Analogy — Map phenomenon to its typical condition: Thunder : Rain :: Night : ?

Introduction / Context:
“Thunder : Rain” associates a phenomenon with a typical condition that accompanies it (thunder commonly co-occurs with rainfall in storms). We seek the parallel typical condition for “night.”

Given Data / Assumptions:

• Thunder often appears with rain/thunderstorms; they are frequently linked conditions.
• Night is typically characterized by darkness.
• We are mapping phenomenon → characteristic condition.

Concept / Approach:
Prefer the general, definitional attribute rather than a time label or near-synonym of time of day. For night, “dark” is the canonical condition.

Step-by-Step Solution:
Thunder → rain (frequent accompaniment).Night → ? → dark (defining condition).

Verification / Alternative check:
Although thunder can occur without rain nearby (e.g., dry thunder), the standard aptitude mapping treats “thunder–rain” and “night–dark” as widely taught associations.

Why Other Options Are Wrong:
(a) Evening/d) Dusk – specific times, not the defining condition.
(c) Day – opposite of night.

Common Pitfalls:
Overcomplicating with meteorological exceptions; analogy exams use the conventional pairing.

Final Answer:
Dark
