Analogy completion — choose the best word to complete the relationship: fence, wall → boundary :: path, alley → __

Introduction / Context:
This analogy examines category recognition for built-environment terms. A fence and a wall are both types of boundaries; similarly, a path and an alley are types of what? Identifying the higher-level category that subsumes the given examples is the key.

Given Data / Assumptions:

• Fence/wall → boundary (category).
• Path/alley → __ (seek the relevant category).
• All terms concern human movement and spatial demarcation.

Concept / Approach:
Abstract the examples to a hypernym. 'Fence' and 'wall' define or restrict space, so 'boundary' fits. 'Path' and 'alley' are ways or corridors for movement from one place to another, so a fitting category is 'passageway.' Choose the broader, neutral term that covers both a small footpath and a narrow urban lane.

Step-by-Step Solution:

Verification / Alternative check:
Check alternatives: 'thoroughfare' often implies a main road open to general traffic, which can be too large or vehicular; 'ramp' is a sloped surface; 'airfield' is unrelated; 'pedestrian' is an adjective/noun, not a place category. 'Passageway' best covers both 'path' and 'alley.'

Why Other Options Are Wrong:

• ramp: a specific structure, not the class containing both path and alley.
• airfield: unrelated domain.
• pedestrian: describes people or foot traffic, not the route itself.
• thoroughfare: usually larger/vehicular; does not neatly include narrow paths.

Common Pitfalls:
Choosing a word that is related to movement but not the correct category level. Always match the hypernym role used in the first mapping.

Final Answer:
passageway
