C.It pokes fun at the professed selflessness of people who propose
solutions to society's problems.
Explanation:
One of the proposal described just before this concluding excerpt is selling the poor Irish one year old children to abroad as a source of food. According to the proposer (a narrator and not Jonathan Swift himself), this selling will make Irish people rich. After this proposal the narrator wants to convince readers of his selflessness. This is very satiric and satirizes the professed selflessness of such proposers. The proposer is wanting himself to be believed very sincere after saying that he can not sell his own children, because they are old.
Option A, B and D are not correct. Firstly because the proposal is a satire and the proposer is not Jonathan Swift himself, but just a narrator - a satirized self professed selfless proposer. Secondly as this proposal is a satire, there is no mention of satirizing or poking fun in any of these options.
An adjective and adverb phrase differ in that an adverb modifies verbs, adjectives, and other adverbs. To help remember the difference, the word itself has “verb” inside it, and adverbs tend to end in “-ly.” “Slowly,” “loudly,” and “happily” are all adverbs.
