Car is to garage as aeroplane is to which of the following places of storage.

Introduction / Context:
This analogy checks knowledge of specific terms for places where different vehicles are kept. A car is kept in a garage, so we must find the corresponding place where an aeroplane is stored when not in flight. The question tests both vocabulary and general knowledge related to transportation and infrastructure.

Given Data / Assumptions:

• First pair: Car : garage.
• Garage is a building or covered shelter where cars and small vehicles are parked or stored.
• Second pair: Aeroplane : ?
• Options: Hangar, Port, Harbour, Depot.
• We assume standard terminology used in aviation and transport.

Concept / Approach:
The pattern is “vehicle is to its housing or shelter.” We must recall the specific word used in aviation for a large building where aircraft are stored and maintained. That term is hangar. Port usually refers to a seaport for ships, harbour is also related to ships and boats, and depot tends to be associated with bus or rail facilities, not primarily aircraft. Therefore, hangar is the precise parallel to garage in the context of aeroplanes.

Step-by-Step Solution:
Step 1: Understand that garage is a shelter or building for cars. Step 2: Identify that we need a similar shelter type for aircraft. Step 3: Recall that aircraft are usually parked, repaired and maintained in large structures called hangars. Step 4: Compare other options. Port and harbour refer to places used for ships and boats. Step 5: Note that depot is more general and used mostly for buses or trains, so hangar is the most accurate match.

Verification / Alternative check:
We can phrase the pairs as ordinary sentences. We say “Cars are kept in garages” and “Aeroplanes are kept in hangars.” These sound correct and are commonly used in everyday language and aviation contexts. By contrast, “Aeroplanes are kept in ports” or “Aeroplanes are kept in harbours” are not accurate, because ports and harbours are connected with water transport. “Aeroplanes are kept in depots” is also not the standard expression; aviation companies and airports speak of hangars instead.

Why Other Options Are Wrong:

• Port: A facility where ships dock; related to sea transport, not aircraft storage.
• Harbour: A sheltered area of water for ships, again unrelated to aeroplane storage.
• Depot: A general term for a storage or maintenance location, but not the specific technical word for aircraft housing.

Common Pitfalls:
Some learners may pick depot because it sounds like a store house and is associated with transport. However, verbal analogy questions often expect the most specific technical term rather than a vague one. Remembering the exact word used for aircraft storage, hangar, shows higher precision in vocabulary and matches the pair car : garage much more closely in terms of specificity.

Final Answer:
The correct completion is Aeroplane : Hangar, so the analogy becomes Car : garage :: Aeroplane : hangar.
