The answer to the five house problem is not so straight forward. The first step to take was to solve the orientation of the houses. The second house to the left was blue, being next to the norwegian on the far left. The norwegian could not be red, that belonging to the englishman. The norwegian could not be ivory, because of it's relative orientation to green, nor could it be green leaving the second house from the left ivory. The norwegian owned the yellow house. The middle house could not be green, for the middle house drank milk, and not coffee, nor could it be ivory, making the second house green, so it was red. The green and ivory fell into place at this point. YELLOW BLUE RED GREEN IVORY Norwegian English Horse Milk Coffee Kools The next step was to resolve who had what cigarettes. The norwegian had the kools, which were in the yellow house, and the japanese had the parliaments. Neither the ukrainian nor the englishman could have the lucky strikes because they had a different drink than orange juice. This meant that the old golds and the chesterfields were mutually inclusive to the ukrainian and the englishman leaving the spaniard having the lucky strikes. The next step was to solve who had what drinks. The ukrainian had the tea, the englishman had the milk, and the spaniard had the orange juice. This meant that the water and coffee were mutually inclusive to the norwegian and the japanese. Since the norwegian's house was yellow, he could not have the coffee. Therefore, the japanese had the coffee and the NORWEGIAN HAD THE WATER. The next step was to solve who lived where. The norwegian lived in the yellow house, the englishman lived in the red house, and because the japanese drank coffee, the japanese lived in the green house. This meant that the blue and the ivory houses were mutually inclusive to the ukranian and the spaniard. Since the blue house had a horse, and the spaniard had a dog, this meant that the ukrainian owned the blue house and the spaniard owned the ivory house. The next step was to solve who had what cigarettes previously incomplete. The old gold and the chesterfields belonged mutually inclusively to the ukrainian and the englishman. Since the ukrainian lived in the blue and had the horse, and the man with the snails also had the old golds, the ukrainian had the chesterfields and the englishman had the old golds. The next step was to solve who had what animals. The ukrainian had the horse, the englishman had the snails, and the spaniard had the dog. This meant that the fox and zebra belonged mutually inclusively to the norwegian and japanese. Since the japanese did not live next to the ukrainian, who had the chesterfields, he could not have the fox. Therefore, the norwegian had the fox and the JAPANESE OWNED THE ZEBRA.
