Answer:
The phrase "The world was a cattle wagon hermetically sealed" is an example of a simile, which is a type of figurative language that compares two things using "like" or "as". In this case, the world is being compared to a cattle wagon that is hermetically sealed. This comparison emphasizes the idea that the world is a confined and restricted space, much like a cattle wagon, which is used to transport animals in a cramped and uncomfortable manner. The phrase also suggests a sense of isolation and detachment from the outside world, which further reinforces the idea of confinement.
