Read these lines: "Buck made no effort. He lay quietly where he had fallen. The lash bit into him again and again, but he neither whined nor struggled. Like his mates, he was barely able to get up, but, unlike them, he had made up his mind not to get up. He had a vague feeling of impending doom." Why does Buck stay down?

1. 1. The quoted lines set his mates beside him: they are barely able to rise, and so is he. 2. 2. The word unlike then separates him from them, because he had made up his mind not to rise. 3. 3. A vague feeling of impending doom is given straight afterwards as what lies behind that decision. 4. 4. Confusion, a tangled harness and waiting for the others are all absent from the lines. _Source: The Call of the Wild by Jack London (1903)_
