Analogy — choose the pair with the same “object moves along its guiding path” relation as Train : Track.

Introduction / Context:Analogies test your ability to identify a precise relationship and replicate it. “Train : Track” expresses an object that moves along a physical guiding path or channel specifically built for it. We must find a second pair that preserves both the category and the direction (object → guide/path).

Given Data / Assumptions:

• Stem: Train moves along Track.
• Look for object → guiding path/channel in the same order.
• Concept is physical motion constrained by a designed structure.

Concept / Approach:The correct choice should have a discrete moving object and a man-made guide through which it travels. The “Boat : Water” option swaps the order (medium first) and uses a natural medium, not a built-in guide. Precision matters in analogies.

Step-by-Step Solution:

Verification / Alternative check:Ask if removing the guide prevents proper operation. Without a barrel, a bullet would not be guided; without tracks, trains cannot run correctly. The dependency is analogous.

Why Other Options Are Wrong:

• Water : Boat — reversed and the second is an object, first is a natural medium.
• Idea : Brain — containment/processing, not motion along a guide.
• Fame : Television — abstract relation, not a guided path.

Common Pitfalls:Accepting “medium” for “guide” or ignoring the order. Ensure both structural guidance and correct term sequence match the stem pattern.

Final Answer:Bullet : Barrel
