Analogy — Match the relation type: Capricious : Reliability

Introduction / Context:
“Capricious” means unpredictable or impulsive; “reliability” entails steadiness and predictability. The stem shows semantic tension: a concept that conflicts with predictability. We need a pair with the same incompatibility.

Given Data / Assumptions:

• Capricious ↔ Reliability: unpredictability undermines reliability.
• We look for a similar “spontaneous vs predictable” clash.

Concept / Approach:
Reject pairs that are synonyms, unrelated, or mismatched categories; prefer a pair where the first term inherently resists the second.

Step-by-Step Solution:
(a) Extemporaneous : Predictability → extemporaneous implies spontaneous/unscripted; clashes with predictability (good match).(b) Unreliable : Inhuman → different axes (dependability vs humanity) — unrelated.(c) Tenacious : Practicality → perseverance vs practicality; not inherently opposed.(d) Arbitrary : Whimsical → near-synonyms; not a conflict pair.

Verification / Alternative check:
The semantic incompatibility in (a) mirrors the stem’s unpredictability vs predictability.

Why Other Options Are Wrong:
(b) Orthogonal notions; (c) not opposites; (d) synonyms rather than tension.

Common Pitfalls:
Picking synonyms (d) because they “sound close,” while the stem expresses opposition, not equivalence.

Final Answer:
Extemporaneous : Predictability
