C, by condition 1, 4, 5 and the blue house and milk know all the house location (because the green position is fixed to a left one right, must be together not separate, so only 4, 5 position is, red and the United Kingdom together so can only be 3 position) d, by the conditions 5 know the location of the coffee. E, by condition 1 know the location of the United kingdom. F, the location of the Dunhill is known by the condition 7. G, the location of the condition 11 and Dunhill know the location of the horse. H, by the conditions of 2, 3, 12, 15, and milk, coffee, Norway, Ma, Dunhill position to know the location of the water (because the tea and beer in order to correspond to the location of the 1 have the remaining three drinks on the remaining white water, so the location determined). I, the location of the is known as blend. J, the location of the 2 and the horse by the location of the horse knows the location of Denmark and tea. K, all drinks are not determined, so the beer is also determined by the location of the bluemaster 12. L, the state is only Germany and Sweden did not determine, because the 5 position has bluemaster, so Germany, Sweden's position is also determined by the conditions of 13 know the location of prince. M, the location of the dog by the condition 2. N, look at the table to know now pallmall position also know, by condition 6 know the position of birds. O, the location of the 10 and the birds know the location of the cat. In the last table, there is only one blank, which is the location of the fish.

First, browse through the whole topic, write down the link between the various elements of the subject, and then begin to analyze.

1, from"Located in the middle of the house to drink milk""Norway people live in the first house.""Norway people live in blue house next door"As shown in the figure: this time can determine the A, B, C information.

2,"The green house is on the left of the White House.""Green housing owners drink coffee"From the first sentence, the green can only be 3 or 4 of the house, but because the owner of the 3 house drink is milk, combined with second sentences can determine the D, E, F three, and because of the British people living in the red house, and the Norway people living in the middle of the house (serial number 3), the British people, and then know that Norway's house is yellow, and can be based on"Yellow homeowner smokes Dunhill""The next horse owners in pumping Dunhill family"The information in the two J, K, is determined;

3,"Blue master homeowners drink beer ", from the analysis of the 1, 2 points above, pumping blue master homeowners may live in second or fifth houses. First assume that the owner of the house in second, such as figure, from the "drink tea" tips that the Danish people living in room 5, and then from the "German prince" inferred that the German people living in the house fourth, so that the Swedish people live in the house, but according to the tips of the 1, 2, 2 steps, 2 house owners have a horse. It can be deduced that the owner of the master blue is a 5 house, but not 2;

Figure 4, L and M, to determine the two information, the "Danish tea" this information to determine the N, O two, and then drink boiling water can be determined by the people of Norway people (in the number 1, and then through the house) "only drink boiling water of the people who live next door to pull blend" determination of Q, "the German pumping Prince R, S, and T can be derived from" pall mall, the owner of the cigarette smoke that U aviculture "information," the Swedish dog "that V, W," by the man who smokes blend people live in the cat next door "that cat the master is Norway people, and finally come to the conclusion that the fish is the owner of the analysis is complete German.

Evolution_language

First step:First determine the order of the color of the house

The people of Norway in the first room, and the people of Norway next to the blue house, then the blue house must be second rooms, and because the green in the White House on the left, have known second house color is blue, so the combination is not a green and white, some rooms and second rooms. So, there may be third and fourth or fourth combination and fifth combination, and because the owners drink milk, and the owner of green coffee, combined exclusion of third rooms and fourth rooms, is green and white are fourth and fifth, and because the British people live in red in the house, Norway is the first room, the room's color is yellow, which is the first room, then the English people live in the third room.
Second step:Confirmation of the nationality of the color room

A step the first room (yellow) for Norway, third rooms (red) for the United Kingdom, has the yellow house the first room owners smoke is dunhill, then the horse is second rooms (blue) raised. So the Swedes can only be green or white, Danish is blue or white, Germany may be blue, green or white, then there will be two reasonable combination, the first one is Germany is blue, Sweden is green, Denmark is white, second combinations of Denmark is blue, Germany is green, Sweden is white. First look at the first. If Germany is blue, so he smokes is prince, because Dunhill is yellow, blue Sergio prince, respectively. The red and green is milk and coffee, then bluemaster is white, but the bluemaster of the owner and the beer, and white Color is Denmark, the Danish people drink tea in contradiction to each other, so it is only second, that is because the blue Denmark Danish red green tea, milk, coffee, bluemaster beer, already obtained the yellow is dunhill, then bluemaster is the owner of the white cigarette, and drink beer also, because the Germans smoke prince, ruled out white house, then the German green house, so the Swedish must is the White House.
Third step:Confirm the corresponding type of cigarette
From the second step is to know that the green is prince, white is dunhill, yellow is dunhill, pallmall is a bird, blue is the horse, then the red house is pallmall, the bird is a bird, corresponding to a blend, then the corresponding is blue.

Fourth step:Confirm all the drinks.

The first three steps can be aware of the Danish (blue) is the counterpart of the tea (blend), the United Kingdom corresponds to milk, Germany is the counterpart of coffee, Sweden is corresponding to beer, boiling water in the blend next door, then the water will be Norway (yellow)

Fifth step:Recognized animal
(blue) blend is a horse, pallmall (red) is a bird, the Swedish bluemaster blend pumping dogs, cats in the house next door, so only one do not determine the next, namely yellow cat dunhill, then only the Germans fish;
