How and why dickinson's "because i could not stop for death" is structured as an arc.

  i understand the caesura (plural for caesura) as decelerating down its pace, which makes intellect seeing the speaker's privilege that, when death came to accumulate her, "he knew no haste."   first, they initiative near the school to watch the children play, then to the fields to lookout the sun set over the scrap.   she describes the way night seems to fall after the sun has passed them, and how she grows chilly.   finally, death's carriage reaches at the speaker's grave "in the ground," and she designates how corporeal time is moving so swiftly while time for her moves so slowly because she is measuring it against "infinity."   therefore, dickinson's use of caesura really slows the pace because the reader must pause so often, at least every time she employs an end dash, and this is appropriate to the content of the text

to inform readers about the ways young people improve the world.

"a" because he is appealing to logic as oppose to appealing to the audience's emotions.
