Because people feel the need to continue acquiring more things that they do not need but want without realizing
The correct answer is: A. Sooner or later we must all accept our obligation to future generations.
A persuasive essay is an essay that aims to convince the reader of a certain point of view and its superiority over opposing points of view. In the sentence, "Sooner or later we must all accept our obligation to future generations", the author is summing up his argument and persuading the readers to accept their "...obligation to future generations". Option B, C and D are not conclusions to a persuasive essay because they either state personal opinions or contain subjective claims.
Answer: I would contend that the right answer is the E) "... since they provide fascinating evidence about the creative processes in which this great Modernist engaged."
Explanation: Just to elaborate a little bit on the answer, it can be added that the other options feature sentences that end with a preposition ("engaged in"), and although this is permissible in the English language, it is not the most formal option. In the example, a good way to correct it is to replace it by "in which." I would suggest changing the sentence so it reads "Although the author himself declared them unpublishable, the first appearance in print of 40 poems by T.S. Eliot is a significant event, since they provide fascinating evidence about the creative processes in which this great Modernist engaged."
