Question: Which town was near the camp that, until May 1942, the Germans used it to mostly kill off Jews from Belgrade and other parts of Serbia? Passage 1:William Alfred Passavant was born in 1821 in Zelienople, Pennsylvania, the third and youngest son of Phillipe Louis Passavant and Fredericka Wilhelmina Basse (nicknamed "Zelie," hence the town's name). His grandfather, Baron Dettmar Basse, born in Iserlohn in the Ruhr Valley in what was then the Grand Duchy of Hesse and later became Germany, spent a decade in Paris as a diplomat and merchant before fleeing the Napoleonic Wars and emigrating to Philadelphia and then Pittsburgh in 1801. Drawn by the prospect of religious freedom and economic opportunity, the widower Baron bought 10,000 acres along Connoquenessing Creek in Butler County, Pennsylvania, began building a wood framed castle, and founded (with Christian Buhl) a new town complete with sawmill, brickyard, and an iron furnace. He also traveled and sent glowing letters back to Germany, persuading his daughter and her new husband (a French Huguenot who fled after repeal of the Edict of Nantes) to emigrate in 1807 from Frankfurt.
 Passage 2:The 1st King's Dragoon Guards was a cavalry regiment in the British Army. The regiment was raised by Sir John Lanier in 1685 as the 2nd Queen's Regiment of Horse, named in honour of Queen Mary, consort of King James II. It was renamed the 2nd King's Own Regiment of Horse in 1714 in honour of George I. The regiment attained the title 1st King's Dragoon Guards in 1751. The regiment served as horse cavalry until 1937 when it was mechanised with light tanks. The regiment became part of the Royal Armoured Corps in 1939. After service in the First World War and the Second World War, the regiment amalgamated with the 2nd Dragoon Guards (Queen's Bays) in 1959 to form the 1st The Queen's Dragoon Guards.
 Passage 3:After the April war of 1941 when Germany and its allies occupied and partitioned the Kingdom of Yugoslavia, entire Syrmia region (including the left bank of the Sava) became part of the Independent State of Croatia where they set the Ustaše regime. Nazi secret police, Gestapo, took over Sajmište. They encircled it with several rings of barbed wire turning it into what they referred to as "collection center" – a euphemism for a prison. It eventually became a concentration camp. Until May 1942 Germans used Sajmište concentration camp to mostly kill off Jews from Belgrade and other parts of Serbia. From April 1942 onwards, Serbian prisoners were transported in from Jasenovac and Stara Gradiška concentration camps run by ISC Croatian Ustaše. Partisans captured throughout Serbia were also sent to Sajmište. Detainees were also sent in from other parts of Yugoslavia, especially Serbs after major German offensives on briefly liberated territories. Executions of captured prisoners lasted as long as the camp existed. During their heavy “Easter bombing” of Belgrade, Allied aircraft bombed Sajmište on 17 April 1944, killing some 100 inmates and inflicting heavy damage on the camp itself, destroying all the buildings except for the Spasić pavilion and the Central tower..

Question: What is the highest level of mics? Passage 1:Yet again, Town's season was dominated by their FA Cup run. They reached their fifth and so far last FA Cup Final. After a win over Hull City in Round 3, they scraped past Notts County and Liverpool, they beat York City in the quarter-final in a replay, before beating the favourites Sunderland at Ewood Park in the semi-final, meaning they would play Preston North End in the final, a repeat of the 1922 FA Cup Final, the only one of Town's previous final appearances that they won. The final at Wembley was the first since moving to the London stadium to go into extra time. The result would be the opposite to the 1922 final, with Town conceding a penalty to lose the match 1–0.
 Passage 2:In 1994, he was introduced to Erick Sermon of EPMD by his friend K-Solo. Sermon included Murray on his album No Pressure on the single "Hostile", with critics praising Murray's lyrical ability. His appearance on Hostile led to Murray being signed to Jive Records, and work began on his first album. Murray's debut single, The Most Beautifullest Thing in This World was released in 1994 and was a hit. The song was produced by Erick Sermon (who also provided background vocals) and peaked at number 50 on the Billboard 200 and number 3 on the Hot Rap Singles chart. Murray's debut album The Most Beautifullest Thing in This World, was named after the single and released in 1994 to widespread critical acclaim and commercial success, being certified Gold by the Recording Industry Association of America (RIAA) in August 1995. The album was also given 4 mics by The Source. Murray continued to enjoy a high media-profile by appearing on a Coca-Cola advertisement and as a featured guest on Mary J Blige’s Be Happy, Total’s Can’t You See, R Kelly's Home Alone and LL Cool J’s I Shot Ya.
