Final answer:
Ralph cries at the end of 'Lord of the Flies' for the 'end of innocence' and the 'darkness of man's heart', as well as mourning the death of Piggy.
Step-by-step explanation:
The student is asking about the reason for Ralph's crying at the end of the novel, 'Lord of the Flies', by William Golding. At the end of the book, Ralph cries for the 'end of innocence' and the 'darkness of man's heart', as well as for the 'fall through the air of his true, wise friend', Piggy. These tears represent the falling action of the story, where Ralph is reflecting on the events that unfolded and the loss of innocence experienced by all the boys on the island.
Thus, the correct answer is 'e. Both B and C', suggesting that Ralph's tears are for the loss of innocence and the inherent evil within humanity, as well as the loss of Piggy. The emotional climax of suffering and personal reflection is what leads Ralph to this point of grief and revelation.
