Explanation
Correct answer: C.
Choice C is the best answer because it would most directly support the student’s claim about the motivation for including explanatory notes with the stand-alone volume of the poem. The text explains that the poem had previously been published without the notes in a quarterly journal. It stands to reason that readers who had purchased the journal issue containing the poem would be unlikely to purchase an unchanged version of the poem in a stand-alone volume. However, the inclusion of notes in that volume would encourage the purchase of a stand-alone volume, since the later text would differ from the original by including the author’s own explanation of the poem. Therefore, if it were true that the publishers of the stand-alone volume had requested the notes to make the book attractive to readers who already had a copy of the journal issue, this fact would support the student’s claim that the notes were included primarily as a marketing device.
Why the other choices are wrong
Choice A
Choice A is incorrect because the student’s claim is about the motivation for including the explanatory notes in the stand-alone volume, not about changes that might have been made to the poem itself for publication in that volume; moreover, the text never suggests that such changes were made.
Choice B
Choice B is incorrect because the student’s claim is about why the explanatory notes were included in the stand-alone volume, not about how the notes affected readers’ and critics’ subsequent experience of the poem.
Choice D
Choice D is incorrect because the fact that the poet drafted multiple versions of the explanatory notes doesn’t directly address the issue of whether the notes were intended as a marketing device, as the student claims; the correspondence would support this claim only if it showed that the poet had revised the notes specifically to make them useful to the marketing of the stand-alone volume.
