Which of the following does not illustrate the competing influences of civilization and savagery on Jack?
"He noticed blood on his hands and grimaced distastefully, looked for something on which to clean them, then wiped them on his shorts and laughed."
"'I cut the pig's throat,' said Jack, proudly, and yet twitched as he said it. 'Can I borrow yours, Ralph, to make a nick in the hilt?'"
"'There was lashings of blood,' said Jack, laughing and shuddering, 'you should have seen it!'"
"His mind was crowded with memories; memories of the knowledge that had come to them when they closed in on the struggling pig, knowledge that they had outwitted a living thing, imposed their will upon it, taken away its life like a long satisfying drink."
