Q.5 Select the pair that best expresses a relationship similar to that expressed in the pair:

water : pipe ::

• (A) cart : road
• (B) electricity : wire
• (C) sea : beach
• (D) music : instrument
  

  Solving the Analogy: Water : Pipe

  This is a classic analogy question testing proportional relationships. “Water : pipe” means water flows through a pipe, which acts as its conduit or medium for transport. We need to find the pair with the same “substance : conduit” dynamic.

  Option Analysis

  • (A) cart : road: A cart travels on a road, not through it. Roads support movement but aren’t a channel for flow. No match.

  • (B) electricity : wire: Electricity flows through a wire, just like water through a pipe. Wires conduct electrical current as pipes conduct water. Best match.

  • (C) sea : beach: The sea borders or meets the beach. No flow-through relationship; beach contains or touches the sea. Poor fit.

  • (D) music : instrument: Music is produced by an instrument, not flowing through it. Instruments create sound, not channel it like a pipe. Incorrect.

  Correct Answer: (B) electricity : wire

  Introduction to Water Pipe Analogy in Reasoning Questions

  The water pipe analogy is a staple in verbal reasoning and aptitude tests, where “water : pipe” represents a substance flowing through a conduit. Just as water travels through pipes in plumbing systems, we seek similar pairs like electricity : wire. This question sharpens pattern recognition skills, vital for exams. Let’s dive into the full explanation.

  Why Water Flows Through Pipes: The Core Relationship

  Pipes are designed as hollow channels for liquids like water to flow seamlessly from source to destination. This “flow through a medium” defines the water pipe analogy. No spillage, direct transport—think household plumbing or irrigation.

  Breaking Down Each Option in Water Pipe Analogy

  Here’s a step-by-step evaluation:

  • Option A: Cart : Road
    Carts move on roads for support and direction. Roads don’t enclose or channel like pipes. Mismatch in “on vs. through.”

  • Option B: Electricity : Wire (Correct)
    Electricity currents flow through conductive wires, powering homes and devices. Mirrors water in pipes perfectly—both rely on enclosed pathways for efficient transmission.

  • Option C: Sea : Beach
    Seas touch beaches at the shore. It’s adjacency, not conduction or flow. Waves crash onto beaches, breaking the pattern.

  • Option D: Music : Instrument
    Instruments produce music via vibration. Music doesn’t “flow through” like a fluid or current. It’s creation, not transport.

  Real-World Examples to Master the Analogy

  • Water : Pipe → Rivers channeled through aqueducts (ancient Rome’s engineering marvel).

  • Electricity : Wire → Power grids sending volts through copper cables without loss.
    Compare: Gas : Pipeline follows the same logic!

  Tips for Solving Analogy Questions Like Water Pipe Analogy

  1. Identify the relationship (e.g., “flows through”).

  2. Test each option strictly.

  3. Eliminate mismatches quickly (support vs. channel).

  4. Practice with variations: Air : Windpipe or Oil : Pipeline.

  Perfect for GATE, SSC, or bank exams—boost your score!
