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: Who had the best record during the period that Barnsley F.C.  played in the Sheffield & District League? Passage:Barnsley Football Club is an English association football club based in the South Yorkshire town of Barnsley. Founded in 1887 under the name Barnsley St Peter's, the team played in the Sheffield & District League from the 1890–91 season and first entered the FA Cup in 1893–94. Two years later, they were accepted into the Midland League. The club changed its name to Barnsley F.C. in 1897; its team finished as Midland League runners-up in the first season under the new name, and were elected to the newly expanded Second Division of the Football League for the 1898–99 season. A 16th-place finish in their second season meant they had to apply for re-election; the application was successful, and Barnsley continued safely in mid-table until 1911, when they again needed to be re-elected to the League. Their cup form was rather better: either side of that poor League placing, they reached the FA Cup final. In 1909–10, they drew 1–1 with Newcastle United in the final at Crystal Palace, but lost 1–0 in the replay at Everton's Goodison Park ground. Two seasons later, after taking three replays to get through the quarter-final, they played out a goalless draw with West Bromwich Albion at Crystal Palace; this time Barnsley won the replay, at Sheffield United's Bramall Lane ground, by one goal to nil.

Example Input: Question: What was John Holt's career? Passage:Youth activism as a social phenomenon in the United States truly became defined in the mid- to late-nineteenth century when young people began forming labor strikes in response to their working conditions, wages, and hours. Mary Harris "Mother" Jones organized the first youth activism in the U.S., marching 100,000 child miners from the coal mines of Pennsylvania to the U.S. Capitol in Washington, D.C. in 1908. Youth newspaper carriers soon followed. These actions isolated youths' interests in the popular media of the times, and separated young people from their contemporary adult labor counterparts. This separation continued through the 1930s, when the American Youth Congress presented a "Bill of Youth Rights" to the US Congress. Their actions were indicative of a growing student movement present throughout the US from the 1920s through the early 1940s. The 1950s saw the Student Nonviolent Coordinating Committee bring young people into larger movements for civil rights. All the way back in 1959, Rev. Dr. Martin Luther King, Jr. engaged youth activists in protesting against Bull Connor's racist law enforcement practices in Birmingham, Alabama. The youth activism of Tom Hayden, Keith Hefner and other 1960s youth laid a powerful precedent for modern youth activism. John Holt, Myles Horton and Paulo Freire were important in this period. Youthful life and expression defined this era.

Example Input: Question: Which of the nearby counties of the "Tennessee Valley"  has the largest population?  Passage:According to the United States Census 2013 estimate, the combined statistical area has a population of 1,313,105. It is the 42nd largest population sub-region in the United States, and the largest population region in Alabama, constituting roughly 1/4 of the state's population. It is the largest population region in Central Alabama. The northern counties of the metropolitan area overlap North Alabama known locally as the "Tennessee Valley" making it the largest metropolitan area in that region as well. Nearby counties Tuscaloosa, Etowah, and Calhoun, while not officially a part of Greater Birmingham, contribute significantly to the region's economy. The Birmingham media market covers these counties as well. Birmingham is part of the Piedmont Atlantic Megaregion containing an estimated 19 million people, while many residents also consider themselves part of the Deep South. It is classified as Southeast by the U.S. Census and also falls in the geographic area of the Upland South due to its location at the southern terminus of the Appalachian foothills. The entire MSA and CSA are within the congressional Appalachian Regional Commission's definition of Appalachia.
