What is the purpose of the bill of rights? to what part of the preamble is it most directly related?

The American Bill of Rights is the set of the first 10 amendments to the US Constitution, these guarantee freedom of expression, religion, the press, the right to assembly, the right to file lawsuits with the government and various individual rights on procedural aspects and criminal proceedings. They were proposed by Congress and ratified by the different states, in compliance with the fifth article of the original Constitution.

This bill of rights is directly related to the Preamble of the Constitution, since this text grants all the benefits of "freedom" for the people and for future residents, thus granting them the civil rights mentioned above.

in this passage from chapter 6 of "animal farm", by george orwell, what the author is ridiculing in this passage is the frivolity of some rules.

clover, the mare, believes she remembers that the fourth commandment forbade sleeping in beds because it was something that humans did. snowball, napoleon, and the pigs are brain-workers who look after the welfare of the farm. they are the obvious leaders because they are smart, and so they are entitled to eat the best food and sleep in beds. it is squealer, who says these lines making the difference between sleeping with sheets, what humans do, and sleeping in beds, what pigs do. the unwillingness to question authority makes the oppressed to obey without thinking.
