Difficulty: Medium
Correct Answer: Sister : Family : Brother
Explanation:
Introduction / Context:Relational analogies can represent hierarchical membership. A “class” is a defined subgroup within a “school”, and a “student” is a member of the school community. We want a triad that similarly presents “member(s)/subgroup : larger collective : member(s)”. The best human-social parallel is “Sister : Family : Brother”.
Given Data / Assumptions:We treat both “class” and “student” as members within the school structure, one collective (class) and one individual (student).
Concept / Approach:Prefer a triad where the middle is the higher-level collective and the flankers are elements within it. “Sister : Family : Brother” fits perfectly: family is the collective; sister and brother are members. The structural mapping matches the school case closely in terms of membership logic.
Step-by-Step Solution:
1) Abstract the pattern to membership within a collective. 2) Test alternatives for the same role structure. 3) Select the one that preserves “member(s) ↔ collective” on both sides.Verification / Alternative check:“Hand : Body : Finger” is anatomical part–whole; not a social membership relation. “Leaf : Tree : Root” is also part–whole, not member–group. The ball/bat/pitch set mixes unrelated game elements without a clear collective membership structure.
Why Other Options Are Wrong:They express part–whole or mixed relations rather than membership in a collective.
Common Pitfalls:Confusing anatomical part–whole with social membership hierarchies.
Final Answer:Sister : Family : Brother
