VOCABULARY — Choose the antonym (opposite in meaning) of the highlighted word. Sentence: “ADVERSITY teaches man to be humble and self-reliant.”

Introduction / Context:“Adversity” denotes hardship, misfortune, or difficult circumstances. The antonym should represent favorable conditions and success.

Given Data / Assumptions:

• Semantic field: life conditions (hardship vs flourishing).
• We need an opposite at the level of circumstances, not emotions or traits.
• Choices include attitude words and one condition word.

Concept / Approach:“Prosperity” is the natural antonym: it implies wealth, success, and favorable outcomes. The other options are unrelated states of mind or interpersonal feelings.

Step-by-Step Solution:1) Define “adversity”: misfortune/hardship.2) Locate opposite condition: “prosperity”.3) Exclude distractors that do not map to condition-level opposites (e.g., “sincerity”, “animosity”, “curiosity”).

Verification / Alternative check:Common collocations contrast “adversity and prosperity,” especially in proverbial statements, confirming the pairing.

Why Other Options Are Wrong:A) “sincerity” — honesty; unrelated.B) “animosity” — hostility; unrelated.C) “curiosity” — desire to know; unrelated.E) Not applicable because a correct antonym exists.

Common Pitfalls:Mistaking positive-sounding words for true antonyms. Polarity alone (positive vs negative) is insufficient; the domain must match.

Final Answer:prosperity
