Choose the pair that best expresses the same relationship as:SENTINEL : WATCH
Show Hint
When two nouns appear (e.g., \textit{sentinel : watch}), check if the second is a \textbf{duty/purpose}. Prefer choices where the second word states the agent’s \textbf{function}, not a tool or an occasional event.
Step 1: Interpret the stem
A sentinel is one who keeps watch/guards. Relation: agent (person) \(\Rightarrow\) core duty/purpose (verb)}. Step 2: Evaluate options
(a) Artist : Paint — Agent \(\Rightarrow\) action, but “paint” is the medium/action} of creating art; not a core protective duty} like “watch.” Partially similar but weaker fit.
(b) Soldier : Battle — Agent \(\Rightarrow\) event/occasion; “battle” is not the soldier’s constant duty} but an occurrence. Relation drifts from purpose.
(c) Guard : Protect — Agent \(\Rightarrow\) core duty/purpose}. This exactly parallels sentinel : watch. \(\Rightarrow\) Best fit.
(d) None of these — Not applicable since (c) fits perfectly. Step 3: Conclusion
Option (c) mirrors the agent \(\Rightarrow\) essential duty} relation exactly.
\[
\boxed{\text{Answer = (c) Guard : Protect}}
\]
