Answer:
The detail from the text that best shows a parallel to authoritarian governments is the abolishment of a song from the rebellion.
Step-by-step explanation:
The detail that best shows a parallel to authoritarian governments is the abolishment of a song from the rebellion. This is because in many authoritarian governments, the ruling regime seeks to control what people can and cannot say, write, or sing. The abolishment of "Beasts of England" demonstrates the leadership's desire to control the narrative and prevent any expression of dissent or criticism of the regime. Additionally, the justification for abolishing the song, that it is no longer needed because the society has already been established, is reminiscent of the rhetoric used by authoritarian leaders to justify the suppression of free speech and dissent, often claiming that such actions are necessary for the greater good or to maintain stability.
