon it: a “Nail” is trimmed by a “Nail cutter.” We need the equivalent tool for “Hair.”

Given Data / Assumptions:

• Nail cutter is a cutting instrument for nails.
• We require the standard instrument for cutting hair.

Concept / Approach:
“Scissors” (or sometimes “Razor”) cut hair; among options, “Scissors” is the canonical tool mapping best to the form of the first pair (object → hand tool).

Step-by-Step Solution:

Verification / Alternative check:
Barbering relies on scissors as the primary cutting instrument, keeping the analogy symmetrical with “nail cutter.”

Why Other Options Are Wrong:

Common Pitfalls:
Choosing a related grooming item (comb/oil) rather than the actual cutting instrument.

Final Answer:
Scissors
