Analogy — Attribute to object: Round : Earth :: ? : ? Choose the pair that mirrors “shape/property : object”, just like “Round : Earth”.

Introduction / Context:Analogy questions often encode a precise semantic relation. In “Round : Earth”, “Round” is an attribute (shape) and “Earth” is the object that possesses that attribute. We must select a pair with the same “attribute → object” relationship, not “object → attribute” reversed, nor “part → whole”.

Given Data / Assumptions:

• “Round” labels a shape; “Earth” is the entity described.
• Options mix attributes (Thin, Transparent), measures (Height), and objects (Paper, Gas, Dice).
• The best answer will preserve part-of-speech and role symmetry: adjective/noun (shape/property) → noun (object).

Concept / Approach:The key is functional parallelism. “Round : Earth” is “shape : thing”. Among choices, “Cube : Dice” presents “shape : object typically having that shape.” It mirrors the relation exactly, unlike pairs where the right term is not an object (e.g., “Height” is not an attribute applied to “Mountain” in the same grammatical way; it is a measure dimension of the mountain).

Step-by-Step Solution:

Verification / Alternative check:Substitute: “Round describes Earth” vs “Cube describes Dice.” Both read as “attribute applies to object.”

Why Other Options Are Wrong:

• Thin : Paper — plausible attribute, but paper is not necessarily thin by definition; also less canonical than “dice are cube-shaped”.
• Height : Mountain — “Height” is a measure, not a describing adjective like “high”; relation type differs.
• Transparent : Gas — not all gases are transparent by necessity; weaker conventional pairing.
• None of these — incorrect since a valid pair exists.

Common Pitfalls:Accepting any adjective–noun pair without checking whether the attribute is a defining/typical descriptor of the object (as “cube” is for “dice”).

Final Answer:Cube : Dice
