Example Input: Question: Was Willemstad successfully defended against the French in 1793? Passage:By the 1790s Braak was in the Caribbean, and was present at the defence against the French of Willemstad, part of the Dutch colony at Curacao, in 1793. By late 1794 she was ordered to escort a convoy of East Indiamen to Batavia in the Netherlands East Indies. En route she called at the English port of Falmouth, unaware that the French had since invaded the Netherlands and proclaimed the Batavian Republic as a client state, compelling the Dutch to declare war on the British. On the arrival of the convoy at falmouth, the Royal Navy seized the 26 merchantmen and six warships of the convoy, including De Braak. A boarding party from the sloop-of-war took over De Braak. Forty-six Royal Navy vessels that were at Plymouth shared in the prize money.

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 Output: b
