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 much were KSEE's non-license assets purchased for by the  Nexstar Broadcasting Group? Passage:On February 6, 2013, Granite sold KSEE's non-license assets to the Nexstar Broadcasting Group, with Nexstar also intending to purchase KSEE's license following Federal Communications Commission approval; in the interim, Nexstar operated the station via a time brokerage agreement. The deal made KSEE a sister station to CBS affiliate KGPE, which Nexstar had just acquired from Newport Television. Normally, duopolies between two "Big Four" affiliates, let alone "Big Three," would not be allowed because those stations are usually the four highest-rated stations in a market, which FCC regulations do not allow any common ownership of. However, according to Nielsen, in 2013 KGPE was ranked as the fourth highest-rated station in the market and KSEE fifth, after KFSN (ABC), KFTV (Univision), and KMPH-TV (Fox), allowing a duopoly to be formed between the stations. This marked the second instance (after the Gannett Company purchased ABC affiliate WJXX in Jacksonville, Florida, creating a duopoly with that market's NBC affiliate WTLV, in 2000) in which a single company owns a duopoly involving two stations that are affiliated by a Big Three television network; and is also Nexstar's first true Big Three duopoly (Nexstar's other Big Three duopolies are virtually formed, in which the other station is owned by Mission Broadcasting). The merger was approved on April 17, and completed by May 31.

Example Input: Question: In what year was the party founded that defeated James Cameron in 1920? Passage:He was born in Logie-Almond in Perthshire to farmer Alexander Cameron and Anne Pullar. The family moved to Victoria in 1854, settling first at Batesford and then at Beremboke. Cameron became a farmer at Orbost, and also developed business interests in mines at Nowa Nowa and in farm machinery. On 30 April 1879 he married Sarah Scouller, with whom he had seven children. He served on Tambo Shire Council from 1888 to 1892 (president 1885–86, 1890–91) and on Orbost Shire Council from 1892 to 1902 (president 1892–93). In 1902 he won a by-election for the Victorian Legislative Assembly seat of Gippsland East. He moved the no-confidence motion against the Bent government in 1908, and was a minister without portfolio from 1909 to 1913. Later a Nationalist, he held his seat until 1920, when he was defeated by a Victorian Farmers' Union candidate. Cameron died in Orbost in 1922.

Example Input: Question: What is the birthplace of the man who revealed that Trnka was the composer of works previously attributed to Mozart? Passage:Trnka emerged into public view in 1988 when it was revealed by Wolfgang Plath that he was the composer of two minor works previously attributed to Wolfgang Amadeus Mozart. Trnka's compositional specialization appears to have been canons, a form of music at the time often sung recreationally among friends. According to Link, at least 61 canons by Trnka survive, and all but one are to lyrics by the famous librettist Metastasio. Mozart enjoyed singing canons with his friends (see "Difficile lectu"), and particularly liked canons with humorous scatological lyrics, of which he composed several himself (see Mozart and scatology). In the present case, Mozart evidently took two canons by Trnka and gave them new lyrics, which he probably wrote himself. Trnka's "Tu sei gelosa, è vero" became Mozart's "Leck mir den Arsch fein recht schön sauber" ("Lick me in the ass right well and clean"), and Trnka's "So che vanti un cor ingrato" became Mozart's "Bei der Hitz im Sommer eß ich" ("In the heat of summer I eat"). These works were mistaken as Mozart's compositions when his widow Constanze sent them as part of a bundle of canons in 1800 to the publisher Breitkopf & Härtel, who four years later duly published them as Mozart's work. They entered the standard Köchel catalogue as K. 233 and K. 234 (K 382e).
