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: In what countries are the headquarters of the churches that venerate Mari as a saint? Passage 1:White sharks also attack dolphins and porpoises from above, behind or below to avoid being detected by their echolocation. Targeted species include dusky dolphins (Lagenorhynchus obscurus), Risso's dolphins (Grampus griseus), bottlenose dolphins (Tursiops ssp.), Humpback dolphins (Sousa ssp.), harbour porpoises (Phocoena phocoena), and Dall's porpoises (Phocoenoides dalli). Groups of dolphins have occasionally been observed defending themselves from sharks with mobbing behaviour. White shark predation on other species of small cetacean has also been observed. In August 1989, a juvenile male pygmy sperm whale (Kogia breviceps) was found stranded in central California with a bite mark on its caudal peduncle from a great white shark. In addition, white sharks attack and prey upon beaked whales. Cases where an adult Stejneger's beaked whale (Mesoplodon stejnegeri), with a mean mass of around , and a juvenile Cuvier's beaked whale (Ziphius cavirostris), an individual estimated at , were hunted and killed by great white sharks have also been observed. When hunting sea turtles, they appear to simply bite through the carapace around a flipper, immobilizing the turtle. The heaviest species of bony fish, the oceanic sunfish (Mola mola), has been found in great white shark stomachs.
Passage 2:Saint Mari, also known as Mares and originally named Palut, is a saint of the Church of the East. He was converted by Thaddeus of Edessa (a.k.a. Addai) and is said to have had Mar Aggai as his spiritual director. He is believed to have done missionary work around Nineveh, Nisibis, and along the Euphrates, and is said to have been one of the great apostles to Syria and Persia. He was buried in Dair-Kuni. His feast day is 5 August in the Christian calendar. He and Thaddeus are credited with the Liturgy of Addai and Mari. Despite the fact that there is little, if any, concrete information on Mari, he is still venerated as a saint by the Assyrian Church of the East, the Chaldean Catholic Church, the Roman Catholic Church, and the Syro-Malabar Catholic Church. He is distinct from St Mari of the seventy disciples with whom the Apocryphal Acts of Mar Mari are connected.
Passage 3:UConn started the season strong, winning their first five games. The Huskies easily won their first game 353 against Division I-Football Championship Subdivision (Division I-FCS) opponent Hofstra. The second game, at Temple, was played as the remnants of Hurricane Hanna hit Philadelphia. UConn won 129 in overtime as Donald Brown ran for a then-career high 214yards and scored the game-winning touchdown. Connecticut next avenged their loss to Virginia from 2007, winning the rematch 4510. Baylor was next on the schedule; the Huskies pulled out the win in a back-and-forth game, 3128. Connecticut opened Big East conference play in their next game against Louisville. The game was not decided until UConn linebacker Lawrence Wilson returned an interception for a touchdown with 2:45 left in the fourth quarter, giving the Huskies a 2621 lead they would not relinquish. This was the second straight season where Connecticut won their first five games; before 2007, they had not opened a season so successfully since 1995, when they won their first six straight. Following the game, UConn achieved their first and only ranking of the year, appearing at No.24 in the Associated Press (AP) and Harris polls and No.23 in the Coaches' poll. However, starting quarterback Tyler Lorenzen broke his foot in the Louisville game; the Huskies would be forced to rely on backup Zach Frazer for the next few games.
