Answer:
Dear mum,
It's been so long, and my feet are tired. These filthy rebellious pigs think they can win their independence, and I find that rather hilarious. Their tactics are unorthodox and these battles get very messy. Oh dear, this war is absolutely horrid, I long for some freshly brewed tea. These inexperienced marksmen taking part of such a pitiful militia have to stand in the kings way along with these savages they teamed up with, absolutely distasteful. Me and my brothers shall advance and restore order for Great Britain.
Love,
Tom
A predicate nominative because "one" follows the verb "to be- was (past tense). A predicative nominative alwasys follows the verb to be in al of its forms and one should view it as "equals", as in, Langston Hughes equals on of the greatest poets of the Harlem Renaissance. A predicative adjective must modify the subject and is linked with a verb, but in this sentence "one" does not modify Hughes. Another trick for remembering is that if you were to switch the order of the sentence, it would still make sense; "One of the greatest poets of the Harlem Renaissance is Langston Hughes."
What he suspects about a person who drives a yellow car, is that perhaps the driver is the murderer of his wife, since she was killed by a person driving a yellow car, and is the car that Tom was driving.
The commandment "All animals are equal" is not being followed in the first five chapters of the novel. One example is that Napoleon was treated better than all the other animals and constantly mistreated everyone. Another example is that the pigs relaxed and did nothing all day while the other animals had to work. The pigs were treated like royalty in comparison to the other animals.
