Input: Consider Input: Question: What year was Brian named the High King? Passage:The Uí Briúin Seóla was one of the major branches of the powerful Uí Briúin dynasty, which had become the dominant force in Connacht by the 8th century. The genealogies list two sons of Murchadh mac Maenach: Urchadh and Urumhain. Urchadh mac Murchadh, King of Maigh Seóla (also listed as king of Iarthair Connacht, died 945, in the 14th century Book of Ballymote) was father of Bé Binn inion Urchadh, Princess of the Uí Briúin Seóla and Queen of Thomond (fl. early 10th century). Bé Binn married Cennétig mac Lorcáin of Thomond to produce a son who would become the High King of Ireland (Irish: Ard-Rí na hÉireann): Brian Bóruma mac Cennétig, known in English as Brian Boru (c. 941–23 April 1014). Brian broke the near monopoly of the Uí Néill over the High Kingship of Ireland and fought to unite Ireland as a people under one, native king. His father, Cennétig mac Lorcáin of Thomond, was one of the principal leaders of the resistance to the Danish Viking incursions. Cennétig had several wives and children but positively assigned Bé Binn as the mother of Brian Bóruma.

Input: Consider Input: Question: What is the elevation of the land formation near where Khaplang was born? Passage:Khaplang was born in Waktham in April 1940, a village east of Myanmar's Pangsau Pass as the youngest of ten children. Born into Hemi Naga tribe that lived predominantly in Myanmar, his early childhood was shaped by the opening up of isolated Naga communities by the World War II. During the War, the Western Allies built the long Stilwell Road connecting Ledo in India's Assam to China's Kunming to carry supplies against the Japanese Army, that passed through Waktham. This was said to have "sowed the seeds of insurgency in Khaplang." Khaplang claimed that he first attended a school in Margherita, a town in Assam before joining Baptist Mission School in Myitkyina in Myanmar's Kachin State in 1959, and in 1961 to another missionary school in Kalay before he eventually dropped out.
