Classification (antonyms): Three pairs are true opposites; one pair is actually a synonym pair. Identify the non-antonym pair among the following.

Introduction / Context:
Antonym classification questions require you to separate true opposites from words that are similar or only loosely related. In the given set, three pairs express direct oppositions along a single semantic axis, while one pair expresses near synonymy rather than opposition. The task is to find the exception that does not provide an opposite meaning relationship.

Given Data / Assumptions:

• Pairs to examine: Dim : Bright, Wrong : Right, Shallow : Deep, Genuine : Real.
• We define antonyms as words that stand at opposite ends of the same scale or concept (for example, light vs dark, correct vs incorrect).
• We define synonyms as words that share similar meanings (for example, authentic and real).

Concept / Approach:
The approach is to test each pair for a strict binary contrast along one dimension. If both words are commonly used as mutually exclusive alternatives in ordinary usage, the pair is a true antonym pair. If they can substitute for each other in typical contexts without flipping meaning, they are synonyms and therefore the odd pair in an antonym set.

Step-by-Step Solution:

Verification / Alternative check:
Attempt substitution in sentences. Replace genuine with real in “This is a genuine diamond.” The sentence “This is a real diamond” preserves the intended meaning, which confirms similarity, not opposition.

Why Other Options Are Wrong:

Common Pitfalls:
A frequent mistake is to assume that two words with overlapping connotations are antonyms. Synonyms like genuine and real cannot be opposites because they do not define a two sided scale. Another pitfall is to judge based on tone rather than meaning. Always check whether replacing one with the other reverses meaning or preserves it.

Final Answer:
Genuine : Real
