Answer:
All the men gathered around the great oak because it served as a symbol of Ilium Works and they did it in order to sing the anthem entitled, "Love's Sweet Song."
Step-by-step explanation:
The question is related to the novel entitled, "Player Piano," which was written by Kurt Vonnegut. It centers on the story of a futuristic society where widespread mechanization flourished.
Ilium Works is a company which owns a green island called "The Meadows,." This served as a location for company retreats. In the island is an oak tree, which is said to be a classical symbol of Golden Age.
However, the oak is also a symbol of the company. The purpose of the company retreat is to allow the people to get back to nature. However, this sounds ironic because it contradicts the order of company loyalty in Ilium Works.
