Explanation: one of the notable difference between the people of houyhnhnms and England is the significance of horses. It was said that in the land of the Houyhnhnms the behavior of these animals was rational and orderly, acute and judicious. It was the horses that deliver Gulliver from the Yahoos although not by any physical action but by just appearing on the road.
Horses are in charge in Houyhnhnms which is different from England, Gulliver will try with admirable determination to change himself into a more horse-like state, but he will fail.
