What is a gyre? how does that word relate to some other word in the poem? what does the wording "blood-dimmed tide" remind you of?

After reading it a few times, I am almost certain that the answer is B.

"The animals on the farm will die as a result of human actions."

Major tells the animals that if Man tells them that they have their best interests at heart, they are lying. Man only does things that benefit only themselves and no one else.

Hope this helps!!
