Adapted from White Fang by Jack London

And so it was with White Fang. The man-animals were gods unmistakable and unescapable. As his mother, Kiche, had rendered her allegiance to them at the first cry of her name, so he was beginning to render his allegiance. He gave them the trail as a privilege indubitably theirs: When they walked, he got out of their way; when they called, he came; when they threatened, he cowered down; when they commanded him to go, he went away hurriedly. For behind any wish of theirs was power to enforce that wish, and he understood this, regardless of his natural reluctance.
He belonged to them as all dogs belonged to them—his actions were theirs to command. It came hard, going as it did, counter to much that was strong and dominant in his own nature; and, while he disliked it in the learning of it, unknown to himself he was learning to like it. It was a placing of his destiny in another's hands, a shifting of the responsibilities of existence. This in itself was compensation, for it is always easier to lean upon another than to stand alone and rely on oneself.
But it did not all happen in a day, this giving over of himself, body and soul, to the man-animals. He could not immediately forego his wild heritage and his memories of the Wild. There were days when he crept to the edge of the forest and stood and listened to something calling him far and away. And always he returned, restless and uncomfortable, to whimper softly and wistfully at Kiche's side and to lick her face with eager, questioning tongue. Select the correct answer.
