Analogy — Choose the materials-to-constructed-object relation: Straws : Nest

Introduction / Context:
“Straws : Nest” conveys a material → constructed object relationship. Birds use straws/twigs as building material to construct a nest. We must find a pair where the first item is the primary material from which the second item is made.

Given Data / Assumptions:

• Nest is built using straws or similar fibrous materials.
• Look for a clear “inputs form output” construction link.

Concept / Approach:
Identify which option presents “raw/input material → finished/constructed product,” avoiding pairs that express location, membership, or process flow rather than fabrication.

Step-by-Step Solution:
(a) Water : Stream → stream contains water; that is a flow/formation relation, not fabrication.(b) Animals : Zoo → occupants vs place (location), not material→product.(c) Threads : Cloth → threads are woven into cloth; perfect material→constructed object mapping.(d) Wood : paper → wood is a raw material for paper, but capitalization/spelling aside, industrial pulping is less direct. Still, (c) is the clearest straightforward fabrication analogue.

Verification / Alternative check:
Both “straws→nest” and “threads→cloth” are textbook examples in analogy questions illustrating material-to-fabricated object via assembly/weaving.

Why Other Options Are Wrong:
(a) Hydrological relation; (b) inhabitants vs enclosure; (d) while true in industry, the direct everyday construction parallel is better captured by (c).

Common Pitfalls:
Choosing location or containment relations that feel associated but lack the build/construct mechanism.

Final Answer:
Threads : Cloth
