Students in Mrs. Carr’s class are asked to make a prediction after reading this passage from White Fang.

But the bane of his life was Lip-lip. Larger, older, and stronger, Lip-lip had selected White Fang for his special object of persecution. White Fang fought willingly enough, but he was outclassed. His enemy was too big. Lip-lip became a nightmare to him. Whenever he ventured away from his mother, the bully was sure to appear.

Which student prediction is most reasonable?
