Question: What was the population of the Principality of Samtskhe while Sargis II Jaqeli was the ruler? Passage:Sargis II Jaqeli () (1271 1334) was a Georgian prince (mtavari) and ruler of Principality of Samtskhe from 1306 to 1334. He was a son of Prince Beka I Jaqeli. During his father's reign Sargis participated in many campaigns. In 1290s Azat Mousa, leader of the Anatolian Turkoman tribes, attacked Samtskhe. Beka Jaqeli appointed Sargis as a commander of army and ordered him to stop Turks near village Vashlovani. Around 1303, Sargis defeated Turkoman tribes and expelled them from Meskhetian lands. In 1306, after his father's death, Sargis ascended the Atabeg's throne. He was made Amirspasalar by his nephew, King George V "the Brilliant". After Sargis II's death, his son Qvarqvare became a new Prince of Meskheti, also the vassal of Georgian kingdom.

Question: Who were the other members of the band that Patrick and Bill both left? Passage:Flags is a 1985 album by the duo Moraz-Bruford. Unlike their prior effort Music for Piano and Drums, which featured only an acoustic drum kit and grand piano, this recording expanded their musical palette by including a Kurzweil 250 synthesizer and electronic percussion. Keyboardist Patrick Moraz and drummer Bill Bruford had both previously been members of the progressive rock band Yes (though at different points in time) and also appeared together on Chris Squire's first solo album Fish Out of Water. During the recording of this album, Moraz was a member of The Moody Blues, while Bruford's band King Crimson had just begun a hiatus that would last for ten years. Flags features ten instrumental works, including a drum solo based on Max Roach's "The Drum Also Waltzes".

Question: How old was Ranald's father when he died? Passage:The Norse-Gaelic Clan Donald traces its descent from Domhnall Mac Raghnuill (d. circa 1250), whose father Reginald or Ranald was styled "King of the Isles" and "Lord of Argyll and Kintyre". Ranald's father, Somerled was styled "King of the Hebrides", and was killed campaigning against Malcolm IV of Scotland at the Battle of Renfrew in 1164. Clan Donald shares a descent from Somerled with Clan MacDougall, who traces their lineage from his elder son, Dugall mac Somhairle. Their dynasties are together commonly referred to as the Clann Somhairle. Furthermore, they are descended maternally from both the House of Godred Crovan and the Earls of Orkney, through Somerled's wife Ragnhildis Olafsdottir, daughter of Olaf I Godredsson, King of Mann and the Isles and Ingeborg Haakonsdottir daughter of Haakon Paulsson, Earl of Orkney. It remains uncertain if the Clann Somhairle are also descendants in some manner, through one or another of the above dynasts, of the House of Ivar, but this is commonly argued.
