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: What is the population of the city that headquartered Combined Forces Command - Afghanistan in 2004? Passage:Early in the Global War on Terror, Fontes served at US Central Command J5 overseeing issues of political-military cooperation in Afghanistan. In June 2004, she was moved to Combined Forces Command - Afghanistan headquarters in Kabul and served under David Barno as the head of the CJ5 staff for political-military coordination. Her staff was responsible for keeping General Barno "on message", overseeing the policies impacting military operations, and performing liaison work with both the Afghan Ministry of Defense and United Nations Assistance Mission in Afghanistan. At the end of her first year in Afghanistan and following Karl Eikenberry's assumption of command from Barno, Fontes volunteered to lead the Provincial Reconstruction Team (PRT) in Tarinkot. Daniel Green, the political adviser for the PRT, reported that though some Soldiers at the PRT had initial concerns due to her gender, those worries were shortly put to rest. She had been active in engaging with the Afghan people. Green said that Fontes, then a Lieutenant Colonel, pitched in a few hundred dollars of her own money to host a lunch on the PRT for local Afghan leaders. An article in Vanity Fair relates a story that she once refused to depart a meeting with Afghan elders in Chora District under threat of small arms fire, for fear of appearing weak in the face of the Taliban. Green asserts that in early 2006, she survived the first suicide vehicle-borne improvised explosive device attack in Urozgan Province due in part to the device's failure to detonate all of the mortar shells of which it was comprised. She departed Afghanistan in May 2006 to attend the US War College, graduating in 2007. She had been promoted that year to colonel. She was subsequently assigned as the chief of the American Security Assistance Office in Pakistan.

Example Input: Question: What was the previous episode that the 2005 one where the tenth doctor was introduced followed? Passage:The regeneration of the Ninth Doctor into the Tenth at the end of "The Parting of the Ways" (2005) used computer effects to morph Christopher Eccleston into David Tennant. In the episode of Doctor Who Confidential accompanying the episode "Utopia" (2007), where the same effect is used for the Master's regeneration, it is stated that the production team decided that this would be a common effect for all future Time Lord regenerations, rather than each regeneration being designed uniquely at the whim of the individual director. This style of transition is seen again in "The Stolen Earth"/"Journey's End" (2008) both when the Doctor undergoes an aborted regeneration, and when his hand spawns a clone in the second part; in The End of Time (2010) during which Matt Smith took over the role as the Eleventh Doctor; in "The Impossible Astronaut" when the Doctor is shot twice and seemingly killed; in "Day of the Moon" when a young girl regenerates; and in "Let's Kill Hitler" when Mels (Nina Toussaint-White) is shot and regenerates into River Song (Alex Kingston). "The Night of the Doctor" and "The Day of the Doctor" subsequently use the effect to show the Eighth Doctor and War Doctor's regenerations respectively. The Eighth Doctor's regeneration into the War Doctor uses steady beams of light as opposed to the flame effect used for other revived series regenerations. In the Series 10 episode "The Lie of the Land", the Twelfth Doctor fakes a regeneration as part of a plan to test if Bill still has free will. The effect used is consistent with the one used in the modern series, with the Doctor's hands glowing and emitting regeneration energy before he enters full regeneration. However, as the regeneration was not real, it did not use up a regeneration and the Doctor did not change bodies.

Example Input: Question: What was the population of Drogheda the year Connolly station was first opened? Passage:The station opened on 29 November 1844 by the Dublin and Drogheda Railway Company as Dublin Station, but was renamed Amiens Street Station ten years later after the street on which it is located. Originally the station served only a single mainline to Drogheda, and in 1853 through services to Belfast commenced. In 1891, the City of Dublin Junction Railway connected the station with Westland Row Station (now Pearse Station) on the city's South side. The City of Dublin Junction had a separate station known as Amiens Street Junction consisting of the present platforms 5, 6, and 7 (currently used by DART, Commuter and Rosslare services) with a separate street entrance. After the amalgamation of the GNR (I) at the end of the 1950s, this station became part of Amiens Street and the separate entrance fell into disuse. The City of Dublin Junction Railway allowed services to run from Amiens Street through to Westland Row to Rosslare and the South East. Services to Sligo were transferred to Westland Row (Pearse Station) running non-stop through the station in 1937, with the closure of Broadstone Station by CIE (see also MGWR). Services to Galway and Mayo also terminated at Westland Row, operating through Connolly Station after 1937, running via Mullingar and Athlone. This was discontinued in the 1970s in favour of running services from Heuston Station. Sunday trains to Cork, Limerick and Waterford during the 1960s operated from Connolly platforms 5, 6 and 7 through the Phoenix Park Tunnel, so as to avoid the cost of opening Heuston for the limited Sunday traffic demand at that time.
