而仔细看题目：绿色房子在白色房子左面。
严谨看待这个条件的话的话，可以分析出另一种可能性，就是绿色房子和白色房子不是隔壁，这时就有：
————————————————————
                   1                     2                     3                     4                     5
颜色               绿色                  蓝色                   白色                  红色                  黄色
国籍               挪威                                      不是丹麦                 英国
饮料               咖啡                                         牛奶                 不是茶
宠物                                                                                  马
香烟                                                                                                     Dunhill
对（1）进行分析，根据信息：“抽Blends香烟的人有一个喝水的邻居，抽Blends香烟的人住在养猫的人隔壁”推断出：
（1.1）
                   1                     2                     3                     4                     5
颜色              绿色                   蓝色                   白色                  红色                  黄色
国籍              挪威                                        不是丹麦                英国
饮料               咖啡                   茶                    牛奶                  啤酒                   水
宠物                                                            猫                     马
香烟                                                                                Blends                Dunhill
而抽Blue Master的人喝啤酒和推论矛盾，所以抽Blends的不可能是4
当因为“抽Blends香烟的人有一个喝水的邻居”，于是还有可能是2的饮料为水，那么有两种情况。
（1.2）
                   1                     2                     3                     4                     5
颜色              绿色                   蓝色                   白色                  红色                  黄色
国籍              挪威                                        不是丹麦                英国
饮料              咖啡                    水                    牛奶                  不是茶
宠物                                                                                  马
香烟             Blends                                                                                   Dunhill
4不是茶，那么5一定是茶，并住的是丹麦人推导出：
（1.2）
                   1                     2                     3                     4                     5
颜色              绿色                   蓝色                   白色                  红色                  黄色
国籍              挪威                                        不是丹麦                英国                  丹麦
饮料              咖啡                    水                    牛奶                  啤酒                   茶
宠物                                     猫                                            马
香烟             Blends                                                          Blue Master              Dunhill
而瑞典人养狗，所以3是瑞典人，2是德国人，并且抽Prince，而瑞典人抽的是Pall Mall推导出：
（1.2）
                   1                     2                     3                     4                     5
颜色              绿色                   蓝色                   白色                  红色                   黄色
国籍              挪威                   德国                   瑞典                  英国                   丹麦
饮料              咖啡                    水                    牛奶                  啤酒                   茶
宠物               猫                     狗                     马
香烟             Blends                 Prince                Pall Mall           Blue Master             Dunhill
而根据“抽Pall Mall 香烟的人养鸟”可知道与题矛盾，所以所以抽Blends的不可能是1，这样的情况不成立。
