Analogy — Select the pair with the same opposite-of-error relation: Error : Infallible :: ?

Introduction / Context:“Infallible” means incapable of making an error. The pair “Error : Infallible” therefore encodes a concept and an adjective that denotes the absence of that concept. We must find a parallel pair where the second word names an absence-of property for the first word (or its domain), just as “impeccable” means without flaw or error.

Given Data / Assumptions:

• Error ↔ infallible (no errors).
• Target is a similar opposition: presence of a defect vs an adjective meaning free from such defects.

Concept / Approach:Look for an adjective that literally encodes flawlessness in ordinary usage, creating the same antonymic or negation relation found in the model pair.

Step-by-Step Solution:

Verification / Alternative check:Dictionary sense confirms “impeccable” as “faultless; without flaws.” Thus, “Flaw : Impeccable” cleanly parallels “Error : Infallible.”

Why Other Options Are Wrong:

• Emotion : Invulnerable — mismatched semantic fields.
• Defect : Intolerable — focuses on tolerability, not perfection.
• Cure : Irreversible — unrelated categories.
• None of these — incorrect as a perfect match exists.

Common Pitfalls:Choosing approximate opposites instead of a precise “absence-of” adjective like impeccable or infallible.

Final Answer:Flaw : Impeccable
