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 soldiers were killed in the battle that Philippe de Mezieres was knighted after? Passage:Philippe belonged to the poorer nobility. At first, he served under Luchino Visconti in Lombardy but within a year he entered the service of the husband of Joanna I of Naples, Andrew, Duke of Calabria, who was the son of the King Charles I of Hungary. Andrew was assassinated very soon in September 1345. In the autumn of that year, Philippe set out for the East in the French army. After the Battle of Smyrna in 1346 he was made a knight, and when the French army was disbanded, he made his way to Jerusalem. He realized the advantage which the discipline of the Saracens gave them over the disorderly armies of the West, and conceived the idea of a new order of knighthood, but his efforts proved fruitless. The first sketch of the order was drawn up by him in his Nova religio passionis (13671368; revised and enlarged in 1386 and 1396). From Jerusalem he found his way in 1347 to Cyprus to the court of Hugh IV, where he found a kindred enthusiast in the king's son, Peter of Lusignan, then count of Tripoli; but he soon left Cyprus, and had resumed his career as a soldier of fortune when the accession of Peter to the throne of Cyprus (Nov. 1358) and his recognition as king of Jerusalem induced Philippe to return to the island, probably in 1360, when he became chancellor.

Example Input: Question: Did Charles Jones win any tests in the Caribbean? Passage:In 1930, when the MCC visited the Caribbean under the leadership of F.S.G. Calthorpe, Jones played against them three times in February, twice for British Guiana and once whilst making his Test Match debut. His selection for the 3rd Test of the four-match series, played at Bourda, Georgetown was more to do with the West Indies' usual policy of using a few players from the host island in an effort to keep the expenses down. In an historic victory over England, Jones' contribution was minimal, scoring just 6 and 2, taking two catches but failing to take a wicket with the ball. He played only occasionally for the next five years but aided by some useful scores with the bat in that time, Jones made a further three Test appearances against England sides led by R.E.S. Wyatt in 1935. In the second Test of the series, played at Port-of-Spain, Trinidad, and where he opened with C.M. Christiani, he scored 19 runs in both innings. This subsequently proved to be his highest Test score but he failed to take a single Test wicket in his career. In all first-class matches he took 24 wickets at an average of 44.12 apiece and scored 917 runs at an average of 21.83. In a career that ended in January 1939, his highest score was an unbeaten 89, scored at home in a comprehensive victory over Barbados. No Obituary appeared within the pages of Wisden for Jones.

Example Input: Question: How long did Franco rule Spain as dictator? Passage:The 1977 Atocha massacre, a part of neo-fascist terrorism in Spain, was an attack during the Spanish transition to democracy after the death of Franco in 1975, killing five and injuring four. It was committed on January 24, 1977, in an office located on 55 Atocha Street near the Atocha railway station in Madrid, where specialists in labour law, members of the Workers' Commissions (Comisiones Obreras, CCOO) trade union, and of the then-clandestine Communist Party of Spain (PCE) had gathered. The next day, the massacre was defended by a group calling itself Alianza Apostolica Anticomunista (literally Apostolic Anticommunist Alliance, abbreviated Triple A or AAA). The suspects arrested were close to Blas Pinar's Fuerza Nueva far-right party, the Falange-JONS and the Franco Guard. The indignation brought about by the killings accelerated the legalisation of the Communist party, which took place in Easter 1977. On March 24, 1984, the Italian daily Il Messaggero stated that, possibly, Italian neo-fascists had taken part in the shootings, pointing toward some kind of "Black International". This allegation was confirmed by a report from the Italian CESIS, which confirmed that Carlo Cicuttini, who was also involved in the Peteano massacre, took part in the Atocha massacre.
