[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 Nürburgring 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 Essaï 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.

[Q]: Question: How many people lived in Nancy the year the Second Armistice at Compiègne was signed? Passage 1:Originally from the small city of Minden in Webster Parish in northwestern Louisiana, Spiva was the son of Hubert Spiva, Sr. (1899-1939), a former foreign correspondent, and the former Lilla Ellenor Stewart (1906–1959), who married in 1929. They operated the Webster Printing Company and the former The Minden Herald and The Webster Review newspapers, forerunners of the Minden Press-Herald. Lilla Spiva, a scion of a prominent Webster Parish family, was a daughter of Minden attorney Daniel Webster Stewart, Sr. (1857-1935), and his wife, the former Alice Leona Reagan (1871-1954). She was a niece of William Green Stewart, a farmer and a former president of the Webster Parish School Board, for whom the since defunct William G. Stewart Elementary School in Minden is named. Another uncle, E. L. Stewart, was a member of the Louisiana House of Representatives at the time of her birth. Known as "Babe", Lilla Spiva managed the papers after her husband's death at the age of forty and was herself publisher and society editor of the Minden Herald and a member of the Louisiana Press Association. On January 23, 1960, the press association posthumously honored her for her journalistic accomplishments. Hubert Spiva is interred at Mount Hope Cemetery in Webb City in Jasper County in southwestern Missouri. Lilla is interred with other Stewart relatives at the historic Minden Cemetery. Spiva's aunt, Lilla's sister, was Mary Amanda Stewart (1903–1994), whom he visited in the Stewart home, later the Farley home, when he returned to his hometown.
 Passage 2:Six units of the French Foreign Legion participated in the Battle of France: the 11th Foreign Infantry Regiment, the 12th Foreign Infantry Regiment, the Reconnaissance Group of the 97th Infantry Division, the 21st Marching Regiment of Foreign Volunteers (21st RMVE), the 22nd Marching Regiment of Foreign Volunteers, and the 23rd Marching Regiment of Foreign Volunteers. The 11th REI defended the northern Inor Wood near Verdun from the German offensive early on in the battle until June 11, 1940 when the regiment began a fighting retreat to the south. By June 18, the 11th REI had lost three-fourths of its strength and the regiment withdrew to the south near Toul. The 12th REI was redeployed from its training center in Valbonne on May 11 to defend the Soissons where it arrived on May 24 and eventually began to fortify their positions. The 12 REI first experienced a form of combat for which they were unprepared when on June 5, the town of Soissons was the subject of German strafing from Stukas. By June 8, the 12th REI, in danger of being encircled, received orders to retreat to the south, however the orders did not come soon enough and parts of the 12th REI were surrounded at Soissons; the rest of the 12th REI made their way to Limoges by the signing of Second Armistice at Compiègne on June 25, 1940. By the surrender of France the 12th REI had lost 2,500 of its number. The 21st Marching Regiment of Foreign Volunteers was deployed to the Maginot Line when the German offensive began, but was shifted to the north of Verdun by the end of May. The 21st RMVE took heavy losses during an engagement with the Germans on June 8 and 9; the 21st RMVE joined the rest of the French Army in that sector in retreat when the order to retreat was given. At the time of the armistice the 21st RMVE was at Nancy where it was disarmed by German forces. The 22nd Marching Regiment of the Foreign Volunteers left its training depot at Bacarès on May 6 when it was deployed around Alsace. The German offensive forced the 22nd RMVE to be quickly redeployed on the Somme near the village of Marchélepot where it fought a defensive action from May 22 to May 26. On June 5, the 22nd RMVE was preparing to counterattack the Germans at Villers-Carbonnel alongside the 112th Infantry Division when it came under a heavy preemptive attack launched by German forces in the area. The French Forces were able to initially repulse the attack, but later succumbed to the German onslaught; the force of the Foreign Legion acquitted themselves admirably in that engagement.
