Doctor : Nurse :: ? : Follower — Choose the word that pairs with “Follower” in the same leader–assistant relationship.

Introduction / Context:
Relationship analogies match roles that co-occur in hierarchies or coordinated tasks. “Doctor : Nurse” reflects a professional leadership/coordination relationship in clinical contexts. We need a corresponding pair where the first term stands in a guiding or leading relation to the second.

Given Data / Assumptions:

• The first pair suggests lead/coordinate (doctor) to support/assist (nurse).
• We must reproduce this asymmetry for “Follower.”
• Options present roles that may or may not mirror leadership.

Concept / Approach:
The natural counterpart of “Follower” is “Leader.” This preserves relational polarity: the first term directs or inspires; the second term follows or responds. Other options do not create the needed directional relation.

Step-by-Step Solution:
Identify relation: leader/guide vs supporter/follower.Pick the canonical opposite-complement: Leader : Follower.

Verification / Alternative check:
Common collocations and organizational structures pair “leader” with “follower,” analogous to doctor–nurse (though domain differs). The core is asymmetric role linkage, not identical professions.

Why Other Options Are Wrong:

• Worker/Employer/Union: Do not stand in a direct follower relation; relationships differ (employment, collective body).
• Guide: Close to leader, but the standard antonymic complement for “follower” is “leader.”

Common Pitfalls:
Forcing domain-specific pairings instead of preserving the abstract relational pattern.

Final Answer:
Leader
