Difficulty: Easy
Correct Answer: Highway : Asphalt
Explanation:
Introduction / Context:The relation is “product : primary material.” Shoes are commonly made of leather. We need the analogous material for highways.
Given Data / Assumptions:
Concept / Approach:Most highways are surfaced with asphalt (or concrete), making “asphalt” the standard material pairing parallel to “leather.”
Step-by-Step Solution:Identify material-level pairing, not worker or component.Select “Highway : Asphalt.”
Verification / Alternative check:Other choices are role–person or vehicle–component relations, not material–product.
Why Other Options Are Wrong:They mismatch relation types (e.g., doctor is a person, wagon is part of a train).
Common Pitfalls:Choosing a functional relation rather than a material relation.
Final Answer:Highway : Asphalt.
