Where did Jack London come up with the ideas
for many of his stories?

This was the Alaska Gold Rush. Although London never found any gold, his experience in the extreme environment of this cold part of the world gave him ideas for the stories he would write when he decided to return to California. Upon his return to the San Francisco area, he began to write about his experiences.

normally working animals are domesticated and ruled by a master, a domesticator (tamer), to perform basic and important functions on a farm, for example. the value used in this context is animal labor in exchange for food. it is not so much a contrast to the story told by napoleon and the pigs, since the animals of that particular farm also performed functions on the farm through domestication. the only thing is that in this case, who rules them is a pig, also an animal, but very respected, to whom the other animals lent him submission. that's about a strong relationship of dependency between animal and owner.

they used personification to make the truck seem mean and violent.

hope this !
