In the following analogy question, select the related word pair from the given alternatives: Gun : Soldier :: ? : ?

Introduction / Context:
This verbal analogy question compares a tool with the person who commonly uses it in a professional context. You are given Gun and Soldier and must find the pair that shows the same relationship from the options. Recognizing worker tool relationships is a common requirement in aptitude and reasoning sections of competitive exams.

Given Data / Assumptions:
- The first pair is Gun and Soldier, where a gun is a weapon used by a soldier in the line of duty.
- The required pair must show a similar professional relationship between a person and the tool that person normally uses.
- The options pair various tools or objects with different professions: Pen with Carpenter, Plough with Surgeon, Chisel with Sculptor, and Sword with Doctor.
- We assume standard occupational roles, not rare or metaphorical uses.

Concept / Approach:
The central concept is to see Gun as the primary working tool or weapon of a Soldier. The second pair must therefore present a tool that is closely and characteristically used by a particular professional. Among the given alternatives, you should look for the pair where the first word is a tool and the second word is a professional whose main work depends on that tool, just as a soldier depends on a gun in combat situations.

Step-by-Step Solution:
Step 1: Identify the relationship in the first pair. A soldier is a trained professional in the armed forces, and a gun is a central weapon used by the soldier.Step 2: Examine each option to see which tool fits naturally with the professional listed.Step 3: Pen : Carpenter does not match, because a carpenter primarily uses tools such as saws, hammers, and chisels, not a pen.Step 4: Plough : Surgeon is incorrect, because a plough is an agricultural tool, while a surgeon uses medical instruments like scalpels.Step 5: Chisel : Sculptor is a strong match, because a sculptor regularly uses a chisel to shape stone or wood, just as a soldier regularly uses a gun.Step 6: Sword : Doctor does not match, since doctors use medical equipment and have no professional connection with swords.Step 7: Therefore Chisel : Sculptor is the correct pair that mirrors Gun : Soldier.

Verification / Alternative check:
You can restate each pair in a sentence to verify the relationship. A soldier uses a gun as a main weapon. Similarly, a sculptor uses a chisel as a main tool for shaping material. The sentences for the other options sound unnatural or incorrect. For example, a carpenter does not normally use a pen as a primary tool, and a doctor does not use a sword. This sentence based check confirms the similarity between the original pair and Chisel : Sculptor.

Why Other Options Are Wrong:
- Pen : Carpenter: A pen is typically associated with writers, clerks, or students, not with carpenters whose central tools are woodworking instruments.
- Plough : Surgeon: A plough belongs to farming, while a surgeon belongs to medicine, so there is no functional parallel with gun and soldier.
- Sword : Doctor: A sword is a weapon, but it is unrelated to the professional duties of a doctor, who uses stethoscopes and surgical tools.

Common Pitfalls:
Some learners quickly match two words that individually make sense but do not check the exact nature of the relationship. The exam requires a precise type of link, here tool to professional user. To avoid mistakes, always ask what role each word plays and whether that role is mirrored exactly in the answer pair. Matching domains superficially without checking functional similarity is a frequent reason for wrong choices in verbal analogy questions.

Final Answer:
The pair that shows the same relationship as Gun : Soldier is Chisel : Sculptor because both pairs relate a professional to a primary working tool.
