Hello. You forgot to say that Part A asked what was the central theme of "Shooting an elephant". The central theme is the violence and destruction capacity of British imperialism.

“but in reality I was only an absurd puppet pushed to and fro by the will of those yellow faces behind. I perceived in this moment that when the white man turns tyrant it is his own freedom that he destroys.”

Explanation:

"Shooting an elephant" is a narrative essay written by George Orwell recounting the reports and the internal conflict he went through when he was a police officer from British Raj in colonial Burma. Although Orwell is a representative and promoter of British expansion, he understands that imperialism is a destructive, violent and cruel situation, being able to harm even the imperialists themselves. This is the main theme of the narrative and can be strengthened through the passage: “but in reality I was only an absurd puppet pushed to and fro by the will of those yellow faces behind. I perceived in this moment that when the white man turns tyrant it is his own freedom that he destroys.”
