Analogy — “Chair : Wood :: ?”. Choose the pair that mirrors an object and the primary material it is commonly made from.

Introduction / Context:An analogy compares relationships. In “Chair : Wood,” the first item is an everyday object and the second is the typical material from which that object is made. To solve the analogy, we must find another pair that preserves this “object → material” relation rather than a “container → content,” “tool → action,” or any other mismatch.

Given Data / Assumptions:

• “Chair : Wood” encodes object-to-material (chairs are commonly made of wood).
• Exactly one option must map a common object to its characteristic material.
• Distractors may look plausible but represent different relations (e.g., content, usage, or storage).

Concept / Approach:Identify which option expresses the same structural relation. We test each choice to see whether the second term is the basic substance used to make the first, in the most common, textbook sense.

Step-by-Step Solution:

Verification / Alternative check:“Mirror : Glass” satisfies the precise parallel to “Chair : Wood.” Although bottles can be glass or plastic, mirrors are classically glass-based, reinforcing the intended relation more consistently.

Why Other Options Are Wrong:

Common Pitfalls:Confusing content or process with material; choosing a pair that fits loosely rather than the clearest, standard mapping.

Final Answer:Mirror : Glass
