[EX Q]: Question: Which of the European kings who support the Charlemagne Prize is the oldest? Passage 1:The Charlemagne Prize (; full name originally Internationaler Karlspreis der Stadt Aachen, International Charlemagne Prize of the City of Aachen, since 1988 Internationaler Karlspreis zu Aachen, International Charlemagne Prize of Aachen) is a prize awarded for work done in the service of European unification. It has been awarded annually since 1950 by the German city of Aachen. It commemorates Charlemagne, ruler of the Frankish Empire and founder of what became the Holy Roman Empire, who resided and is buried in Aachen. Traditionally the award is given to the recipient on Ascension Day in a ceremony in the town hall of Aachen. In April 2008, the organisers of the Charlemagne Prize and the European Parliament jointly created a new European Charlemagne Youth Prize, which recognises contributions by young people towards the process of European integration. Patrons of the foundation are King Philippe of Belgium, King Felipe VI of Spain, and Henri, the Grand Duke of Luxembourg.
Passage 2:Paul of Tammah departed on 7 Paopi (October 17, 415 AD). He was buried along with Saint Pishoy in the Monastery of Saint Pishoy at Deir El Barsha, which still exists today near Mallawi. On 4 Koiak 557 AM (December 13, 841 AD), Pope Joseph I fulfilled the desire of Saint Pishoy and moved his body as well as that of Saint Paul of Tammah to the Monastery of Saint Pishoy in the wilderness of Scetes. It is said that they first attempted to move the body of Saint Pishoy only, but when they carried it to the boat on the Nile, the boat would not move until they brought in the body of Saint Paul of Tammah as well. Today, the two bodies lie in the main church of the Coptic Orthodox Monastery of Saint Pishoy in the Nitrian Desert.
Passage 3:For the Republicans, businessman and candidate for the U.S. Senate in 2014 Matt Bevin ran on a ticket with Tea Party activist and 2014 State House candidate Jenean Hampton; Agriculture Commissioner of Kentucky James Comer ran on a ticket with State Senator Christian McDaniel; former Louisville Metro Councilman and nominee for Mayor of Louisville in 2010 Hal Heiner ran on a ticket with former Lexington-Fayette Urban County Councilwoman and nominee for Kentucky State Treasurer in 2011 K.C. Crosbie; and former Associate Justice of the Kentucky Supreme Court Will T. Scott ran on a ticket with former Menifee County Sheriff Rodney Coffey. Bevin held an 83-vote lead over Comer in the primary election, with both Heiner and Scott conceding. The Associated Press, referring to the race between Bevin and Comer a "virtual tie", did not called the race in favor of either candidate. In addition, Comer refused to concede and stated that he would ask for a recanvass. The request for recanvass was filed with the Kentucky Secretary of State's office on May 20, 2015 with Secretary of State Alison Lundergan Grimes ordering the recanvass to occur at 9:00a.m. local time on Thursday, May 28, 2015. Upon completion of the recanvass, Grimes announced that Bevin remained 83 votes ahead of Comer. Grimes also stated that should Comer want a full recount, it would require a court order from the Franklin Circuit Court. On May 29, Comer announced he would not request a recount and conceded the nomination to Bevin.

[EX Q]: Question: What was the age of the oldest member (besides Stephanie) of the group representing Armenia in the Eurovision Song Contest 2015? Passage 1:Chemokine receptors are G protein-coupled receptors containing 7 transmembrane domains that are found predominantly on the surface of leukocytes, making it one of the rhodopsin-like receptors. Approximately 19 different chemokine receptors have been characterized to date, which share many common structural features; they are composed of about 350 amino acids that are divided into a short and acidic N-terminal end, seven helical transmembrane domains with three intracellular and three extracellular hydrophilic loops, and an intracellular C-terminus containing serine and threonine residues that act as phosphorylation sites during receptor regulation. The first two extracellular loops of chemokine receptors are linked together by disulfide bonding between two conserved cysteine residues. The N-terminal end of a chemokine receptor binds to chemokine(s) and is important for ligand specificity. G-proteins couple to the C-terminal end, which is important for receptor signaling following ligand binding. Although chemokine receptors share high amino acid identity in their primary sequences, they typically bind a limited number of ligands. Chemokine receptors are redundant in their function as more than one chemokine is able to bind to a single receptor.
Passage 2:A return to the Formula Three Euroseries beckoned for van Dam, with a 2009 campaign for Kolles & Heinz Union, the new team set up by Colin Kolles and Werner Heinz. However, the partnership was not to last, as after the rounds at Lausitz, van Dam parted company with the team. In four races, his best finish was eighteenth during the season-opening race at Hockenheim. Van Dam drove in the 24-hour endurance races at the Nurburgring and at Spa, before agreeing to drive the car of PSV Eindhoven in the Superleague Formula series. He replaced Dominick Muermans in the car, with the team lying eighteenth in the overall standings. However, he returned to the Euroseries, for the Barcelona rounds, rejoining his former team SG Formula.
Passage 3:In February 2015 she was announced as a member of the music group Genealogy (made up of singers from Armenia and the Armenian diaspora) that represented Armenia in the Eurovision Song Contest 2015. Stephanie Topalian represents the Asian continent in the formation whereas the Ethiopian Vahe Tilbian represents Africa, the American Tamar Kaprelian the American continent, the French Essai Altounian the European continent and the Australian Mary-Jean O'Doherty Basmadjian Oceania and Inga Arshakyan Armenia. The super group sang "Face the Shadow", the Armenian entry to the 2015 Eurovision Song Contest in Vienna, Austria. She became an Armenian citizen along with the other foreign members of Genealogy on 28 April 2015 after being given Armenian passports by President Serzh Sargsyan.

[EX Q]: 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 (nee 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.
