Input: Consider Input: Question: How long had the Algerian war been going on when Kopanski was 14? Passage:In 1962, when only 14, he was fascinated by the success of the Arab national and anti-colonial forces that defeated the French colonial armies in the Algerian War, gaining independence for their country. When attending a military college in Kętrzyn (Ger. Rastenburg) in 1966-1969, he actively opposed the Polish communist regime during the 1968 Polish political crisis, and as a result was expelled from the Officer School, and became a political prisoner for the first time. He continued his studies at the University of Silesia in Katowice, and after graduation was employed there as a lecturer,adiunct and researcher. In 1980-81, when Poland was swept by a wave of anti-communist strikes, and around ten million joined the anti-communist Solidarity trade union, Kopański co-founded a branch of this broad grassroots social movement at the University of Silesia.

Input: Consider 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.

Input: Consider Input: Question: Did Jackson or Banks emerge victories in the Battle that took place on May 23rd? Passage:Banks's division technically belonged to George McClellan despite serving as an independent command in the Shenandoah Valley. On March 14, 1862, President Lincoln issued an executive order forming all troops in McClellan's department into corps. Banks thus became a corps commander, in charge of his own former division, now commanded by Brig. Gen Alpheus Williams and the division of Brig. Gen James Shields, which was added to Banks's command. After Stonewall Jackson was turned back at the First Battle of Kernstown on March 23, Banks was instead ordered to pursue Jackson up the valley, to prevent him from reinforcing the defenses of Richmond. When Banks's men reached the southern Valley at the end of a difficult supply line, the president recalled them to Strasburg, at the northern end. Jackson then marched rapidly down the adjacent Luray Valley, and encountered some of Banks' forces in the Battle of Front Royal on May 23. This prompted Banks to withdraw to Winchester, where Jackson again attacked on May 25. The Union forces were poorly arrayed in defense, and retreated in disorder across the Potomac River and back into Maryland. An attempt to capture Jackson's forces in a pincer movement (with forces led by John Frémont and Irvin McDowell) failed, and Jackson was able to reinforce Richmond. Banks was criticized for mishandling his troops and performing inadequate reconnaissance in the campaign, while his political allies sought to pin the blame for the debacle on the War Department.
