The answer is A. The Russian revolution. The whole book is about it. Each of the animals represents an important person from that time.
This scene occurs when Balfour is on the small islet. Balfour gives into despair when he tires to cross the river but cannot -- it is too deep. He finds that his "yard" (a piece of wood he was saving to float on) has been carried away. Believing he has no way to escape the islet, he gives into despair and weeps.
The people in power is the answer hope this helps :-D
