Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

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: Which teacher who taught Torquemada at the convent died first? Passage:There are few firm biographical details concerning Juan de Torquemada, most of which have to be deduced from his own work. Even basic information is subject to uncertainty and controversy. Born at Torquemada, Palencia, north central Spain, at an unknown date before 1566 (Miguel León-Portilla argues in detail for 1562) he was brought by his parents to New Spain probably while still a child. He took the Franciscan habit, as is generally agreed, in 1579, and pursued a course of studies in Latin, theology, philosophy and Nahuatl. Brief notices in his own works put him at the convent in Tlacopan in 1582 and (while still a youth) at the convent in Chiauhtla - the presumption being that these relate to his novitiate. It is uncertain if he began his studies at the convento mayor de San Francisco in Mexico City, but it is presumed that part at least of his studies were conducted while resident at the convent of Santiago, Tlatelolco. Among his teachers he names fray Juan Bautista (who taught him theology) and Antonio Valeriano (who taught him Nahuatl and whom he especially praised for his talents). At some time in the early 1580s he was sent by his superiors to Guatemala where he encountered the conquistador Bernal Díaz del Castillo. By 1584 he was certainly at the convent of San Francisco, where he assisted in the infirmary. The conjectured date of his priestly ordination is 1587 or 1588.
