In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. 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.

Example Input: Question: How many years after the Clairvaux was found, was the Margam Abbey founded? Passage:The abbey was founded in 1147 as a daughter house of Clairvaux by Robert, Earl of Gloucester, and was dedicated to the Blessed Virgin Mary. Early Christian crosses found in the close vicinity and conserved in the nearby Margam Stones Museum suggest the existence of an earlier Celtic monastic community. The founding abbot was William of Clairvaux. The third abbot, Conan, enjoyed the praise of Giraldus Cambrensis, whom he appears to have entertained prior to his official visit with Baldwin of Forde, Archbishop of Canterbury, to preach the Crusade in 1188. Conan (or Cunan) contributed to Patristic literature, as he is credited with the capitula or chapter-headings prefixing each section of St. Bernard's Sermons on the Song of Songs, one of the works for which that author was titled a Doctor of the Church.

Example Input: Question: Did Panos spend more years in schooling in Feltre or in Vicenza? Passage:Her artisan parents lost their jobs due to the industrialization in the region and so were forced to emigrate to the United States of America in 1902. Panas was left in the care of her paternal priest uncle Angelo who was a chaplain in Asiago and later the archpriest for Enego and who was living with his nurse sister Maria. Her schooling began under the Canossians in Feltre and later continued in Vicenza and on 5 August 1906 she made her First Communion. Panas remained in her uncle's care (receiving her initial education and religious formation from him) until her parents returned in 1910. Her parents returned with two new children Maximina and Rosa who had been born in the United States. In 1910 she moved to the Saint Alvise college in Venice and also attended the Nicolò Tommaseo Institute there before she graduated in 1913. It was following her graduation that she began teaching in the Conetta neighborhood of Cona close to Venice and it was there in 1914 that she met Father Luigi Fritz who would begin serving as her confidante and spiritual director until the end of their lives (which occurred within weeks of each other). It was also around this stage that Panas began keeping a journal and made the resolution that she would never write unless it was about or for Jesus Christ.
