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 many years were there between the re-forming of the 20 Battery Royal Artillery and the beginning of the Cuban missile crisis? Passage:After the Second World War the Battery was re-formed in 1955 as 20 Medium Battery as part of 21 Med Regt based at Redford Barracks, Edinburgh but deployed in the Internal Security role to Cyprus in 1956 where the Regt lost several men to the EOKA terrorists. Re-numbered again and re-rolled (a change of equipment and role) as an Amphibious Operations (AO) Battery. They were posted to Hong Kong and renamed 20 Commando (AO) Battery as part of 29 Commando Regiment. Due to the fact that only 20 and 148 Commando (AO) Battery fulfilled the AO roll there was a lot of movement between the batteries most men serving in both. The battery had absorbed 3 (AO) Troop on their move to Hong Kong and was involved in a number of operations including the Korean War and a little known operation in the Caribbean during the Cuban missile crisis. The Battery was involved in clearing Russian, American and Cuban personnel off remote Caribbean islands in the region and arrested 60 men who later turned out to be CIA operatives, causing a minor political incident. The Battery was placed into suspended animation in 1969 following the downsizing of the British Army and the reduction to one Commando Artillery Regiment, having lost out to 148 Commando (AO) Battery. Many of 20 Commando (AO) Battery's personnel ended up in 148 Battery and so did much of the battery property.

Example Input: Question: Who is the current office holder of the position that Clinton held from 1977 to 1979? Passage:William Jefferson Clinton (born William Jefferson Blythe III; August 19, 1946) is an American politician who served as the 42nd president of the United States from 1993 to 2001. Prior to his presidency, he served as governor of Arkansas (1979–1981 and 1983–1992) and as attorney general of Arkansas (1977–1979). A member of the Democratic Party, Clinton was known as a New Democrat, and many of his policies reflected a centrist "Third Way" political philosophy. He is the husband of former Secretary of State and former U.S. Senator Hillary Clinton. In 1998, Clinton was impeached by the House of Representatives. The impeachment was based on accusations that Clinton committed perjury and obstruction of justice for the purpose of concealing his affair with Monica Lewinsky, a 22-year-old White House intern. He was acquitted by the Senate and completed his term in office. Clinton is notable as one of only two U.S. presidents (following Andrew Johnson 130 years earlier) to have been impeached.

Example Input: Question: Who did Manuel's uncle run against for the mayorship of Ciales? Passage:Natal was born into a family with strong ties to the local politics. His maternal uncle, Javier Albelo Matos, served as a candidate for the mayorship of Ciales the 2000 general election, while his paternal grandfather was an activist for the Partido Popular Democratico (PPD). He studied at Colegio Espíritu Santo in Hato Rey, where he was president of the Student Council. Natal obtained a bachelor's degree from Cornell University in 2008, where he was president of the Puerto Rican Student Association. He did not expect to be accepted by the institution, having applied to study in it as a protocolary measure. When the acceptance letter was received, Natal was surprised and this event triggered a period of adaptation. He offered a speech at his graduation in his role of class president. After returning to Puerto Rico, Natal received a juris doctor from the University of Puerto Rico School of Law in 2011, also serving as president of the student council during his tenure. After graduating from Cornell, Natal became a key figure in a series of strikes held at the University of Puerto Rico in protest of a quota being introduced to the students. Consequently he became involved with the Popular Democratic Party and participated in an internal election for the presidency of the party's National Youth organization. After completing his juris doctor Natal opened his own lawfirm and worked for Charlie Hernández and Luis Vega Ramos, prominent members of the free association movement. In 2013, Natal was named director of the House of Representatives of Puerto Rico Commission on the Judiciary.
