4. what function do the animal committees have, and what side effect might such "re-education" have?

The Animal Committees described on Chapter III of Animal Farm have the purpose of organizing the animals into different functions. There are committees such as the Egg Production Committee for the hens, the Clean Tails League for the cows and the Wild Comrades' Reeducation Committee, to tame the rats and rabbits.

These initiatives were not successful, because the animals were behaving almost the same as before. The side effect of this reeducation was that when the animals were being treated with generosity, they took advantage of it. For example, the cat was trying to instruct some sparrows to perch on her paw for her own benefit after attending the Reeducation Committee.
