Document 2: Dutch language: Old Dutch naturally evolved into Middle Dutch. The year 1150 is often cited as the time of the discontinuity, but it actually marks a time of profuse Dutch writing and during this period a rich Medieval Dutch literature developed. There was at that time no overarching standard language; Middle Dutch is rather a collective name for a number of closely related dialects whose ancestor was Old Dutch. But they were all mutually intelligible. In fact, since Dutch is a rather conservative language, the various literary works of that time today are often very readable for modern-day speakers.

Document 5: Örebro SK: The 2003 season under new coach Stefan Lundin started well for Örebro, but yet again a poor ending of the season saw the team end up in eighth place. Promising goalkeeper John Alvbåge and Danish veteran Lars Larsen introduced themselves and soon became favourites of the Örebro crowd. The 2004 season became one of the darkest years in club history. First, Örebro had to fight hard to avoid relegation. A heroic effort with five straight wins at the end of the season earned a mid table finishing (seventh, later amended to eighth), but in the end effort proved futile. Economic problems had haunted ÖSK for a period of time as the club faced major deficits. Even after yet another heroic attempt by both supporters and sponsors the club was relegated by "Elitlicensnämnden" (eng: The Elite license board), who ruled that the balance sheet of the club did not comply with the standards of the Swedish Football Association. Örebro SK's appeal failed and the club was forced to play in Superettan.

Document 8: Old English: Old English developed from a set of Anglo-Frisian or North Sea Germanic dialects originally spoken by Germanic tribes traditionally known as the Angles, Saxons, and Jutes. As the Anglo-Saxons became dominant in England, their language replaced the languages of Roman Britain: Common Brittonic, a Celtic language, and Latin, brought to Britain by Roman invasion. Old English had four main dialects, associated with particular Anglo-Saxon kingdoms: Mercian, Northumbrian, Kentish and West Saxon. It was West Saxon that formed the basis for the literary standard of the later Old English period, although the dominant forms of Middle and Modern English would develop mainly from Mercian. The speech of eastern and northern parts of England was subject to strong Old Norse influence due to Scandinavian rule and settlement beginning in the 9th century.
