From what i can tell the answer would be D.
Adam has spent most of his time thinking he is the only one on earth, he hasnt ever seen anyone, or known who his family was until he got a knock on his door “huh? Adam said. He’s never heard a knock in his life. He looked out his window and saw a strange boy. “Whats that? Thing?” Adam said he opened the door and the kid had dark grimmy eyes, almost staring into his soul. Adam faintly looked around and said “um, can i help you?” The boy said nothing just staring at him, then he ran away. “Wait!” Adam said “come back!” He tried to chase the boy but he was to fast. Out of breath he said “How...how did he run so fast?” Adam looked at the floor and he noticed he dropped something. To his surprise the handwriting was nice and neat. It said a dark and creepy message. “Nothing lasts forever, especially you.”
"Beasts of England", the original anthem of the Animal farm corresponds to the famous socialist anthem, The Internationale, but also alludes to Shelley's Men of England. In the book, the pig Old Major explains his dream of an animal-controlled society three nights before his death.....The animals sing "Beasts of England" frequently after the rebellion, especially after meetings. At one point when Clover the horse questions the direction of Animal Farm, she sings "Beasts of England" which causes the other animals to join in......After "Beasts of England" has been used to express criticism of the direction of Animal Farm, Napoleon tries to supplant the song, arguing that such an anthem is antiquated and no longer needed after the rebellion has been completed. The anthem is first replaced by the short "Animal Farm!" and later by "Comrade Napoleon", while "Beasts of England" is eventually outlawed. The phasing out of "Beasts of England" as the anthem of Animal Farm corresponds to the Soviet Union's 1944 replacement of The Internationale with the National Anthem of the Soviet Union.
