Difficulty: Easy
Correct Answer: key : piano
Explanation:
Introduction / Context:Analogies often test knowledge of how components make up a whole. BRISTLE : BRUSH indicates that bristles are parts that make up a brush. We must find a similar part-to-whole relationship.
Given Data / Assumptions:
Concept / Approach:
Step-by-Step Solution:
1) Identify the relationship: bristle (part) belongs to brush (whole).2) Check options: 'arm : leg' are coordinate parts of a body, not part-to-whole within the same object relationship.3) 'stage : curtain' are associated stagecraft items, not part-to-whole in one object.4) 'recline : chair' is action-to-object, not component-to-whole.5) 'key : piano' shows a key as a component of a piano — part-to-whole mapping.6) 'art : sculpture' is category-to-member; not analogous.Verification / Alternative check:
Composition test: Pianos consist of keys; brushes consist of bristles. Both first terms are integral parts of the second.Why Other Options Are Wrong:
arm : leg — neither is the whole for the other.stage : curtain — separate items; not the same whole.recline : chair — verb–noun relation.art : sculpture — class-to-instance, not part-to-whole.Common Pitfalls:
Mistaking mere association for physical composition.Final Answer:
key : piano
