Complete the analogy: “A : Roots :: House : B”. Choose A and B so that each second term denotes the essential supporting/base part of the first.

Introduction / Context:This analogy pairs an object with its essential supporting base. For a living plant, roots provide anchorage and uptake; for a house, the foundation provides structural support.

Given Data / Assumptions:

• Roots are the supporting/anchoring part of a tree (plant).
• Foundations are the supporting/anchoring part of a house.
• We must keep relation symmetry “whole : base.”

Concept / Approach:The relation is “entity : foundational support.” Hence, A should be “Tree” and B should be “Foundation.”

Step-by-Step Solution:1) Decode the first pair type: whole : base (tree : roots).2) Apply to the second: house : foundation.3) Select the option that preserves this mapping exactly.

Verification / Alternative check:Other house parts (walls, floor, roof) are structural but not the foundational base that transmits load to the ground; “foundation” is the true counterpart to “roots.”

Why Other Options Are Wrong:

• Branches/Walls: Not base components.
• Trunk/Floor: Trunk is main stem, not base; floor is not the foundational base.
• Flower/Walls: Decorative/reproductive vs. enclosure; mismatch.
• Leaf/Roof: Functional/covering, not base.

Common Pitfalls:Confusing “important part” with “base.” Only “roots” and “foundation” truly serve as foundational supports.

Final Answer:A. Tree, B. Foundation
