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: How old was the Antartic's commander when he dropped Otto's party off at a small island? Passage:He led the 1901-1904 Swedish Antarctic Expedition, aboard the ship Antarctic. The expedition visited the Falkland Islands before the ship, commanded by seasoned Antarctic sailor Carl Anton Larsen, dropped Nordenskjold's party off at Snow Hill Island, a small island off the coast of the Antarctic Peninsula. Nordenskiold overwintered at Snow Hill Island, while Antarctic returned to the Falklands. The following summer Larsen brought her south, intending to retrieve the Nordenskiold party, but she became trapped in ice which eventually crushed her hull, forcing Larsen and his crew to overwinter in a hastily constructed shelter on Paulet Island. Larsen and Nordenskjold finally rendezvoused at their fall-back rescue hut at Hope Bay in late 1903, where they were picked up by the Argentine Navy corvette ARA Uruguay (commanded by Julian Irizar), which had been dispatched when Antarctic had failed to make her appointed return to South America the previous year. Despite its end and the great hardships endured, the expedition was considered a scientific success, with the parties having explored much of the eastern coast of Graham Land, including Cape Longing, James Ross Island, the Joinville Island group, and the Palmer Archipelago. The expedition, which also recovered valuable geological samples and samples of marine animals, earned Nordenskjold lasting fame at home, but its huge cost left him greatly in debt.
