question:
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.

Passage: The first obelisks may start to appear in the later 16th century and it is suggested that the obelisk on Compton Pike is Elizabethan in date. More securely dated is a series of obelisks which start to appear in the 18th century. The first of these was the Wakeman obelisk of 1702 by Nicholas Hawksmoor, which is set in the square at Richmond, Yorkshire. Probably several hundred obelisks exist in the British Isles dating from 18th and early 19th centuries. Most of these obelisks, which are often landmarks commemorate famous people and their achievements. At Stowe in Buckinghamshire an obelisk was erected in memory of Wolfe's victory at Quebec in 1752, while at the death of the Duke of Cumberland in 1765 was noted by an obelisk at Englefield Green in Surrey. Thomas Coke, Earl of Leicester, Coke of Norfolk the farming pioneer has a particularly fine obelisk, set up in the park he created at Holkham in Norfolk. Sometimes an obelisk was used to mark the site of a battle such as the obelisk on the site of English Civil War battlefield at Naseby in Leicestershire. Occasionally obelisks are used as mile markers, as on the Great North Road at a mile from Westminster. In Lincoln an elaborate obelisk was set up on the High Bridge in 1762–63 as a conduit for dispensing water, while Anthony Salvin used obelisks as water fountains on the Belton House estates in Lincolnshire.

question:
Passage: Spindler was born in Łódź, Poland, to an ethnic German family. He was the son of Gertrud Alma (née Bernewitz) and Oskar Karl Spindler; his father was a businessman. Spindler was considered part of the Volksdeutsche by the Nazi regime, and after the German invasion of Poland in 1939 was required to join the Deutsches Jungvolk (part of the Hitler Youth). When Germany's Eastern Front collapsed in 1944, Spindler and other children of Łódź were evacuated to a rural estate north of the city. In January 1945, he and his companions were forced to flee west on foot to escape the advancing Red Army; many of them were killed by starvation, exposure, or bombing raids. Spindler was eventually reunited with his family in Magdeburg, and they settled in Weißenfels, Saxony-Anhalt, which became part of the Soviet occupation zone and later East Germany. He was blacklisted from attending university due to his anti-Soviet views, and at the age of 17 was granted permission to move to Australia, sponsored by a relative who had settled in Melbourne.
