Answer:
The correct answer is number 4. Swift writes that "poorer tenants will have something valuable of their own" that can "help to pay their landlord's rent."
Explanation:
We must use quotation marks to include portions of text that were written by another author. Notice that if we paraphrase - as done in number 2 -, there is no need for quotation marks.
Number 1 is incorrect because the quotation marks are not distinguishing the texts as they should. They are including both this author's and Swift's words. Number 3 is also wrong because it is basically a paraphrase. There is no need to use quotation marks to include only "their corn and cattle". That portion is not enough to demand the marks.
Number 4 is the correct one. It uses quotation to make it clear that the author is repeating Swift's words by separating them from his/her own.
