Analogy — Choose the closest verb synonym: Safe : Secure :: Protect : ?

Introduction / Context:
This analogy pairs near-synonyms across part of speech. “Safe : Secure” connects adjective synonyms. We must find the verb that most directly aligns with “protect.”

Given Data / Assumptions:

• “Protect” is a verb meaning to keep safe from harm.
• “Guard” is the closest verb synonym among the choices.
• “Conserve” focuses on saving resources; “Lock” is a method, not a synonym; “Sure” is an adjective, not a verb.

Concept / Approach:
Preserve part of speech (verb) and semantic field (defense/safety). Choose the lexical item that can typically substitute for “protect” without altering intent.

Step-by-Step Solution:
Safe ↔ secure (adjective synonyms).Protect ↔ ? (verb synonym) → guard.Hence: Protect : Guard.

Verification / Alternative check:
Paraphrase test: “guards the data” ≈ “protects the data.” Meanwhile “locks the data” is metaphorical and narrower; “conserves the data” shifts to preservation/efficiency.

Why Other Options Are Wrong:
(a) Conserve – resource-saving, not defense.
(b) Sure – part of speech mismatch and meaning mismatch.
(d) Lock – a method/tool, not a general synonym.

Common Pitfalls:
Choosing a related action (“lock”) instead of a true synonym; analogy hinges on equivalence, not mere association.

Final Answer:
Guard
