(Animal farm) In the space below, write an explanatory essay of at least 500 words. Discuss how your chosen characters and their actions express and develop the two themes you've selected. Use details from the story and information about historical events to support your ideas

The prompt is "major characters in novels or plays often encounter moral, physical or psychological dangers or choices.  The ways in which the characters respond to these situations frequently reveal the authors' meaning. Analyze how the dangers or choices characters have to make are used by authors to develop their themes."  I doubt that it can be applied to Animal Farm exactly. At least you will get the idea how the author chose the characters. As the back-up, you may turn for the help to the guys I personally know. Check PrimeWritings site for more details.
