Map each adjective to its nearest plain-English synonym: “Indefatigable” most nearly means “tireless”. “Inveterate” most nearly means which of the following?

Introduction / Context:
This analogy checks synonym control. “Indefatigable” translates to “tireless.” The second word, “inveterate,” describes a habit that is deep-seated, persistent, or habitual. Therefore the parallel pair should be “tireless : habitual.”

Given Data / Assumptions:

• Indefatigable = incapable of being fatigued, i.e., tireless.
• Inveterate = firmly established by long persistence, i.e., habitual.
• We seek a mapping where both members are replaced by their simplest accurate synonyms.

Concept / Approach:
Because the first mapping is provided (indefatigable → tireless), we mirror the structure with the second (inveterate → habitual). Any option that breaks the synonymy or reverses polarity should be discarded.

Step-by-Step Solution:

Verification / Alternative check:
Both conversions are standard dictionary glosses; the mapping is widely accepted in vocabulary drills.

Why Other Options Are Wrong:

• Tireless : Tired — antonyms; breaks synonym pattern.
• Tired : Habitual — mixes an antonym with a synonym; inconsistent.
• Impoverished : Habitual — unrelated meanings.
• Tireless : Occasional — “occasional” opposes “habitual,” breaking structure.

Common Pitfalls:
Mistaking “inveterate” for “old/ancient” instead of “habitual.”

Final Answer:
Tireless : Habitual
