Final answer:
Jack and Ralph represent the world of civilization and savagery in the novel 'Lord of the Flies,' showing the tension between structured society and primal instincts.
Step-by-step explanation:
The narrator suggests that Jack and Ralph depict the world of civilization and savagery, meaning the correct answer is C) The world of civilization and savagery. This dichotomy is central to the themes of William Golding's novel Lord of the Flies, where civilization represents the ordered, structured society from which the boys have come, and savagery represents the primal, brutish behaviors that emerge as they are isolated from that society on the island. Ralph is often associated with the attempts at keeping order and representing the vestiges of civilization, while Jack succumbs to and embodies the savage instincts that the absence of society allows to surface.
