Q: 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: What is the name of the first boat that was constructed under the Project 667BDRM Delfin? Passage 1:Walter Rowley's "Trotters" finished in 17th place in 1947–48, 14th place in 1948–49, and 16th place in 1949–50. He scored six goals in 93 league games during his spell at Burnden Park. McShane joined Manchester United in exchange for defender John Ball and £5,000 in September 1950. He was signed to replace the departing Charlie Mitten. He scored seven goals in 31 appearances in the 1950–51 season, as the "Red Devils" finished second in the league. His first goal at Old Trafford came on 7 October 1950, in a 3–1 win over Sheffield Wednesday. He was part of the United side that won the First Division title in 1951–52, scoring one goal in 12 league games that season. His goal was an important one, as it came against rivals Manchester City in a 2–1 win at Maine Road on 15 September. He then struggled with a cartilage injury, and appeared just five times in the 1952–53 campaign, as Matt Busby's side dropped to eighth place.
 Passage 2:Construction of the nuclear submarine Ekaterinburg (K-84) began at the Northern Machinebuilding Enterprise (Sevmash) in Severodvinsk on 17 February 1982, before being commissioned into the Soviet Navy on 30 December 1985. She was the second of the seven-boat Project 667BDRM Delfin class, which was developed at the Rubin Design Bureau in September 1975. A ballistic missile submarine, she was designed primarily to carry up to 16 R-29RM Shtil (NATO designation: SS-N-23 Skiff) SLBM for use against military and industrial facilities in the case of a nuclear war. Each Shtil missile carries ten 100 kt multiple independently targeted reentry vehicles, and has a circular error probable of . She is also equipped with RPK-7 Veter (NATO designation: SS-N-16 Stallion) anti-ship missiles for use against large surface vessels, and self-defense torpedoes.
 Passage 3:Cosyn's largest problems during his later tenure were mainly conflicts over administrative and fiscal problems for the Cathedral, between himself and the Chapter. On August 19, 1510, Cosyn proposed that he would visit the College of chantry priests, likely to ensure that they performed their assigned duties, such as masses for the dead. The Chapter protested stating that the prerogative to visit the college "belonged to the dean and chapter, and not to the dean alone." Cosyn backed down, and the visit was conducted by members of the chapter with the dean instead. Three years later, Cosyn and the Chapter came to a head over the appointment of the Vicar of St. Cuthbert's. The chapter favored a John Caveley, while Cosyn preferred a William Mors. The election became a lawsuit that dragged on for two years, and only ended when the Archbishop of Canterbury, William Warham arbitrated the case, and appointed Caveley as Vicar. The most significant dispute was over Cosyn's attempt to gain a Papal Dispensation that would allow him to receive the First Fruits of his position, without remaining resident for the required eight months each year. Cosyn first was granted permission by the King to petition Pope Leo X for a bull in November 1513. Cosyn had received a dispensation in 1509 to travel outside the Wells Cathedral and receive his First Fruits so long as he resided in the Roman Curia, one of his benefices or cures, or at a University to study. In 1513, Cosyn sought dispensation to receive his First Fruits, while being able to travel on the King's business. The Pope granted Cosyn's request in October, 1513. The debate between Cosyn and the Chapter continued on, and the end result seems to be that Cosyn won the liberty to perform the King's business, though he had to maintain residency at Wells for six months of the year.
