Answer:
B. Most rich landlords would make far better eating than any other form of food.
Explanation:
The last paragraph of Jonathan Swift's (1667–1745) "Modest Proposal - For preventing the children of poor people in Ireland" (1729) is;
"I profess in the sincerity of my heart, that I have not the least personal interest in endeavouring to promote this necessary work, having no other motive than the publick good of my country, by advancing our trade, providing for infants, relieving the poor, and giving some pleasure to the rich. I have no children, by which I can propose to get a single penny; the youngest being nine years old, and my wife past child-bearing."
The main idea and conclusion of this paragraph is that people should believe in Swift's sincerity because he has nothing personal to gain from these steps to eliminate poverty. However, this option is not provided, so we should try to find out the second best option, which is option B. Swift also suggests that these steps (selling infants as food a for cannibals), would do public good by providing infants (as food) to the rich. The rich would be pleased to have such a food. So, based on these observations, the best option (of the provided ones) is option B.
