Question: Whom founded sixdegrees.com? Passage:This newer generation of social networking sites began to flourish with the emergence of SixDegrees.com in 1997, followed by Open Diary in 1998, Mixi in 1999, Makeoutclub in 2000, Hub Culture and Friendster in 2002 or Canada's first online social network Nexopia in 2003, and soon became part of the Internet mainstream. However, thanks to the nation's high Internet penetration rate, the first mass social networking site was the South Korean service, Cyworld, launched as a blog-based site in 1999 and social networking features added in 2001. It also became one of the first companies to profit from the sale of virtual goods. Friendster was followed by MySpace and LinkedIn a year later, and eventually Bebo. Friendster became very popular in the Pacific Islands. Orkut became the first popular social networking service in Brazil (although most of its very first users were from the United States) and quickly grew in popularity in India (Madhavan, 2007). Attesting to the rapid increase in social networking sites' popularity, by 2005, it was reported that Myspace was getting more page views than Google. Facebook, launched in 2004, became the largest social networking site in the world in early 2009. Facebook was first introduced as a Harvard social networking site, expanding to other universities and eventually, anyone. The term social media was introduced and soon became widespread.

Question: Which monarch involved in the Byzantine-Bulgarian wars was born first? Passage:With the ascendance of Simeon I to the throne in 893, the long-lasting peace with the Byzantine Empire established by his father was about to end. A conflict arose when Byzantine Emperor Leo VI the Wise, acting under pressure from his wife Zoe Zaoutzaina and her father, Stylianos Zaoutzes, moved the marketplace for Bulgarian goods from Constantinople to Thessaloniki, where Bulgarian merchants were heavily taxed. Forced to take action, in the autumn of 894 Simeon invaded the Byzantine Empire from the north, meeting little opposition due to the concentration of most Byzantine forces in eastern Anatolia to counter Arab invasions. Informed of the Bulgarian offensive, the surprised Leo sent an army consisting of guardsmen and other military units from the capital to halt Simeon, but his troops were routed somewhere in the theme of Macedonia.The Magyars managed to defeat Simeon's army twice, but in 896 they were routed in the Battle of Southern Buh. The war ended in 896 with a great Bulgarian victory near Bulgarophygon in Eastern Thrace. The market was returned to Constantinople, and the Byzantine Emperor had to pay annual tribute to Bulgaria. More importantly, with help from the Pechenegs Simeon successfully fended off a Magyar invasion, which was coordinated with the Byzantines.

Question: How old was the person who owned Wigginton just before the Corbets at the time of his death? Passage:In the 11th century, Wigginton was under the control of a half-brother of William I, Robert, Count of Mortain. However, in 1086 the Domesday Book indicated that Wigginton had not been gifted to him but was probably acquired by force by Robert from two adjacent estates close to Tring, one of which had previously been in the hands of Edith of Wessex. During the 13th century Wigginton formed part of the estate at Little Gaddesden passing first to the de Broc family and then, through marriage to the de Lucys. After the death of Sir William Lucy in 1466 it was in the ownership of the Corbets for over 130 years. The manor was then the subject of successive legal challenges fought out in the Court of Chancery until it came into the possession of Sir Richard Anderson of the manor of Pendley during the 1650s. Elizabeth Spencer (née Anderson) inherited Wigginton and became the third wife of Simon Harcourt, 1st Viscount Harcourt 1703. The manor remained in the Harcourt family until the 1860s. Colonel Charles Harcourt had died in 1831 leaving the manor to his three daughters, Sarah, Elizabeth and Alice who jointly sold it to Rev. James Williams in 1868. Wigginton Common was enclosed in 1854 and was subsequently incorporated into the Tring Park Estate owned at the time by the Rothschild Family.
