Cannot be taken literally and must be understood as a whole.

Idiom is the correct answer.

Explanation:

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.

the correct answer is "the rhythm and rhyme scheme add to an eerie and suspenseful tone". poetry is literature written in stanzas and lines that use rhythm to express feelings and ideas. poets will pay particular attention to the length, placement, and grouping of lines and stanzas. this is called form. lines or whole stanzas can be rearranged in order to create a specific effect on the reader.
