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: Which film won the Palme d'or the year that Dzieje grzechu was nominated? Passage:Borowczyk moved into live-action feature film with Goto, l'ile d'amour (Goto, Isle of Love) (1968) and Blanche (1971), both tales of illicit love thwarted by jealous husbands, and both starring his own wife, Ligia Branice. One of his most appreciated films of this period, Dzieje grzechu (A Story of Sin) (1975), which was nominated for Palme d'or, is an adaptation of a Polish literary classic by Stefan Zeromski. Like his 1966 short film Rosalie (a Guy de Maupassant adaptation and a Silver Bear winner), Dzieje grzechu had successfully rendered the themes of seduction and infanticide. Contes immoraux (Immoral Tales) (1973) and his later work, including Interno di un convento (Behind Convent Walls) (1977) (inspired by Promenades dans Rome of Stendhal) and Ceremonie d'amour (Rites of Love) (1988) have been controversial, lauded by some for their unique surrealist vision and derided by others as contentless pornography. Especially, La Bete (The Beast, 1975) (based on the novel Lokis by Prosper Merimee and originally conceived in 1972 as a film on its own, but then in 1973 as the fifth story in Contes immoraux) was seen by many as a decline in the director's career after Dzieje grzechu, except in France, where it was hailed by prominent critics such as Ado Kyrou. His 1980 film Lulu was based on the eponymous character created by Frank Wedekind.

Example Input: Question: What city did Empire Nightingale arrive in on July 1? Passage:Empire Nightingale would appear to have crossed the Atlantic Ocean from the United States independently, as she does not appear as a member of a convoy until 27 June, when she departed Middlesbrough, Yorkshire as a member of Convoy EC 31. The convoy had departed from Southend, Essex the previous day and arrived at the Clyde on 1 July. She left the convoy at Oban, Argyllshire, departing on 3 July for Baltimore, Maryland, United States, which was reached on 22 July. Empire Nightingale departed Baltimore on 10 August for Halifax, Nova Scotia, Canada, arriving five days later. Carrying a cargo of steel, she departed on 21 August with Convoy HX 146, which arrived at Liverpool, Lancashire on 6 September. She left the convoy at Loch Ewe to join Convoy WN 177, which departed from Oban on 5 September and arrived at Methil, Fife on 8 September. Empire Nightingale then joined Convoy FS 589, which departed that day and arrived at Southend on 10 September. She left the convoy at Hull, Yorkshire on 10 September.

Example Input: Question: Which team won more games the year Cowan started with the Rams, the Vikings or the Cowboys? Passage:Charles Edward Cowan (June 19, 1938 in Braeholm, West Virginia April 29, 1998 in Los Angeles, California) was an American football offensive tackle who played fifteen seasons in the National Football League with the Los Angeles Rams from 1961 to 1975. Cowan was a huge intimidating presence on the left of Tom Mack, a member of the Pro Football Hall of Fame, from 1966 to 1975, forming a potent left side of the offensive line, with help from Ken Iman at center from 1965 to 1975. In that 1961 to 1975 span, the Rams made the playoffs 5 times (1967,1969,1973,1974,1975), reaching the NFC championship game of the 1974-75 NFL playoffs and the 1975-76 NFL playoffs, but losing to the Minnesota Vikings and to the Dallas Cowboys, respectively. In the 1974 divisional round, the Rams defeated the Washington Redskins, as Cowan was successful against the opposing the right defensive end Verlon Biggs. In the 1975 divisional round, Doug France started in his place as the Rams defeated the St. Louis Cardinals. Cowan came back to play against the Cowboys, his final game, as the Rams could not get past them. Cowan was replaced by Doug France in 1976.
