Which detail supports the idea that the farm is a symbol for russia? mrs. jones slips out unseen. moses jumps off his perch. the animals expel jones. the animals race back.

In George Orwell's fairy story "Animal Farm" there is a lot of symbolism. Basing on the question you are being asked, and according to the general spirit or previous knowledge of this novel we can say that the events take place on a farm. In this way, every time Mrs Jones comes to the farm he is expelled by the common action of the animals and thereby suggesting the idea that the farm should be run only by order of other animals. (Animals being lead by a communist model, where the porks are the leaders of a communist party system ).  Mrs Jones can also be seen as a symbol of the capitalist system, based on the way he is portrayed in the novel. The correct answer is c) the animals expel Jones.

C. The animals expel Jones

It just makes sense ¯\_(ツ)_/¯
