Read these lines: "Sick as he was, Dave resented being taken out, grunting and growling while the traces were unfastened, and whimpering broken-heartedly when he saw another dog in the position he had held and served so long. For the pride of trace and trail was his, and, sick unto death, he could not bear that another dog should do his work." Why does Dave fight to stay in harness?

1. 1. The quoted lines say the pride of trace and trail was his, which names his reason. 2. 2. They add that even sick unto death he could not bear another dog doing his work. 3. 3. That is exactly the first option, so it restates the stated cause. 4. 4. Soft ground, loneliness and a beating are never given as his motive in these lines. _Source: The Call of the Wild by Jack London (1903)_
