Explanation:
The correct answer is To make peace because this idiomatic phrase is used globally to describe the act of resolving an argument and ending a conflict.
Historical Origin: The expression comes from an ancient Native American diplomatic custom where warring tribes would literally bury their weapons, such as tomahawks or hatchets, deep underground to signal the official conclusion of hostilities.
Metaphorical Meaning: In modern English, the phrase serves as a common metaphor for forgiving past grievances, putting aside personal arguments, and restoring a harmonious relationship.
Incorrect Options:
To start a war is incorrect because it describes the exact opposite behavior, which is traditionally represented by the idiom 'to pick up the hatchet'.
To hide something is incorrect because while burying involves concealing an object underground, the idiom's true meaning centers on reconciliation rather than hiding general items or secrets.
To dig is incorrect because it reduces a deeply established figurative idiom down to a basic, literal physical action, completely missing the intended cultural meaning of the phrase.
