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 official position of the Ministry of Foreign Affairs of the People's Republic of China is that the Ming implemented a policy of managing Tibet according to conventions and customs, granting titles and setting up administrative organs over Tibet. The State Council Information Office of the People's Republic states that the Ming dynasty's Ü-Tsang Commanding Office governed most areas of Tibet. It also states that while the Ming abolished the policy council set up by the Mongol Yuan to manage local affairs in Tibet and the Mongol system of Imperial Tutors to govern religious affairs, the Ming adopted a policy of bestowing titles upon religious leaders who had submitted to the Ming dynasty. For example, an edict of the Hongwu Emperor in 1373 appointed the Tibetan leader Choskunskyabs as the General of the Ngari Military and Civil Wanhu Office, stating:

Answer: Who abolished the policy council?


Question: While most artists became established in other formats before moving to adult contemporary, Michael Bublé and Josh Groban started out as AC artists. Throughout this decade, artists such as Nick Lachey, James Blunt, John Mayer, Bruno Mars, Jason Mraz, Kelly Clarkson, Adele, Clay Aiken and Susan Boyle have become successful thanks to a ballad heavy sound. Much as some hot AC and modern rock artists have crossed over into each other, so too has soft AC crossed with country music in this decade. Country musicians such as Faith Hill, Shania Twain, LeAnn Rimes and Carrie Underwood have had success on both charts.

Answer:
Along with Josh Groban, what notable pop artist started out his career on adult contemporary radio?
