Question: Aside from the official forms of their respective languages, the four linguistic regions of Switzerland also have their local dialectal forms. The role played by dialects in each linguistic region varies dramatically: in the German-speaking regions, Swiss German dialects have become ever more prevalent since the second half of the 20th century, especially in the media, such as radio and television, and are used as an everyday language, while the Swiss variety of Standard German is almost always used instead of dialect for written communication (c.f. diglossic usage of a language). Conversely, in the French-speaking regions the local dialects have almost disappeared (only 6.3% of the population of Valais, 3.9% of Fribourg, and 3.1% of Jura still spoke dialects at the end of the 20th century), while in the Italian-speaking regions dialects are mostly limited to family settings and casual conversation.

Answer: How many linguistic regions of Switzerland have their own form of local dialect?


Question: Efforts by local kings to fight the invaders led to the formation of new political entities. In Anglo-Saxon England, King Alfred the Great (r. 871–899) came to an agreement with the Viking invaders in the late 9th century, resulting in Danish settlements in Northumbria, Mercia, and parts of East Anglia. By the middle of the 10th century, Alfred's successors had conquered Northumbria, and restored English control over most of the southern part of Great Britain. In northern Britain, Kenneth MacAlpin (d. c. 860) united the Picts and the Scots into the Kingdom of Alba. In the early 10th century, the Ottonian dynasty had established itself in Germany, and was engaged in driving back the Magyars. Its efforts culminated in the coronation in 962 of Otto I (r. 936–973) as Holy Roman Emperor. In 972, he secured recognition of his title by the Byzantine Empire, which he sealed with the marriage of his son Otto II (r. 967–983) to Theophanu (d. 991), daughter of an earlier Byzantine Emperor Romanos II (r. 959–963). By the late 10th century Italy had been drawn into the Ottonian sphere after a period of instability; Otto III (r. 996–1002) spent much of his later reign in the kingdom. The western Frankish kingdom was more fragmented, and although kings remained nominally in charge, much of the political power devolved to the local lords.

Answer: When did Alfred the Great begin his reign?


Question: The blue and red colours of the shirt were first worn in a match against Hispania in 1900. Several competing theories have been put forth for the blue and red design of the Barcelona shirt. The son of the first president, Arthur Witty, claimed it was the idea of his father as the colours were the same as the Merchant Taylor's School team. Another explanation, according to author Toni Strubell, is that the colours are from Robespierre's First Republic. In Catalonia the common perception is that the colours were chosen by Joan Gamper and are those of his home team, FC Basel. The club's most frequently used change colours have been yellow and orange. An away kit featuring the red and yellow stripes of the flag of Catalonia has also been used.

Answer:
When were the blue and red colors worn for a game by Barcelona?
