debundesliga1-1, Exercise 2: Promotion and relegation

Model answer:

In a pyramid, the lowest-placed clubs in a division drop to the one below at the end of the season (relegation), and the best clubs from the division below move up (promotion), sometimes with a play-off for one place.

It matters because every match has consequences at both ends of the table, a small club can reach the top division, and a big club can fall. This differs from closed leagues without relegation. Details of the current format should be checked.
