Input: Consider Input: Question: How old was Evrenos Beg when he first fought Pedro's forces at Leontari? Passage:On 6 September that year, Pope Urban VI declared that as James of Baux's successors had forfeited their rights to the Holy See, the principality belonged to him and he devolved its government on Paul Foscari, the archbishop of Patras, who in turn made Pedro vicar general. Pedro was constantly at war with the Despotate of Morea, against whom he even used Ottoman pirates, and the Duchy of Athens under Nerio I Acciaioli. The latter was captured near Vostitsa on 10 September 1389 while trying to sit to talks with Pedro concerning Argos and Nauplia. He had to buy his freedom with concessions to the Navarrese ally, Venice. Late in 1394 or early in 1395, the Turkish general Evrenos Beg invaded the despotate and met Pedro's forces at Leontari. Together the two besieged and took Akova (28 February). After Evrenos returned to Thessaly, Pedro was defeated by the Greeks and taken captive with the grand constable Andronico Asano Zaccaria, his brother-in-law. In December, Venice paid 50,000 hyperpers for the release of her allies.

Input: Consider Input: Question: What was the most famous song by the person who also had covered Dixon's song? Passage:A mixture of songs that inspired his own musical development, together with some of his own compositions, allied to a backing band and orchestra (The Caledonia Soul Orchestra) and several performances (as noted in the album's liner notes) that were recorded in concerts at The Troubadour in Los Angeles, California (24–27 May 1973), the Santa Monica Civic Auditorium (29 June 1973) and The Rainbow (23–24 July 1973) in London. These performance result in what Myles Palmer of the Times reviewed as demolishing "all barriers between the soul, blues, jazz and rock genres". The songs chosen went back to his days with Them with versions of "Gloria" and "Here Comes the Night". His first solo hit "Brown Eyed Girl" was performed but not included on the album until the reissue in 2008. M. Mark called the album "an intelligent selection of songs that draws on six of Morrison's records and five of the musicians he learned from." These musicians were Bobby Bland ("Ain't Nothing You Can Do"), Ray Charles ("I Believe to My Soul"), Sam Cooke ("Bring It On Home to Me"), two songs by Sonny Boy Williamson II ("Help Me" and "Take Your Hands Out of My Pocket") and a cover of a Willie Dixon song, "I Just Want to Make Love to You", which was popularized by Muddy Waters.

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.
