Answer to Question 1
The focus is on a single man and woman as they dance to a sequence of different dance tunes/genres.
The male dancer exercises considerable control, determining both the dance tunes and their length; the woman may express herself by the way she dances.
After the beginning of the dance suite when a second male dancer turns the female onto the dance area, a group of women usually reintroduce the female dancer to the dance area for each subsequent dance. During the last dance when the male dancer turns the female dancer the suite ends.
Answer to Question 2
Europe may be defined physically as geographical landmass, culturally and as a concept that includes several island nations (e.g., the United Kingdom), the nation-states on the western end of the European continent to western Russia in the east, and to countries such as Sweden in the north and Greece in the south.
For much of its history Europe was divided into fiefdoms that were often governed by loosely defined kingdoms and later empires.
In recent times Europe may be perceived as a collection of independent democratic nation-states.
