1) the animals revolution its technicaly impossible, but if you compare it with a normal revolution, it's the same than any other revolution, They wasn't agree with the rules and conditions they were living so they had to do something, I'm agree with it.
2) yes, because the animals where fighting for something they really need, and for real rights, and all people would want the same
3) Old nature gives the idea of the revolution, all animals accept it and they take the farm by strength . They reveal human characteristics as the pigs that started getting all the power, using clothes, drinking. First, the humans where considered as the enemy for being mean with them and later the pigs "adopt" all these human characteristics.
4) Pigs earn the rights to the cows milk by using the power of words, using TV and like for being the leaders of the revolution and most intelligent ones. This part shows that pigs went stronger than other animals and the rest like the followers.
5) Snowball should never been kicked out the farm, he was sort of the "good guy" that would've make the farm work better and would take the farm to a "new era" of happiness.
6) 1.- Creating rules that doesnt affect or get applied to him
2.- making the animals believe that he was the "good guy" and someone that would help them
3.- As pigs were the most intelligent animals, he make the other animals think that his opossition (snowball) is bad, that the only way of "winning" is taking him as a leader.
The decition taking changes a lot, first more like a common decition and with napoleon's dictatorship, a monarchy, only one chooses.
7) The animals get executed because they were against Napoleon's rules and thoughts. This is a message to the animals saying like: "if you are not agree with me, you will die"
8) It is fair, as they are more intelligent they can make better decitions.
In my family the my parents make the decitions but they ask us first if it concern us. And in a nation aspect is simmilar, president and ministers.
9) The power makes people change, they forget where they startend, why they started the revolution and "who they really are"
10) The pigs were way more intelligent than the other animals, they noticed that this "crowd of animals" was in need of a leader, they had their chance and they took it. Qualities of conviction allowed them to rule the animals.
Example: They say that if they are not the leaders, the farmer will come back to the farm.
