Final answer:
The passage from "A Modest Proposal" serves to highlight the satirical nature of the essay by suggesting a ludicrous solution to poverty, thereby engaging the reader with shock and prompting consideration of deeper social issues.
Step-by-step explanation:
The passage you've referred to is from Jonathan Swift's satirical essay "A Modest Proposal." In this essay, Swift suggests that the impoverished Irish might ease their economic troubles by selling their children as food to rich gentlemen and ladies. By including this passage, which suggests children could be delicious food, Swift makes a proposal so ridiculous that readers will know his essay is a satire. The idea is so preposterous and gruesomely detailed that it contributes to the essay's satirical impact by provoking shock and forcing readers to consider the underlying serious social critique about the mistreatment and disregard for the poor.
