Analogy — “Blood” flows through a “Vein”; similarly, “Oil” flows through ____. (Identify the conduit.)

Difficulty: Easy

Correct Answer: Pipelines

Explanation:

Introduction / Context:Conduit analogies match a substance with the channel it travels through. Blood flows in veins; we need the industrial conduit for oil.

Given Data / Assumptions:

  • Veins carry blood within organisms.
  • Pipelines carry oil across distances in industry.

Concept / Approach:Map substance → conduit: “Oil → Pipelines.”

Step-by-Step Solution:

1) Recognize relation: content → carrier/conduit.2) Choose “Pipelines” as the industrial equivalent of “veins.”3) Exclude usage sites or other transport modes when a direct conduit is offered.

Verification / Alternative check:Pipelines are primary infrastructure for continuous oil transport, paralleling veins as biological conduits.

Why Other Options Are Wrong:

Car/Engine: users/containers of oil, not conduits.Petrol: refined product, not a conduit.Tanker: vehicle, not a fixed conduit like “vein.”

Common Pitfalls:Confusing end-use machinery with transport conduits.

Final Answer:Pipelines
