Analogy — Launcher : Missiles Select the device–projectile relation that matches.
Correct Answer: Catapult : Stone
Introduction / Context:“Launcher : Missiles” expresses a device designed to propel a specified projectile. We must find a parallel pair with a device that launches/propels its characteristic projectile.
Given Data / Assumptions:
- Launcher → launches missiles.
- Parallel should be device → its projectile/object launched.
Concept / Approach:Discard pairs where the second term is not the projectile, where the first term is not the device, or where both are co-hyponyms (same category items) rather than device–output.
Step-by-Step Solution:
“Catapult : Stone” — a catapult propels stones/bolts; matches device–projectile.“Gun : Revolver” — both are firearms; revolver is a type of gun (category conflict).“Boat : Anchor” — anchor is dropped, not launched as a projectile.“Engine : Train” — engine powers a train, not a projectile relation.Verification / Alternative check:History and physics examples list catapults launching stones, analogous to missile launchers launching missiles.
Why Other Options Are Wrong:
- Gun : Revolver — hyponymy, not device–projectile.
- Boat : Anchor — function is mooring, not launching.
- Engine : Train — traction, not projectile.
Common Pitfalls:Confusing “powers/contains” relations with “launches/propels.”
Final Answer:Catapult : Stone
