Fill in the blank with the antonym, in context, of the capitalized word in the…

An antonym-in-context question asks for a word that is directly opposite in meaning to the capitalized word, chosen so the completed sentence still reads as a coherent, well-known statement (often a contrastive maxim).

The capitalized word here is PEACE. The sentence frame "If you wish for PEACE, be prepared for ____." echoes the classic English maxim "If you want peace, prepare for war" (from the Latin adage Si vis pacem, para bellum), which argues that readiness for conflict is what preserves calm. "Peace" denotes a state of calm and the absence of conflict; its direct antonym is "war", a state of armed conflict and hostility. So the blank is completed by "War".

Checking the other options against this contrast confirms the choice:

• Misery is the antonym of "happiness", describing emotional suffering — it does not name a state of armed conflict, so it does not complete the "peace vs. ____" maxim.

• Happiness sits on the same side as "peace" (a positive, calm state); it cannot be the antonym of "peace" itself.

• Healthy describes physical well-being and has no direct semantic opposition to "peace", so it does not fit the sentence's contrast.

Hence the completed sentence reads: "If you wish for PEACE, be prepared for WAR."
