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: Was the #11 seed school that made it to their first Final Four appearance a private school? Passage:The 2011 NCAA Men's Division I Basketball Tournament was the first time since the tournament expanded to 64 teams in 1985 that two mid-majors met in the Final Four. The Butler University Bulldogs returned for their second consecutive appearance after winning the Southeast Regional in New Orleans as a #8 seed. The Virginia Commonwealth University Rams of the Colonial Athletic Association advanced to their first Final Four appearance after winning the Southwest Regional in San Antonio as a #11 seed. VCU became the first team in history to win five games to reach the Final Four, winning the First Four round in its inaugural year. VCU tied LSU in 1986 and fellow CAA team, George Mason, in 2006 as the highest seed to reach the Final Four (#11). The previous time two mid-majors advanced to the same Final Four was the 1979 NCAA Men's Division I Basketball Tournament, when Indiana State of the Missouri Valley and Penn of the Ivy League qualified. Butler is no longer a mid-major due to its membership in the Big East since 2013. VCU has since joined the Atlantic 10, where it has consistently been among the top teams, even following the departure of coach Shaka Smart for Texas in 2015, and his successor, Will Wade, for LSU in 2017.

Example Input: Question: What man was the lead guitarist for the shortest amount of times? Passage:The Yardbirds are an English blues rock band from London. Formed in May 1963, the group originally included lead vocalist Keith Relf, lead guitarist Anthony "Top" Topham, rhythm guitarist Chris Dreja, bassist Paul Samwell-Smith and drummer Jim McCarty. In October, Topham was replaced by Eric Clapton. He remained until 13 March 1965, when he left due to creative disagreements. Clapton recommended Jimmy Page to replace him, but he declined and Jeff Beck took over. Page later joined on bass the following June, after Samwell-Smith abruptly quit; Dreja later took over the role, allowing Page to join Beck on guitar. This lineup was short-lived, however, as Beck left in November 1966. The group continued as a four-piece until July 1968, when Relf and McCarty left due to creative differences, primarily with Page. Dreja initially remained, but by August Page formed a new group with vocalist Robert Plant, bassist John Paul Jones and drummer John Bonham, who later renamed themselves Led Zeppelin.

Example Input: Question: What year was the team that Pemberton made his debut against founded? Passage:Brock Pemberton (November 6, 1953 February 17, 2016) was a Major League Baseball player, who played for the New York Mets in 1974 and 1975. He also played in the St. Louis Cardinals' organization. He played as a first baseman. Pemberton played high school baseball in Huntington Beach, California and was drafted by the Mets in the 6th round of the 1972 June Amateur Draft. After playing in the lower minor leagues in 1972 and 1973, he was promoted to AA level with the Victoria Toros of the Texas League in 1974. That year, he posted a .322 batting average in 134 games and 482 at bats for the Toros. He also had 8 home runs. This performance earned Pemberton a promotion to the Major League Mets late in the season. Pemberton made his debut with the Mets as a pinch hitter on September 10, 1974, against the Montreal Expos. The next day, the Mets and St. Louis Cardinals played a 25 inning game in which Pemberton got his first Major League hit, also as a pinch hitter. In all, he played 11 games for the Mets in 1974, with 4 hits in 22 at-bats and one run batted in. In four games as a first baseman he did not make an error.
