To support the theme "loyalty is a powerful force with which to be reckoned" in part 5 of The Call of the Wild, the following three sentences would be effective:
- "Buck knew no greater joy than that rough embrace and the sound of murmured oaths, and at each jerk back and forth it seemed that his heart would be shaken out of his body so great was its ecstasy."
- "For a long time after his rescue, Buck did not like Thornton to get out of his sight."
- "Because of his very great love, he could not steal from this man, but from any other man, in any other camp, he did not hesitate an instant; while the cunning with which he stole enabled him to escape detection."
These sentences illustrate Buck's deep loyalty and attachment to John Thornton, emphasizing how this loyalty influences his behavior and emotional state.
