In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

[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.

[Q]: Question: Is the person Phang was a key influence to moving into record production still alive today? Passage 1:Corona's first single, "The Rhythm of the Night", was released in Italy in November 1993 on Roberto Zanetti's DWA record label, and became an instant hit. It featured the voice of Italian singer Giovanna Bersola, better known by her stage name Jenny B. It stayed at number 1 on the Italian music chart for eight consecutive weeks. However, the song was not released elsewhere until the following year. A remixed version of the song became a number 2 hit in the United Kingdom in September 1994. Like several early 1990s Eurodance/Hi-NRG songs that eventually became American hits, such as "Get Ready For This", "Twilight Zone" and "Tribal Dance" by 2 Unlimited and "Strike It Up", "I Don't Know Anybody Else" and "Everybody Everybody" by Black Box, "The Rhythm of The Night" did not become popular in the United States until well after its success had peaked in Europe. However, by spring 1995, the song was all over American radio and clubs, eventually reaching #11 on the Billboard Hot 100. The song was later released as a track in the 1995 debut studio album "The Rhythm of the Night". Lead vocals for the remaining songs in the album were provided by Welsh singer Sandy Chambers who would also provide vocals on the group's second album Walking On Music.
Passage 2:Phang started his reggae label Powerhouse in the early 1980s. His first hits were Little John's "True Confessions" and "Roots Girl", both released in 1983. He followed suit with Sugar Minott's "Buy off the Bar" and Barrington Levy's "Money Move" which were both two major hits that year. In the summer of 1984 he released Michael Palmer's "Lick Shot" which became of the biggest tunes that summer. Many of the most successful dancehall stars of the 1980s recorded for Phang. Half Pint's all-time greatest hit "Greetings" was released on Powerhouse in 1986. Conroy Smith's first song "Indian Lady" was also released on Phang's label. Other artists include Josey Wales, Freddie McGregor, Nitty Gritty, Tenor Saw, Little John, Brigadier Jerry, Barrington Levy, Admiral Bailey, Al Campbell, Charlie Chaplin, Cutty Ranks, Dominic, Echo Minott, Frankie Paul, Gregory Isaacs, John Wayne, Yellowman, Supercat, and General Echo. Phang mostly used riddims produced by Sly & Robbie, this gave him an advantage compared to other producers. His sound is characterized by the abundant use of reverb on the snare drums. However, by the late 1980s he stopped producing music. Phang was a key influence on Philip "Fatis" Burrell's move into record production.

He was the interim head coach at the University of Minnesota, having replaced Tim Brewster, who was fired midway through the Golden Gophers' 2010 season.

[Q]: Question: Of the countries Ottwalt passed through, which one existed as a country for the longest? Passage 1:In 1933, Ottwalt and his wife, Waltraut, left Germany and went into exile in Denmark, then, by way of Czechoslovakia, ended up in the Soviet Union. Living in Moscow, Ottwalt wrote for the German exile magazine Internationale Literatur (published by Johannes R. Becher) and was an editor at Vegaar Bibliothek. He also wrote for the Deutsche Zentral Zeitung. In 1936, he and his wife were ensnared in the Stalinist purges and arrested by the Soviet secret police, the NKVD. He was charged with suspicion of espionage, sentenced to forced labor and deported to a gulag near Archangelsk. His wife was sentenced to forced labor in Kotlas. She was deported back to Germany in January 1941 and didn't learn about his death until January 1958, when the Soviet Red Cross informed her that her husband had died on 24 August 1943.
Passage 2:The earliest surviving written criticisms of Islam are to be found in the writings of Christians who came under the early dominion of the Islamic Caliphate. One such Christian was John of Damascus (c. 676749 AD), who was familiar with Islam and Arabic. The second chapter of his book, The Fount of Wisdom, titled "Concerning Heresies", presents a series of discussions between Christians and Muslims. John claimed an Arian monk (whom he did not know was Bahira) influenced Muhammad and viewed the Islamic doctrines as nothing more than a hodgepodge culled from the Bible. Writing on Islam's claim of Abrahamic ancestry, John explained that the Arabs were called "Saracens" (Greek , Sarakenoi) because they were "empty" (, kenos, in Greek) "of Sarah". They were called "Hagarenes" because they were "the descendants of the slave-girl Hagar".
Passage 3:Freeh was born January 6, 1950, in Jersey City, New Jersey, the son of Italian-American parents Bernice (nee Chinchiolo), a former bookkeeper, and William Freeh, Sr., a real estate broker. Freeh, a native of North Bergen, graduated from St. Joseph's High School in West New York, NJ in 1967, where he was taught by Christian Brothers. He then graduated Phi Beta Kappa from Rutgers UniversityNew Brunswick with a Bachelor of Arts degree in 1971, and received a Juris Doctor degree from Rutgers School of LawNewark in 1974 and a Master of Laws degree in criminal law from New York University School of Law in 1984. Freeh was an FBI Special Agent from 1975 to 1981 in the New York City field office and at FBI Headquarters in Washington, D.C. In 1981, he joined the U.S. Attorney's Office for the Southern District of New York as an Assistant United States Attorney. Subsequently, he held positions there as Chief of the Organized Crime Unit, Deputy United States Attorney, and Associate United States Attorney. He was also a first lieutenant in the United States Army Reserve.
