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.

Input: Consider Input: Question: How many soldiers were killed in the battle that Philippe de Mézières 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 (1367–1368; 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.

Input: Consider Input: Question: How old was Derow's teacher and lasting influence at Oxford when Derow graduated from Oxford? Passage:Born in Newport, Rhode Island, Derow obtained his secondary education at The Roxbury Latin School in West Roxbury, Massachusetts. After an A.B. degree at Amherst (with Peter K. Marshall), he read for Greats as a second B.A. degree at Oxford in 1965–1967, achieving a First. At Oxford he was taught by, among others, W. G. (George) Forrest, who was a lasting influence. He completed a Ph.D. at Princeton on 'Rome and the Greek world from the earliest contacts to the end of the first Illyrian war', for which Professor J. V. A. Fine was his Advisor; in the preface to that work, he acknowledges the additional inspiration he had drawn from T. J. Luce and the historian and epigrapher C. Bradford Welles. After a spell of teaching at the University of Toronto, he returned to succeed Forrest at Wadham in 1977 when the latter was elected to the Wykeham Professorship of Ancient History at New College. In 2002–2005 Derow was also Director of Graduate Studies in ancient history for the Oxford Faculty of Classics.

Input: Consider Input: Question: Which of Hyam's male co-stars in Alias Jimmy Valentine was the oldest? Passage:She made her first film in 1924, and with her blonde hair, green eyes, delicate features, and good-natured demeanor, was cast in a string of supporting roles, where she was required to do very little but smile and look pretty. She proved herself capable of handling the small roles she was assigned, and over a period of time, she came to be taken seriously as an actress. By 1928, she was playing starring roles, achieving success in MGM's first talkie release, Alias Jimmy Valentine (1928) opposite William Haines, Lionel Barrymore, and Karl Dane. The following year, she appeared in the popular murder mystery The Thirteenth Chair, a role that offered her the chance to display her dramatic abilities as a murder suspect. At Fox that same year, she appeared in director Allan Dwan's now lost romantic adventure The Far Call opposite Charles Morton. The quality of her parts continued to improve as the decade turned, including a role as Robert Montgomery's sister in the prison drama The Big House (1930) with Chester Morris and Wallace Beery, for which Hyams once again received positive reviews. She then appeared in Surrender (1931) in which Warner Baxter and Ralph Bellamy desperately competed for her attention.
