You will be given a definition of a task first, then some input of the task.
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.

Question: When was the organization that Tanaka made his debut in 1999 founded? Passage 1: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.
 Passage 2: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 3:Tanaka made his New Japan Pro Wrestling debut on April 10, 1999 and would proceed to take part in Best of the Super Juniors in block B. Tanaka would reappear for New Japan in late 1999 to early 2000 before he joined the New Japan roster as a full-time competitor. His natural talent enabled him to immediately rise in the junior heavyweight ranks and win the IWGP Junior Heavyweight Tag Team Championship in July with Koji Kanemoto, who used a similar but more ground-oriented style. The Kanemoto-Tanaka combination was reminiscent of the old Akira Maeda-Nobuhiko Takada combination in 1987. In October, Tanaka won the IWGP Junior Heavyweight Championship - thus becoming the first man to hold both junior titles at the same time. In March 2001, Tanaka and Kanemoto lost their titles to El Samurai and Jushin Thunder Liger, in June he lost in the finals of 2001's Best of the Super Juniors to Liger and in July he lost his singles title. Even with all these losses, Tanaka finished 2001 strong, winning the G1 Jr. Six Man Tag Team Tournament Masahito Kakihara and Masayuki Naruse. For a second time in his career, Tanaka held both junior titles, defeating Masahito Kakihara for the IWGP Junior Heavyweight Champion and defeating Gedo and Jado with Jushin Thunder Liger for the IWGP Junior Heavyweight Tag Team Championship. After Koji Kanemoto defeated Tanaka in 2002's Best of the Super Juniors, Kanemoto defeated Tanaka once again for his IWGP Junior Heavyweight Championship, and a month later lost his tag team championship to Tsuyoshi Kikuchi and Yoshinobu Kanemaru.
