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: When was Joseph's brother born? Passage 1:After attending Berkshire Country Day, Aronoff went to music school for one year at the University of Massachusetts Amherst and spent four more years at the Indiana University School of Music (presently known as Jacobs School of Music) as a performance major in classical music as well as spending a summer at the Aspen School of Music run by Juilliard School of Music. He also spent one summer at Tanglewood in the Fellowship program (now Tanglewood Music Center), which at that time was managed by the Boston Symphony Orchestra where he worked with conductors Leonard Bernstein, Aaron Copland and Arthur Fiedler. While studying at Indiana University from 1972 to 1976 Aronoff studied under timpanist George Gaber. He also studied privately with Vic Firth and Arthur Press, both formerly with The Boston Symphony Orchestra. After graduating in 1976 he was offered jobs with the Jerusalem Symphony Orchestra and Quito Ecuador Symphony Orchestra but decided to move to the East Coast to study in Boston with Alan Dawson, a teacher from Berklee College of Music, and with Gary Chester in New York where he began to concentrate on jazz and fusion music.
 Passage 2:He began 2018 in Europe with third at the Czech Indoor Gala and a runner-up finish at the Cinque Mulini. A 5000 m win at the Ethiopian U20 Championships and a personal best of 13:04.63 minutes to win at the Meeting Iberoamericano de Atletismo saw him enter the 2018 IAAF World U20 Championships saw him enter the competition as the second fastest runner after training mate Selemon Barega. He was beaten by the heat, however, and finished fifth in the 5000 m. He made his IAAF Diamond League debut that year, placing seventh at Athletissima. He closed the year with third place at the Great Ethiopian Run. At the start of 2019 he continued to show his strength over distance with second place at the Giro Media Blenio 10K. Turning to the track, he won the Ethiopian national title, was fifth at the Shanghai Golden Grand Prix, then had his first Diamond League victory by winning the 5000 m at the Golden Gala, beating his partner Selemon Barega. He was third at that year's Athletissima and placed fourth at the Diamond League final at the Weltklasse Zürich.
 Passage 3:In the biblical account, Joseph's other son is Manasseh, and Joseph himself is one of the two children of Rachel and Jacob, the other being Benjamin. Biblical scholars regard it as obvious, from their geographic overlap and their treatment in older passages, that originally Ephraim and Manasseh were considered one tribe – that of Joseph. The Book of Revelation, however, accords only Ephraim the tribal name of Joseph. According to several biblical scholars, Benjamin was originally part of the suggested Ephraim-Manasseh single "Joseph" tribe, but the biblical account of Joseph as his father became lost. A number of biblical scholars suspect that the distinction of the Joseph tribes (including Benjamin) is that they were the only Israelites which went to Egypt and returned, while the main Israelite tribes simply emerged as a subculture from the Canaanites and had remained in Canaan throughout. According to this view, the story of Jacob's visit to Laban to obtain a wife originated as a metaphor for this migration, with the property and family which were gained from Laban representing the gains of the Joseph tribes by the time they returned from Egypt; according to textual scholars, the Jahwist version of the Laban narrative only mentions the Joseph tribes, and Rachel, and does not mention the other tribal matriarchs at all.
