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: In what year did Ivan write Smrt Smail-age Čengića? Passage:Travelogue writer, brother of more noted Ivan, the writer of the well-known epic Smrt Smail-age Čengića. He attended a German school in his native town, where he was trained to become a blacksmith. Often he indulged into travels (Montenegro, Serbia), and exceptionally in a few occasions to Bosnia. In 1841 he was back to Novi, practicing his craft and agriculture, but also engaging in literature and cultural issues in general. In 1847 he ended up in Vienna, in 1848 again in Bosnia (in Sarajevo, at the court of Fazli-paša Šerifija). At the end of 1848, in a letter addressed to his brothers he says: "I don't know when I shall return home, for I have been, I'm afraid, created for this country. Turks are very fond of me for my prudence, they say, and rayah grows ever more trust in me, and therefrom there is no other outcome but mitre on the head or a stake in the arse". After Sarajevo, Matija went to Istanbul (though the exact dates cannot be ascertained), and according to some legends even further, to Suez and the Egypt. In 1852 Matija was back to Novi, where he settled until growing ill in 1879. He lived a secluded life until the symptoms of mind degeneration have started to show, finally dying in the sanatorium of a well-known psychiatrist Richard von Krafft-Ebing, near Graz, on April 17, 1881.

Example Input: Question: How many years of professional experience did Andy Seminick have when Mack Burk pitch-ran for the catcher? Passage:Burk stood tall, weighed and threw and batted right-handed. He attended the University of Texas at Austin and signed a $40,000 bonus contract with the Phillies in September 1955. Under the rules of the day, a "bonus baby" such as Burk was compelled to spend his first two years as a professional baseball player on a Major League roster. In his pro debut, on May 25, 1956, Burk pinch-ran for catcher Andy Seminick. In his third game, on June 5, he pinch hit for pitcher Curt Simmons in the fifth inning and singled off left-hander Joe Nuxhall of the Cincinnati Redlegs. He came around to score his first big-league run that inning on a sacrifice fly by Stan Lopata. He scored two more runs during the 1956 season, both as a pinch runner. In his lone appearance in the field, Burk caught one inning, the bottom of the eighth, in relief of Lopata on July 25 against the Cardinals, and handled one chance flawlessly.

Example Input: Question: In what year was the main group that was the subject of Naipaul's book formed? Passage:Black & White is a non-fiction book written by Shiva Naipaul and published by Hamish Hamilton in the U.K. in 1980. It was published with the title Journey to Nowhere: A New World Tragedy in the U.S. The book is based on Naipaul's trip to Guyana in the aftermath of the Jonestown Massacre, and his subsequent trip to the United States, in which he explored links between the People's Temple and other groups and individuals. Naipaul attempted to connect Rev. Jim Jones, founder of the People's Temple, with disparate parts of California's counterculture, and Guyanese and other Third World governments and the revolutionary ideologies which supported them. Naipaul was highly critical of these and other movements, including black theology, the nascent New Age movement and EST, in as much as they helped, in his analysis, to create fertile ground for the People's Temple to flourish on the two continents. The book's US paperback cover tagline reads "How American ideas and ideologies led to the mass suicide of 900 people in Jonestown, Guyana."
