Detailed Instructions: 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.
Q: Question: What other famous people came out of where The Beatles were based? Passage 1:Anne Beloff was born in 1921 in Hampstead to Simon Beloff and Marie Katzin. Her parents were of Russian–Jewish background, and her siblings included the historian Max Beloff, Baron Beloff, the psychologist John Beloff, the journalist Nora Beloff, and the politician Renee Soskin. She earned a degree in chemistry from University College London in 1942 before completing a PhD in the biochemistry of skin burns with Rudolph Peters at the University of Oxford. She visited Harvard Medical School in 1946 to perform research and returned to the UK in 1948. In the same year she married Ernst Boris Chain, a biochemist who had won the Nobel Prize in Physiology or Medicine in 1945, and moved with him to Rome.
 Passage 2:Bieberbach wrote a habilitation thesis in 1911 about groups of Euclidean motions – identifying conditions under which the group must have a translational subgroup whose vectors span the Euclidean space – that helped solve Hilbert's 18th problem. He worked on complex analysis and its applications to other areas in mathematics. He is known for his work on dynamics in several complex variables, where he obtained results similar to Fatou's. In 1916 he formulated the Bieberbach conjecture, stating a necessary condition for a holomorphic function to map the open unit disc injectively into the complex plane in terms of the function's Taylor series. In 1984 Louis de Branges proved the conjecture (for this reason, the Bieberbach conjecture is sometimes called de Branges' theorem). There is also a on space groups. In 1928 Bieberbach wrote a book with Issai Schur titled Über die Minkowskische Reduktiontheorie der positiven quadratischen Formen.
 Passage 3:The recordings made by the Beatles, a rock group from Liverpool, England, from their inception as the Quarrymen in 1957 to their break-up in 1970 and the reunion of their surviving members in the mid-1990s, have huge cultural and historical value. The studio session tapes are kept at Abbey Road Studios, formerly known as "EMI Recording Studios," where the Beatles recorded most of their music. While most have never been officially released, their outtakes and demos are seen by fans as collectables, and some of the recordings have appeared on countless bootlegs. Until 2013, the only outtakes and demos to be officially released were on The Beatles Anthology series and its tie-in singles, and bits of some previously unreleased studio recordings were used in  video game as ambient noise and to give songs studio-sounding beginnings and endings. In 2013, Apple Records released the album The Beatles Bootleg Recordings 1963, which includes previously unreleased outtakes and demos from 1963, to stop the recordings from falling into the public domain.
