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: How old was the man that speculated that John 21 was appended to the gospel at a later date? Passage 1:The New Testament has been preserved in three major manuscript traditions: the 4th century CE Alexandrian text-type; the Western text-type, also very early but prone to paraphrase and other corruptions; and the Byzantine text-type, which makes up above 80% of all manuscripts, the majority comparatively very late in the tradition. Scholars regard the Alexandrian text-type as generally more authoritative when treating textual variations. The majority of differences are minor—matters such as variant spellings—although at a few points the oldest manuscripts show important inconsistencies compared with the more recent ones: these include the endings of Mark 16, describing Jesus' post-resurrection appearances, from the Gospel of Mark; the absence from John of the story of the woman taken in adultery; and an explicit reference to the Trinity in 1 John (the Comma Johanneum). Scholars such as Bart Ehrman have speculated that John 21 was appended to the gospel at a later date, but no manuscript evidence for this assertion has been discovered.
 Passage 2:Wasson was born Isabel Deming Bassett in Brooklyn, NY on January 11, 1897, daughter of urban planner Edward Bassett and Annie Preston Bassett, and sister of inventor and engineer Preston Bassett. Wasson graduated Phi Beta Kappa from Wellesley College in 1918, majoring in history so she could take a wide range of science courses. She took classes in geology after graduation at the University of Chicago and the Massachusetts Institute of Technology. She met her future husband, petroleum geologist Theron Wasson, whom she married in 1920, while working towards a master's degree in geology at Columbia University, which she finished in 1934. They had three children: Elizabeth W. Bergstrom, a biologist; Edward B. Wasson, a petroleum geologist; and Anne Harney Gallagher, an art historian. Wasson worked as a petroleum geologist in her husband's office at the Pure Oil Company from the early 1920s until 1928. She published two scholarly articles on geology, one co-authored with her husband about an oil field discovered by Pure Oil in 1914, and another by herself about the ages of rock formations in Ohio and new terminology for them; the latter was cited in a number of other papers and a recent book. After 1928 she spent over 50 years in River Forest, IL, teaching science in the local public schools, lecturing, bird watching (ornithology), and mentoring generations of young naturalists. She was quoted in this 1986 Chicago Tribune article as an expert on local geology at age 89. She was honored for her contributions to local history in 1982 when the Wasson Room was named after her in a local school to hold local history resources. Her interests included archaeology; she discovered a Native American religious mound in Thatcher Woods, near her house in River Forest, in the 1930s. An article about her discovery called her "the one who started the environmental education movement in America back in the 1920s and '30s." Theron and Isabel divorced in 1953 and she did not remarry. From 1953-1954, Wasson served as President of the Chicago Ornithological Society. Wasson also taught classes at the Morton Arboretum in Lisle, Illinois. She died in La Grange Park, IL, in 1994.
 Passage 3:1999: Britney Spears was the big winner of the night winning four awards, including Best New Act and Best Song for "...Baby One More Time". She also performed during the ceremony, entertaining the crowd with a medley of her songs "...Baby One More Time" and "(You Drive Me) Crazy". The Free Your Mind Award, which honours an individual or organisation for aiding in humanitarian efforts and fighting prejudice, was given to Bono for his world peace work. Puff Daddy performed "My Best Friend" backed by a full gospel choir, followed by Iggy Pop, who stagedived into the crowd during the track "Lust for Life". Whitney Houston sang a medley of "Get It Back" and "My Love Is Your Love", while Mariah Carey performed "Heartbreaker". Marilyn Manson, who wore nothing but a G-string, closed the show with a performance of "Rock Is Dead".
