Hello. Although you have submitted the text, you have not submitted any questions associated with it. This makes it impossible for me to give you an answer. However, I will try to help you by showing you the context and the meaning of this text within the story.
This text is an excerpt from "A Long Way Gone" written by Ishmael Beah, where he recounts the experiences he had when he became a soldier, still a child at the age of 12, in the Sierra Leone War.
The excerpt presented by you shows how much the war and the situation where Beah lived made him mature a lot and at an early age, since from an early age, he understood the concept of death and especially the concept of death of someone dear and loved. He presents the monkey as a representation of the government, blamed for the deaths and the problems that all citizens in the region are facing, for this reason, the government needs to be removed, killed and overthrown, preventing other people from being killed on his behalf.
Citing passages from a text is one way to provide elaboration in an essay.
The reason why this would be your answer is because when you cite your source, it allows to person to go to the source to see more information about the quote you got, and not leave them empty handed. If you didn't cite you source, it would be considered plagiarism, and wouldn't allow the reader to get to know more about the quote and what happens.
At the end of what story? We need the story!