 Passage 3:On 6 September that year, Pope Urban VI declared that as James of Baux's successors had forfeited their rights to the Holy See, the principality belonged to him and he devolved its government on Paul Foscari, the archbishop of Patras, who in turn made Pedro vicar general. Pedro was constantly at war with the Despotate of Morea, against whom he even used Ottoman pirates, and the Duchy of Athens under Nerio I Acciaioli. The latter was captured near Vostitsa on 10 September 1389 while trying to sit to talks with Pedro concerning Argos and Nauplia. He had to buy his freedom with concessions to the Navarrese ally, Venice. Late in 1394 or early in 1395, the Turkish general Evrenos Beg invaded the despotate and met Pedro's forces at Leontari. Together the two besieged and took Akova (28 February). After Evrenos returned to Thessaly, Pedro was defeated by the Greeks and taken captive with the grand constable Andronico Asano Zaccaria, his brother-in-law. In December, Venice paid 50,000 hyperpers for the release of her allies.

[Q]: Question: Have Liverpool or Chelsea won more titles? Passage 1:Philpott was a family doctor in Markham–Stouffville from 1998 to 2015. She served as Chief of the Department of Family Medicine at Markham Stouffville Hospital from 2008 to 2014. She is an Associate Professor in the University of Toronto’s Department of Family and Community Medicine. She was the Lead Physician of the Health For All Family Health Team in Markham, Ontario. She worked in Niger in West Africa from 1989-1998 with a faith-based non-governmental organization, where she practiced general medicine and developed a training program for village health workers. She returned to Niger in 2005 with Médecins sans Frontières during a food crisis. She was the Family Medicine lead in the Toronto Addis Ababa Academic Collaboration (TAAAC) from 2008 to 2014. In this capacity she helped colleagues at Addis Ababa University to develop the first training program for Family Medicine in Ethiopia that began in 2013. The first seven students in this programme graduated in early 2016. Philpott has been an advocate for Canada to give greater attention to the rights of refugees, particularly in respect of the health care afforded to them. In an article in the Toronto Star in 2014 she argued that "the Conservative government's cuts to refugee health care are 'cruel and unusual. Philpott is a co-curator of TEDxStouffville founded in 2012 with Dr. Eileen Nicolle. The TEDxStouffville committee, a collaboration between Health for All Family Health Team, Markham Stouffville Hospital, the University of Toronto and residents of the town of Whitchurch–Stouffville, develops its program with live speakers on the theme of Social Determinants of Health.
 Passage 2:Route 67 is mostly a two-lane surface road, with a divided four-lane section in Southbury. It begins in New Milford as a 0.5 mile concurrency with US 202 as the latter leaves a concurrency with US 7. After crossing the Housatonic River into the center of town, Route 67 breaks away to the southeast. In Bridgewater, it meets the northern end of Route 133. In Roxbury, it meets the southern end of Route 199 and the western end of Route 317. It then clips a corner of Woodbury before passing into New Haven County and the town of Southbury, where it passes the northern end of Route 172 before joining US 6 for a 4 lane divided 1.6 mile concurrency leading to a junction with I-84 at Exit 15. Here, US 6 joins I-84 West and Route 67 continues to the southeast becoming a 2-lane road once again. After intersecting Route 188, it enters Oxford, where it has a junction with the west end of Route 42. In Seymour, it passes the western end of Route 313 before crossing the Naugatuck River. On the east shore of the river, it meets the Route 8 expressway at Exits 21 & 22. It then passes the northern end of Route 115 before heading into Woodbridge, where Route 67 ends at Route 63. 
 Passage 3:Arsenal had finished the previous season as runners-up in the Premier League, overhauled by Manchester United in the final ten weeks of the season. The club did, however, retain the FA Cup, with a 1–0 win against Southampton. Such was Arsenal's effective start to the 2002–03 campaign, manager Arsène Wenger suggested his team could remain the whole season undefeated in all competitions:It's not impossible as A.C. Milan once did it but I can't see why it's so shocking to say it. Do you think Manchester United, Liverpool or Chelsea don't dream that as well? They're exactly the same. They just don't say it because they're scared to look ridiculous, but nobody is ridiculous in this job as we know anything can happen. The team lost to Everton a month after Wenger's proclamation; teenager Wayne Rooney scored the match winner, which ended a run of 30 league games without defeat. By February 2003, Arsenal moved five points clear of Manchester United at the top of the league table, but injuries to key players, not least captain Patrick Vieira, had destabilised the team. Draws in April, coupled with a defeat to Leeds United at home, mathematically ended Arsenal's chances of retaining the title. Wenger refuted opinions from the media that their season was a failure and said:
