In my opinion, the sentences that correctly use quotations are:
<span>2) Swift asserts that whoever finds “a fair, cheap and easy method” for solving the overwhelming issue of poverty in England would deserve to have “his statue set up for a preserver of the nation.” The author quotes chosen parts of Swift's narrative with correct punctuation.
</span><span>4) Swift explains that his proposal would bring relief to impoverished parents because they would “be rid of the charge of maintaining them after the first year.” The author quotes a part of the narrative.
5) “This would be a great inducement to marriage, which all wise nations have either encouraged by rewards, or enforced by laws and penalties,” writes Swift about his proposal. The author quotes an entire sentence as direct speech. </span> The first example isn't correct because the whole sentence is in quotation marks. The third one isn't correct either because there is no quotation; it is just a paraphrase.
