In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as 'a' for Yes or 'b' for No.

Example Input: Question: What city that was chosen for filming Aeon Flux has the largest population? Passage:The screenplay was written by Phil Hay and Matt Manfredi, and directed by Karyn Kusama. It was based on the animated TV series by Peter Chung, who had a minor role in this film version of his work. In the early stages of production, actress Michelle Rodriguez was considered for the part of on. She had previously worked with Kusama in Girlfight. Kusama had originally suggested filming in Brasilia, the capital of Brazil, because the 20th-century modern architecture of that city fit with her vision of Bregna. The producers rejected the idea because Brasilia lacked the infrastructure and technical expertise to support a major film production. After several cities were scouted, Berlin and Potsdam in Germany were chosen for filming. Berlin had several locations that fit into the organic yet structured world of on Flux. The crew gained permission to film in several locations that had never allowed such access before, including the Treptow Crematorium, the Adlershof Trudelturm and Windkanal wind tunnel facility, and the Haus der Kulturen der Welt ("House of the World's Cultures"). Additional locations included the Bauhaus Archive and a dissection theatre built in 1790 to train veterinarians, part of the Berlin animal shelter. It was used as the Handler space. Filming was temporarily suspended for a month during September 2004 while Theron recovered from a neck injury she sustained during stunt-work on the tenth day of shooting. She was hospitalized in Berlin for five days and required about six weeks of physiotherapy to recover.

Example Input: Question: Was the man who consecrated Richardson in 1879 older than 50 at the time? Passage:Alfred Spencer Richardson was consecrated on 22 June 1879 in the Reformed Episcopal Church in Philadelphia, USA by William Rufus Nicholson, a bishop of the Reformed Episcopal Church, USA. WR Nicholson was consecrated for the Protestant Episcopal Church, USA on 24 February 1876 by Charles Edward Cheney who was consecrated (14 December 1873) by George David Cummins, American Episcopal assistant bishop of Kentucky, USA, and who was consecrated (15 November 1866) by John Henry Hopkins, Episcopal bishop of Vermont, USA. The line of succession to Hopkins is traceable from William Sancroft (enthroned archbishop of Canterbury, 1678) via Thomas White (bishop of Peterborough, England), George Hickes (assistant bishop of Thetford, England), James Gadderar (bishop of Aberdeen, Scotland), Thomas Rattray (bishop of Dunkeld, Scotland), William Falconer (or Falconar) (bishop of Caithness, Scotland), Robert Kilgour (bishop of Aberdeen, Scotland), Samuel Seabury (bishop of Connecticut, USA), Thomas Clagett (bishop of Maryland, USA), Edward Bass (bishop of Massachusetts, USA), Abraham Jarvis (bishop of Connecticut, USA), Alexander Viets Griswold (bishop of Eastern Diocese, USA) who in 1832 consecrated Hoskins.

Example Input: Question: How long had the process in which hydrogen peroxide processed been in development before it was patented? Passage:Today, hydrogen peroxide is manufactured almost exclusively by the anthraquinone process, which was formalized in 1936 and patented in 1939. It begins with the reduction of an anthraquinone (such as 2-ethylanthraquinone or the 2-amyl derivative) to the corresponding anthrahydroquinone, typically by hydrogenation on a palladium catalyst. In the presence of oxygen, the anthrahydroquinone then undergoes autoxidation: the labile hydrogen atoms of the hydroxy groups transfer to the oxygen molecule, to give hydrogen peroxide and regenerating the anthraquinone. Most commercial processes achieve oxidation by bubbling compressed air through a solution of the anthrahydroquinone, with the hydrogen peroxide then extracted from the solution and the anthraquinone recycled back for successive cycles of hydrogenation and oxidation.
