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: How many franchise locations are there of the place where the Terri Gibbs Trio performed? Passage:Gibbs was born in Miami, Florida, but raised in the Augusta, Georgia, suburb of Grovetown. Although born with eyesight, she lost it as a newborn due to an incubator accident. Despite her blindness, she learned to play piano at age three. As a child, she sang in the church choir and at talent contests, and at age seventeen, she opened for Bill Anderson. Her parents wanted her to be treated no differently from sighted people and she was sent to public school, graduating from Butler High School in Augusta in 1972. She performed in and around the Augusta area and eventually, she met Chet Atkins, who advised her to move to Nashville, Tennessee, to pursue a country music career, which she did at age eighteen. After failing to find a record deal, she returned to Miami and joined a band called Sound Dimension. She continued to perform locally, later forming a band called the Terri Gibbs Trio, which performed at a Steak and Ale in Augusta, Georgia. Gibbs then sent a demo tape to record producer Ed Penney of MCA Records, signing to the label in 1980. Penney was a former Boston disc jockey and a long-time songwriter. He liked her voice on her demo, but felt she needed stronger material. He co-wrote "Somebody's Knockin'" for her and also produced the song.

Example Input: Question: How many wives did Katherine's maternal grandfather have? Passage:Lady Katherine Neville was born in 1442, one of the ten children and the fifth eldest daughter of Richard Neville, 5th Earl of Salisbury and Alice Montacute, suo jure 5th Countess of Salisbury. Her mother was the only child and heiress of Thomas Montacute, 4th Earl of Salisbury by his first wife Lady Eleanor Holland. Katherine's eldest brother was Richard Neville, 16th Earl of Warwick, 6th Earl of Salisbury, also known as "Warwick the Kingmaker". He was the most important and influential peer in the realm, and one of the principal protagonists in the Wars of the Roses. Her aunt, Cecily Neville, Duchess of York, mother of future kings and Katherine's first cousins, Edward IV and Richard III, was another key figure in the dynastic civil wars that dominated most of the latter half of 15th century England. Her niece, Anne Neville (youngest daughter of the "Kingmaker") would become Queen of England as the consort of Richard III; Katherine's sister Alice, Baroness FitzHugh, and her other niece, Elizabeth FitzHugh, were personally selected as Anne's chief ladies-in-waiting. Her paternal grandparents were Ralph Neville, 1st Earl of Westmorland and Joan Beaufort, Countess of Westmoreland, a daughter of John of Gaunt by his third wife, Katherine de Roët, making her a direct descendant of Edward III.

Example Input: Question: How old was the man whose grandson later deposed him? Passage:In 1341, the Byzantine Empire was in a state of turmoil, and despite the restoration of the Empire's capital to Constantinople and the recovery of a measure of its former power by Michael VIII Palaiologos (r. 1259–1282), the policies implemented during his reign had exhausted the state's resources, and the Empire's strength waned under his successor, Andronikos II Palaiologos (r. 1282–1328). During Andronikos II's long reign, the remaining Byzantine possessions in Asia Minor slowly fell to the advancing Turks, most notably the newly established Ottoman emirate. This caused a flood of refugees into Byzantium's European provinces, while at the same time the Catalan Company wrought havoc in the imperial domains. Taxes also rose dramatically to finance tributes to the Empire's enemies. A combination of these failures and personal ambition moved the Emperor's grandson and heir, the young Andronikos III Palaiologos, to revolt. Supported by a group of young aristocrats led by John Kantakouzenos and Syrgiannes Palaiologos, Andronikos III deposed his grandfather after a series of conflicts during the 1320s. Although successful in removing the old Emperor from power, the war did not augur well for the future, as the Empire's neighbours—the Serbs, Bulgarians, Turks, Genoese and Venetians—took advantage of Byzantine infighting to gain territory or expand their influence within the Empire.