 Passage 3:Von Maillinger was born in Passau. After passing his company officer career, at last in the Generalquartiermeister staff in Munich, he was transferred to the General Command in Munich as major of the general staff. The first time, he served for the war ministry, he was ordered by Von Lüder. In 1863 he became head of department at the war ministry. Also he was adjutant of Eduard von Lutz, as well as representative of him at the Landtag. In 1865 he was advanced to Oberstleutnant, in 1866 he Oberst. Thenceforward he was commander of the 7th Royal Bavarian Infantry Regiment and deputy of Von Lutz. In 1869 he became major general and commander of the 8th Royal Bavarian Infantry Brigade. One year after that, he was advanced to lieutenant general, and led the 2nd Royal Bavarian Division during the campaigns of the Franco-Prussian War, which stood in France as part of the Bavarian occupation army until 1873. After he returned to Bavaria, he became commander of the II Royal Bavarian Corps. During the period, when he served as war minister, he was advandced to General der Infanterie in 1877 and got the main ownership of the 9th Royal Bavarian Infantry Regiment "Wrede" The psychiatrist and neurologist Prof. Dr. Dr. Dres. h.c. Heinz Häfner says, Maillinger's withdrawal from his ministry post was caused by Ludwig II's reputed sexual abuse of young cavalrists (chevau-légers). Ritter von Maillinger became a member of the Reichsrat in 1888. He died in Bad Aibling. The Maillingerstraße in Munich is named in honor of him.

Question: What country is Dublin located? Passage 1:Margaret Brady was born on 12 February 1857 in Dublin and was baptised in St. Lawrence O'Toole's parish. At that time, her parents were living at 1, Clarence Street. Her father was Patrick Brady, a coal merchant, whose family were from County Meath and her mother was Brigid Brady (née Savage) of Oldtown, Co. Dublin. Margaret's great grandfather Walter Brady was from Nobber in Meath but was originally a Cavan man by birth. His son Walter, Margaret's grandfather, married Margaret O'Connor and had eight children – Catherine, Phil, Anne, Patrick, Larry, Christie, John and Margaret (Aunt). Patrick Brady, her father, married Brigid Savage, a Fingal woman who was the best step dancer of her day in the North County. Margaret had three known siblings, Walter who died as an infant in 1855, as did Brigid in 1860. Another sister, Catherine, died in 1888 leaving a young family behind. Margaret was educated by the Sisters of St Vincent de Paul. She was employed as a stationery shop assistant where she met her future husband, James Pearse.
 Passage 2:Mullane's no-hitter for the Louisville Eclipse was nearly derailed in the ninth inning, however; with two out, Pop Snyder of the Cincinnati Red Stockings lofted a fly ball to center field, but John Reccius mishandled what should have been an easy catch. Snyder, now on first base, complained to Walsh that Mullane was bringing his arm above his shoulder when pitching, which was not permitted at the time. Walsh overruled the complaint, however, and Mullane got Dan "Ecky" Stearns to ground out to end the game. The game was also notable for another incident in the eighth inning; the American Association's rules at that time permitted a substitute to run for a batter who was injured, as long as both teams' captains consented, with the substitute standing behind home plate and prepared to run if the hitter made contact. Pete Browning, who had a pulled leg muscle and had not reached base in the game, batted what appeared to be a single into right field, but forgot the presence of the substitute (Hecker) and ran to first base as Hecker stopped in surprise. Snyder, the Cincinnati catcher, had pitcher Will White throw the ball to Stearns at first base, and Walsh immediately signaled an out, ruling that Hecker was the correct runner and had not reached first. The lost hit eventually resulted in Browning's final career batting average being .341 rather than .342; the higher average would have tied him with Dan Brouthers for the highest mark among players of the era before , when the pitching distance was extended from 50 to 60'6".
 Passage 3:Archibald Magill Fauntleroy (b. in Warrenton, Virginia, 8 July 1837; d. in Staunton, Virginia, 19 June 1886) was a physician. He graduated in medicine at the University of Pennsylvania in 1856, and in 1857 entered the United States Army as assistant surgeon; but, upon the start of the Civil War, he and his brother, a lieutenant in the navy, resigned at the same time with their father, Thomas T. Fauntleroy. He became a surgeon in the Confederate army, and was president of the board for the admission of surgeons, and chief officer on the medical staff of Gen. Joseph E. Johnston, and served with him until the battle of Seven Pines. He was then ordered to build and organize the hospitals at Danville, Virginia, and afterward had charge of the military hospital at Staunton, Virginia, until the war ended. He remained and practised at Staunton after the war, and was for several years superintendent of the lunatic asylum at that place. His contributions to medical literature include papers on potassium bromide, chloral hydrate, the use of chloroform in obstetrical practice, and a “Report upon Advance in Therapeutics,” which was printed in the Transactions of the Virginia Medical Society.
