What are the rising action, falling action, and resolution in Animal Farm by George Orwell?

In the opening chapters of Animal Farm, the animals rebel against the cruel leadership of the farmer and take over the farm themselves. The pigs establish themselves as the leaders, and one pig named Napoleon has a desire to be the most powerful, so he drives out his only competitor named Snowball. The rising action in the book is when Napoleon closes the meetings, forces other animals to sit out and holds meetings with only the other pigs. This group of pigs becomes the force that runs the entire farm. Another part of the rising action portrays how Napoleon becomes anxious and paranoid that another animal will try to take his place. The climax of the story occurs when Napoleon claims that Snowball is responsible for problems on the farm and accuses other animals of being in contact with him. He uses this as an excuse to force animals off the farm and uses dogs to attack them. The falling action is a time of great trials for the animals. They are all very unhappy and it is obvious that the doctrines of the farm have been altered and that the wellbeing of the animals is no longer the most important aspect. The resolution of the story does not seem like much of a resolution because it is not a happy ending. There is no equality between the animals, and the pigs begin to walk on their hind legs, resembling humans and acquiring many human characteristics. The animals can no longer distinguish between pigs and people.
