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'île 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 Żeromski. 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 Cérémonie 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 Bête (The Beast, 1975) (based on the novel Lokis by Prosper Mérimée 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: Who was governor of the state in which Moore studied law in 1856? Passage:He was born in Lewisburg, Virginia in a portion of the state along the Ohio River which became West Virginia in his lifetime. His father had been born in Shenandoah County and moved across the Appalachian Mountains to the Greenbrier County area, but died when Charles was an infant. His paternal grandfather had married a daughter of Joseph Morgan, who helped settle the trans-Appalachian area. His mother, Augusta Delphia Page of Staunton, Virginia, a daughter of Major Charles Page, died in 1844 so Charles and his sister were raised by their uncle, George Moore in Mason County. When Charles was 16, he was sent to Marshall Academy in Huntington, and he would also study with John I Van Meter in Pike County, Pennsylvania, then attend Jefferson College (which later became Washington and Jefferson College) in Canonsburg, Pennsylvania. While at Jefferson College, Charles Moore helped found the Phi Kappa Psi fraternity before graduating in 1853. Moore then briefly attended Union College in New York. Returning to Virginia, he studied law at the University of Virginia and completed the course in 1856.

Example Input: Question: How many years did the ruler of the Sasanian Empire when it had confrontations with the Chionites rule the empire? Passage:Early confrontations between the Sasanian Empire of Shapur II with the nomadic hordes from Central Asia called the "Chionites" were described by Ammianus Marcellinus: he reports that in 356 CE, Shapur II was taking his winter quarters on his eastern borders, "repelling the hostilities of the bordering tribes" of the Chionites and the Euseni ("Euseni" is usually amended to "Cuseni", meaning the Kushans), finally making a treaty of alliance with the Chionites and the Gelani, "the most warlike and indefatigable of all tribes", in 358 CE. After concluding this alliance, the Chionites (probably of the Kidarites tribe) under their King Grumbates accompanied Shapur II in the war against the Romans, especially at the Siege of Amida in 359 CE. Victories of the Xionites during their campaigns in the Eastern Caspian lands were also witnesses and described by Ammianus Marcellinus.
