In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage. Your job is to determine whether information from more than one term is needed to answer the question. Indicate your choice as 'a' for Yes or 'b' for No.

Example Input: Question: How many months before the buildup to Knightfall did the death of Superman occur? Passage:Within the regular series, the buildup to "Knightfall" begins with a six-issue run in Batman #484-489 (September 1992 - February 1993), in which Batman (at the onset of a personal psychological mid-life crisis) is forced to deal, in rapid succession, with the returning villain Black Mask and his gang (who target Bruce Wayne and Lucius Fox), a crazed killer called Metalhead, and a sharpshooter assassin hired by an imprisoned mobster to murder Commissioner Gordon. Batman begins to feel that he has lost his edge, especially after his failure to capture Black Mask. He finds himself unable to meditate or even focus. As Bruce Wayne, he contacts holistic therapist Shondra Kinsolving for treatment. He also assigns Robin (Tim Drake) to train Jean-Paul Valley in detective work to aid them as an ally, hoping to guide Valley's brainwashing away from making him a villainous threat. Despite the advice of everyone in his life, including Dr. Kinsolving, Bruce refuses to rest and continues to pursue his self-imposed duty despite his worsening condition (although not explicitly noted as a cause, these events take place immediately after the death of Superman, Batman's peer, elsewhere in the DC Universe).

Example Input: Question: Who was the ruler of Prague the year young Alfred was sent there? Passage:Piccaver was born on 5 February 1884 in the Lincolnshire town of Long Sutton to chemist Frederick Herman Piccaver (born 1864, died 17 February 1916) and his wife Sarah Ann Sissons. The Piccavers had been farm laborers, but there were also claims of Spanish ancestry dating back to the Spanish Armada. At a young age, Alfred emigrated with his family to the United States of America. The family resettled in Albany, NY and took American citizenship. Frederick Piccaver worked as head brewer of the Beverwyck Brewery. Alfred joined the choir of Albany's St. Peter's Episcopal Church as a boy soprano. He also became a soloist at the North Reformed Church in Watervliet. The young Piccaver went on to study voice with S. Graham Nobbes, who had been chief instructor of the Emma Willard Conservatory of Music and with Allan Lindsay, conductor of the Troy Conservatory of Music. Alfred later trained to be electrical engineer but he had a talent for singing and in 1905 he enrolled at the Metropolitan School of Opera. The school's director Heinrich Conried recognised his considerable vocal ability and in 1907 sent the young Alfred to Prague, where he studied with Ludmilla Prochazka-Neumann (18721954).

Example Input: Question: In what country does the Socialist, Radical, Citizen and Miscellaneous Left group operate? Passage:After leaving the PS along with Jean-Luc Melenchon to co-found the Left Party, Marc Dolez left the Socialist, Radical, Citizen and Miscellaneous Left group to join the GDR group as an associate deputy before becoming a member on 27 January 2009. On 11 July 2010, Anny Poursinoff of the Greens was elected in a by-election in Yvelines's 10th constituency, defeating Jean-Frederic Poisson, thus becoming the 26th member of the GDR group. On 1 September 2010, the Green deputy Yves Cochet took over the presidency of the GDR group. Maxime Gremetz was expelled from the group on 12 April 2011 after interrupting a parliamentary meeting about the Fukushima Daiichi nuclear disaster, and subsequently resigned from his seat on 16 May. Cochet left the GDR group on 6 December after being designated as an MEP, and was replaced by Roland Muzeau; this decision reflected the dissatisfaction of the Left Front at the decision of their ecologist partners, now known as Europe Ecology The Greens (EELV), to present a common candidate with the PS against incumbent Francois Asensi in Seine-Saint-Denis's 11th constituency. The four ecologist deputies subsequently left the GDR group, Cochet departing on 6 December to take his seat as an MEP and the three others quitting on 7 December. Jacques Desallangre left the group on 17 February 2012.
