Read this excerpt from White Fang.

[White Fang] felt a vacancy in him, a need for the hush and quietude of the stream and the cave in the cliff. Life had become too populous. There were so many of the man-animals, men, women, and children, all making noises and irritations. And there were the dogs, ever squabbling and bickering, bursting into uproars and creating confusions. The restful loneliness of the only life he had known was gone. Here the very air was palpitant with life. It hummed and buzzed unceasingly.

How does White Fang change when he compares his new environment to his old environment?

He appreciates that he is no longer lonely.
He misses the peace of the wild.
He develops a fear of the wild.
He decides to become a loyal pack dog.
