In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as 'a' for Yes or 'b' for No.

Example Input: Question: Was Carlos Manuel still alive when Batista was elected President of Cuba? Passage:Fulgencio Batista y Zaldivar (; ; born Ruben Zaldivar; January 16, 1901 August 6, 1973) was a Cuban military officer and politician who served as the elected President of Cuba from 1940 to 1944, and as its U.S.-backed military dictator from 1952 to 1959, before being overthrown during the Cuban Revolution. Batista initially rose to power as part of the 1933 Revolt of the Sergeants, which overthrew the provisional government of Carlos Manuel de Cespedes y Quesada. He then appointed himself chief of the armed forces, with the rank of colonel, and effectively controlled the five-member "pentarchy" that functioned as the collective head of state. He maintained this control through a string of puppet presidents until 1940, when he was himself elected President of Cuba on a populist platform. He then instated the 1940 Constitution of Cuba and served until 1944. After finishing his term he lived in Florida, returning to Cuba to run for president in 1952. Facing certain electoral defeat, he led a military coup against President Carlos Prio Socarras that preempted the election.

Example Input: Question: How old was the person who broke King's record in 1925? Passage:In April 1914 he joined Arsenal for a 1,000 fee, returning to League football. Arsenal had just missed out on promotion on goal average to the First Division, and in 191415 King spearheaded their attack, scoring 26 goals in the League and another three in the FA Cup. These included the first hat trick scored at their new Highbury stadium (against Grimsby Town on 14 November 1914), and two four-goal hauls against Wolverhampton Wanderers and Nottingham Forest. King's 29 goals that season were an all-time club record at the time, remaining so until Jimmy Brain broke it in 192526. However, Arsenal's defence let them down and they only finished fifth, outside of the promotion places; eventually, they were re-elected back to the First Division when football resumed after the end of the First World War.

Example Input: Question: Was his mother still alive when Benigno Simeon Aquino III took the oath? Passage:By tradition, it is also the chief justice who swears into office the President of the Philippines. One notable deviation from that tradition came in 1986, and later again in 2010. Due to the exceptional political circumstances culminating in the People Power Revolution, on February 25, 1986, Corazon Aquino took her oath of office as President before then Associate Justice Claudio Teehankee in San Juan just minutes before Ferdinand Marcos took his own oath of office also as President before Chief Justice Ramon Aquino. Marcos fled into exile later that night. More than two decades afterwards, Benigno Simeon Aquino III followed in his mother's footsteps (with almost similar reasons) by having then Associate Justice Conchita Carpio-Morales to administer his oath of office, rather than then Chief Justice Renato Corona (who was eventually impeached halfway through Aquino's term). Six years later, in 2016, Rodrigo Duterte took his oath of office before Associate Justice Bienvenido Reyes, his classmate at San Beda College of Law, instead of Chief Justice Maria Lourdes Sereno (who would eventually be removed thru quo warranto after it was determined that she had been unlawfully holding office ab initio).
