Answer:
the utter absurdity of his plan
Explanation:
Satire is the use of humor, irony, exaggeration, or ridicule to expose and criticize people's stupidity or vices.
Jonathan Swift uses satire in his book A Modest Proposal to ridicule and mock the \British elites for their treatment of the Irish people by suggesting that selling off children would ease their economic troubles.
He uses satire throughout the essay to show the impracticability of the British policy that is supposed to remedy the sufferings of the Irish.
From the excerpt, Swift is showing the utter absurdity of the plan of using carcass to make dresses, gloves and boots.
