Analogy — identify the “flows/feeds into” relation similar to River : Ocean.

Introduction / Context:
“River : Ocean” captures a directional, physical relationship: rivers typically flow into oceans. We seek a pair where the first entity consistently feeds into or connects into the second in a similar hierarchical or networked way.

Given Data / Assumptions:

• Rivers discharge into oceans or seas.
• We want a transportation or pathway analogy with a smaller way feeding into a larger way.
• Order matters: smaller → larger.

Concept / Approach:
Within road networks, a lane (narrow minor way) commonly leads into a road (broader, major way). This mirrors the hydrological network from tributaries to main bodies of water.

Step-by-Step Solution:

Verification / Alternative check:
Consider map topology: lanes typically connect to roads, just as rivers connect to oceans. Direction is preserved in practical layouts.

Why Other Options Are Wrong:

• Child : School — attendance, not a structural flow or network feed.
• Book : Library — storage relationship, not pathway connection.
• Cloth : Body — covering, not feeding into a larger system.

Common Pitfalls:
Confusing general association with directional network relations. Ensure a smaller pathway connects into a larger one, paralleling river systems.

Final Answer:
Lane : Road
