[EX Q]: 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..

[EX Q]: Question: Is the racecourse where Roaring Riva began his racing career at and the location where he moved up in class for Group 1 Phoenix Stakes located in the same country? Passage 1:Emanuel Nobel was a very forward-looking businessman, just like his father, who had instigated the construction of Russia's first pipeline and the world's first oil tanker in 1878, as well as the world's first railway tank cars in 1883. On 16 February 1898 Emanuel signed a licence agreement in Berlin with Rudolf Diesel, after having heard Diesel describing his new engine in a public lecture. The agreement allowed Nobel to build the world's first diesel engine plant in St Petersburg, and the engines were used to propel Branobel's fleet of oil tankers. Emanuel led Baku to a dominating role in the global oil industry and Branobel activities soon developed throughout the Caspian Sea, operating also in Grozny and Dosser.
 Passage 2:Dean Clark took over as head coach shortly after James' resignation, and led the 1997–98 Hitmen to a remarkable turnaround. The team improved to a 40–28–4 record and first-place finish in the Central Division, qualifying for the playoffs for the first time in franchise history. They defeated the Saskatoon Blades and Swift Current Broncos to reach the Eastern Conference final before falling to the Brandon Wheat Kings. Clark was awarded the Dunc McCallum Memorial Trophy as the WHL's top coach, and also won the Canadian Hockey League's Brian Kilrea Coach of the Year Award. Calgary improved to 51–13–8 in 1998–99, finishing one point ahead of the Kamloops Blazers for the regular season title. Led by Brad Moran, Pavel Brendl and goaltender Alexandre Fomitchev, the Hitmen lost just five games in the playoffs en route to their first league championship. They won the title at home before a WHL playoff record crowd of 17,139. They became the first Calgary-based team to qualify for the Memorial Cup since the Calgary Canadians won the 1926 title.
 Passage 3:Roaring Riva began his racing career by winning a maiden race over five furlongs at Windsor Racecourse and then followed up by taking a minor event over six furlongs at the same track. In early July he was sent to York Racecourse to contest the Black Duck Stakes and finished second, beaten half a length by Nomination, a colt who went on to beat Green Desert in the Richmond Stakes. The colt was then sent to Ireland and moved up in class for the Group 1 Phoenix Stakes over six furlongs on soft ground at Phoenix Park Racecourse. Ridden by Ray Cochrane he started the 4/1 second favourite behind the highly regarded, but previously unraced Tate Gallery, with the best-fancied of the other eleven runners being the unbeaten filly Sherkraine, Devil's Run and Mr John. Roaring Riva was among the leaders from the start, went to the front two furlongs out and held off the challenge of the filly So Directed to win by three quarters of a length. Laing recalled that it was "quite a day. We had private planes, champagne, the lot!"

[EX Q]: Question: Did the Houston loss in the AAC Tournament happen before their first round defeat in the NIT? Passage 1:On April 3, 2014, Houston hired Kelvin Sampson as the new Cougars head coach. Sampson had just become eligible to be a college coach again after receiving a five-year show cause penalty in 2008 for sanctions against him during his time as Indiana head coach. In 2014–15, Houston struggled again, finishing with a 13–19 record and 4–14 in the AAC. The 2015–16 team led a resurgence, finishing 22–10, 12–6, but lost in the AAC Tournament and in the first round of the NIT. In 2017–18, the Cougars compiled a 27–8 record, reaching the finals of the AAC Tournament and winning a game in the NCAA Tournament for the first time since 1984. In 2018–19, the Cougars' success continued as they set a program record for wins with a 33–4 mark. They were AAC regular-season champions but fell in the finals of the conference tournament. They proceeded to the NCAA Tournament, where they reached the Sweet Sixteen for the first time in 35 years.
 Passage 2:Merlin Jay Olsen (; September 15, 1940 – March 11, 2010) was an American football player, announcer, and actor. He played his entire 15-year professional football career in National Football League (NFL) as a defensive tackle with the Los Angeles Rams. He was selected to the Pro Bowl a record 14 straight times, missing selection only in the last year of his career. This record of 14 seasons selected to play in the Pro Bowl, consecutive or otherwise, is shared with current New England Patriots quarterback Tom Brady, former offensive lineman Bruce Matthews, former tight end Tony Gonzalez, and former quarterback Peyton Manning. A recipient of the 1961 Outland Trophy as the best lineman in college football, Olsen is a member of the Pro Football Hall of Fame and the College Football Hall of Fame. As an actor, he portrayed farmer Jonathan Garvey on Little House on the Prairie. After leaving that series, he starred in his own NBC drama, Father Murphy.
 Passage 3:Pinza sang once again under the baton of Toscanini in 1935, this time with the New York Philharmonic Orchestra, as the bass soloist in performances of Beethoven's Missa Solemnis. One of these performances was broadcast by CBS and preserved on transcription discs; this recording has been issued on LPs and CDs. He also sang in Toscanini's February 6, 1938, NBC Symphony Orchestra's broadcast performance of Beethoven's Ninth Symphony. These performances both took place in Carnegie Hall. In March 1942, Pinza was arrested at his home and unjustly detained 3 months on Ellis Island with hundreds of other Italian-Americans who were suspected of supporting the Axis. The incident was extremely traumatic for Pinza, and he suffered from severe depression for years afterward. In October 1947, he performed the role of Méphistophélès in Guonod's Faust opposite his daughter, soprano Claudia Pinza Bozzolla, as Marguerite at the San Francisco Opera.
