Analogy — select the pair with the same “place for vehicle” relationship as Platform : Train.

Introduction / Context:
This verbal analogy asks you to recognize the relationship between two words and choose another pair that follows the same logic. The reference pair is “Platform : Train,” which describes a dedicated place or structure used by a particular mode of transport for boarding, alighting, or berthing.

Given Data / Assumptions:

• The stem pair is Platform : Train.
• We need another pair where the first term is a place or structure and the second term is the vehicle that uses it.
• Transport-domain terms should be interpreted in their common, practical sense.

Concept / Approach:
Identify the precise relation: a platform is the facility used by a train at a station. We then look for an option where the first word is the corresponding facility and the second is the vehicle that uses that facility. Keep order in mind (place → vehicle), not the reverse.

Step-by-Step Solution:

Verification / Alternative check:
Replace words with definitions: “Place for trains : train” vs “Place for ships : ship.” The logical structures align perfectly, confirming the choice.

Why Other Options Are Wrong:

• Aeroplane : Aerodrome — reversed order (vehicle : place), unlike the stem.
• Hotel : Tourist — place : person, not place : vehicle.
• Footpath : Traveller — place : person, not place : vehicle.

Common Pitfalls:
Ignoring the order of terms or accepting a plausible domain without matching the exact relation (vehicle vs. person). Always preserve the same role and direction.

Final Answer:
Quay : Ship
