Difficulty: Easy
Correct Answer: tire : automobile
Explanation:
Introduction / Context:
A PEDAL is a component or part of a BICYCLE. The required relationship is 'part : whole.' We need a similar mechanical component that belongs to a larger object in the same direction.
Given Data / Assumptions:
Concept / Approach:
Check which options are parts of the named whole. Discard unit–measure, action–action, or tool–vehicle relations that do not preserve part–whole structure.
Step-by-Step Solution:
1) Identify pattern: part → whole.2) 'tire : automobile' fits, as a tire is a part of a car.3) 'inch : yardstick' is unit vs. measuring device, not a component.4) 'walk : skip' are actions, not part–whole.5) 'buckle : belt' is also part–whole, but introduces ambiguity across apparel rather than machinery; the more precise vehicle-component analogy is superior and conventional for test items.6) 'oar : canoe' is an accessory used with a canoe but not a fixed component of the canoe; it is detachable equipment.
Verification / Alternative check:
Sentence test: 'A pedal is part of a bicycle' and 'A tire is part of an automobile' are standard statements of composition in mechanical contexts.
Why Other Options Are Wrong:
Common Pitfalls:
Beware of accessory relationships. The correct choice should reflect a built-in component similar to how a pedal belongs to a bicycle.
Final Answer:
tire : automobile
