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: Which country was Bracton born in? Passage:Plucknett describes Bracton in this way: "Two generations after Ranulf de Glanvill we come to the flower and crown of English jurisprudence – Bracton." Bracton was born around 1210 in Devon and had a great deal of preferment in the Church. He either derived from Bratton Fleming or Bratton Clovelly. Both villages are in Devon. It was only after his death that the family name appears as Bracton; during his life, he was known as Bratton, or Bretton. This originally may have been Bradton, meaning "Broad Town". Bracton first appeared as a justice in 1245. From 1248 until his death in 1268 he was steadily employed as a justice of the assize in the southwestern counties, especially Somerset, Devon and Cornwall. He was a member of the coram rege, also called the coram ipso rege, later to become the King's Court. He retired from this in 1257, shortly before the meeting of the Mad Parliament in 1258 at Oxford. It is unknown whether his retirement was related to politics. His leaving coincided with the onset of the notorious Second Barons' War in 1264. At that time Bracton was ordered to restore to the Treasury the large store of plea rolls (case records from previous trials) that had been in his possession. He was also forced to surrender the large number of rolls from his predecessors Martin Pateshull and William Raleigh, also known as William de Raley. It cannot be determined whether he disgraced the King or the barons in this affair, but it is speculated that some kind of political intrigue was involved. The practical result was that his major work, De Legibus et Consuetudinibus Angliae ("The Laws and Customs of England"), was left unfinished. Even so, it exists in four large volumes today. He continued to follow the assizes in the southwest until 1267. In the last year of his life he filled another prominent role, as member of a commission of prelates, magnates and justices appointed to hear the complaints of the "disinherited" – those who had sided with Simon de Montfort, 6th Earl of Leicester.

Example Input: Question: What was the capital of the Republic of Rawanda? Passage:In 1962, the Belgian mandate of Ruanda-Urundi received independence, creating the Republic of Rwanda and the Kingdom of Burundi. Both states had traditionally had monarchies dominated by the Tutsi ethnic group over a Hutu ethnic majority but Rwanda's monarchy was abolished by a political revolution in 1959-61. In the first years of independence, Burundi seemed to have achieved a balance between ethnic groups which brought members of the different ethnic groups into government, moderated in part by the mwami (king) Mwambutsa IV who was popular with all groups but was himself Tutsi. Both Tutsi, Hutu and Ganwa were part of the dominant political party, the Union for National Progress (Union pour le Progrès national, UPRONA). In October 1961, shortly before the date scheduled for independence, the Burundian Prime Minister Prince Louis Rwagasore was assassinated, raising ethnic tensions in the country. After a period of rule by Tutsi prime ministers, Mwambutsa appointed Burundi's first Hutu leader, Pierre Ngendandumwe, but Ngendandumwe was assassinated in January 1965 by a Rwandan Tutsi. Elections held in May 1965 took place in an atmosphere of strong ethnic tension. Hutu candidates gained a majority, but Mwambutsa deposed the Hutu Prime Minister Joseph Bamina and instead installed a Tutsi candidate, Léopold Biha, in October 1965.

Example Input: Question: Were the scenes for the Elysium station shot entirely in North America? Passage:Elysium was produced by Bill Block, Neill Blomkamp, and Simon Kinberg, and written and directed by Neill Blomkamp, the director and co-writer of District 9 (2009). It reunites Blomkamp with some of his District 9 crew, such as editor Julian Clarke, production designer Philip Ivey, cinematographer Trent Opaloch, and actor Sharlto Copley, playing one of the film's antagonists. Elysium is a co-production of TriStar Pictures and MRC. Although the film's story is set in 2154, Blomkamp has stated that it is a comment on the contemporary human condition. "Everybody wants to ask me lately about my predictions for the future," the director has said, "No, no, no. This isn't science fiction. This is today. This is now." In January 2011, independent studio Media Rights Capital met with major studios to distribute Elysium, and Blomkamp shared art designs of his proposed science fiction film. The art designs won over the executives at Sony Pictures, who bought the film after making a more attractive offer than the other studios. With a production budget of , production began in July 2011. The film's Earth-bound scenes were shot in a dump in the poor Iztapalapa district on the outskirts of Mexico City, while the scenes for Elysium were shot in Vancouver and the wealthy Huixquilucan-Interlomas suburbs of Mexico City. Matt Damon shaved his head for the role of Max. The main role was first offered to Watkin Tudor Jones (aka Ninja), a South African rapper, who despite being a fan of District 9 (he has a D9 tattoo on his inner lip) did not take the role. The role was then offered to rapper Eminem, but he wanted the film to be shot in Detroit. That was not an option for the two studios, so Blomkamp moved on to Damon as his next choice. Futuristic designs were executed by Philip Ivey after long periods of researching and studying older science fiction films. Ivey has continuously cited Syd Mead as a substantial influence for the film. Weta Workshop created the exosuits for Damon and Copley's characters, while the complicated visual effects were handled primarily by Image Engine (who also collaborated on District 9) with additional work by Whiskytree, MPC, The Embassy and Industrial Light and Magic. Re-shoots took place through October 2012. The film's music score was composed by newcomer Ryan Amon and recorded at Abbey Road Studios with the Philharmonia Orchestra. The soundtrack was released on August 6, 2013.
