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 of the two countries that the Soviets sent troops to in January 1991 had the larger army? Passage:On 12 May 1990 the leaders of the Baltic republics signed a joint declaration known as the Baltic Entente. By mid-June the Soviets started negotiations with the Baltic republics on condition they agreed to freeze their declarations of independence. The Soviets had a bigger challenge elsewhere, in the form of the Russian Federal Republic proclaiming sovereignty in June. Simultaneously the Baltic republics also started to negotiate directly with the Russian Federal Republic. In Autumn 1990, they set up a customs border between the Baltic states, the Russian Federation and Belarus. After the failed negotiations the Soviets made a dramatic attempt to break the deadlock and sent troops to Lithuania and Latvia in January 1991. The attempts failed, dozens of civilians were killed, and the Soviet troops decided to retreat. In August 1991, the hard-line members of the Soviet government attempted to take control of the Soviet Union. One day after the coup on 21 August, the Estonians proclaimed independence. Shortly afterwards Soviet paratroops seized the Tallinn television tower. The Latvian parliament made similar a declaration at the same day. The coup failed but the Collapse of the Soviet Union became unavoidable. On 28 August, the European Community welcomed the restoration of the sovereignty and independence of the Baltic states. The Soviet Union recognised the Baltic independence on 6 September 1991. The Russian troops stayed for an additional three years, as Boris Yeltsin linked the issue of Russian minorities with troop withdrawals. Lithuania was the first to have the Russian troops withdrawn from its territory in August 1993. On 26 July 1994 Russian troops withdrew from Estonia and on 31 August 1994, Russian troops withdrew from Latvia. The Russian Federation ended its military presence in Estonia after it relinquished control of the nuclear facilities in Paldiski on 26 September 1995 and in Latvia after Skrunda-1 suspended operations on 31 August 1998 and subsequently dismantled. The last Russian soldier left Skrunda-1 in October 1999, thus marking a symbolic end to the Russian military presence on the soil of the Baltic countries.

Example Input: Question: Who is the current owner of the team founded by  Art Rooney? Passage:The Arizona Cardinals National Football League (NFL) franchise is allegedly suffering a curse by the citizens of Pottsville, Pennsylvania for undeservedly claiming the 1925 NFL championship from the Pottsville Maroons who were stripped of their title by the NFL in one of the greatest controversies in sports history. The curse will supposedly only be lifted when the championship is returned to Pottsville and to the correct shade of red team; this can only be met by overturning the original ruling, as Pottsville no longer has an NFL team and is too small to ever receive another one (with a metropolitan area roughly half the population of Green Bay, the league's smallest), making it impossible for the long-defunct Maroons to win another title. The Cardinals team holds the record for the longest championship drought, with their most recent championship coming in 1947, which is also the longest drought in American professional sports; the 1947 team was notable for having two of its members die during their playing careers within a year of each other, with Jeff Burkett dying in a plane crash following appendix surgery during the season and Stan Mauldin dying of a heart attack after a game the following season. Arizona also lost Super Bowl XLIII to another Pennsylvania team: the Pittsburgh Steelers (whose founder Art Rooney supported Pottsville's claim to the title). The franchise also leads the NFL in the total number of losses (730 through the 2017 season).

Example Input: Question: Are the winds higher in a squall or in a gale? Passage:Shovell's fleet of twenty-one ships left Gibraltar on 29 September, with serving as his own flagship, HMS Royal Anne as flagship of Vice-Admiral of the Blue Sir George Byng and as flagship of Rear-Admiral of the Blue Sir John Norris. The passage was marked by extremely bad weather and constant squalls and gales. As the fleet sailed out on the Atlantic, passing the Bay of Biscay on their way to England, the weather worsened and storms gradually pushed the ships off their planned course. Finally, on the night of 22 October 1707 Old Style, (2 November 1707 by the modern calendar), the squadron entered the mouth of the English Channel and Shovell's sailing masters believed they were on the last leg of their journey. The fleet was thought to be sailing safely west of Ushant, an island outpost off the coast of Brittany. However, because of a combination of the bad weather and the mariners' inability to accurately calculate their longitude, the fleet was off course and closing in on the Isles of Scilly instead. Before their mistake could be corrected, the fleet struck rocks and four ships were lost:
