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: Which modernist sculptor is younger, Joseph Csaky or Jean Arp? Passage 1:By 1970, the five Parliaments singers were touring with five backing musicians known separately as Funkadelic. The highly rehearsed performances and suited look of The Parliaments gave way to the members dressing in their own outrageous styles. Haskins wore long johns on stage. Due to the contractual issues surrounding the group name, Clinton signed the band as Funkadelic to Westbound Records. The ensemble released their first album Funkadelic in 1970. Clinton also renamed his group of singers Parliament (but still with the Funkadelic musicians as official members) and signed that act to the Holland-Dozier-Holland-owned record label, Invictus. Parliament released their first album Osmium in 1970. Clinton now had two groups that were actually one entity. Under the name Funkadelic, the ensemble was geared towards a rock audience, and as Parliament it was aimed at a soul music audience. Collectively, they became known as Parliament-Funkadelic, or P-Funk. Haskins contributed to P-Funk as a writer through 1972. He toured and appeared on P-Funk albums as a singer, and occasionally as a guitarist, throughout the 1970s. In June 1977 at the height of P-Funk's popularity, Haskins (along with other original Parliaments Calvin Simon and Grady Thomas) left the ensemble over financial and management disputes with Clinton.
 Passage 2:The Channel is of geologically recent origin, having been dry land for most of the Pleistocene period. Before the Devensian glaciation (the most recent glacial period, which ended around 10,000 years ago), Britain and Ireland were part of continental Europe, linked by an unbroken Weald–Artois anticline, a ridge that acted as a natural dam holding back a large freshwater pro-glacial lake in the Doggerland region, now submerged under the North Sea. During this period the North Sea and almost all of the British Isles were covered by ice. The lake was fed by meltwater from the Baltic and from the Caledonian and Scandinavian ice sheets that joined to the north, blocking its exit. The sea level was about lower than it is today. Then, between 450,000 and 180,000 years ago, at least two catastrophic glacial lake outburst floods breached the Weald–Artois anticline.
 Passage 3:In 1953, the foundation's collecting criteria expanded under its new director, James Johnson Sweeney. Sweeney rejected Rebay's dismissal of "objective" painting and sculpture, and he soon acquired Constantin Brâncuși's Adam and Eve (1921), followed by works of other modernist sculptors, including Joseph Csaky, Jean Arp, Calder, Alberto Giacometti and David Smith. Sweeney reached beyond the 20th century to acquire Paul Cézanne's Man with Crossed Arms (c. 1899). The same year, the foundation also received a gift of 28 important works from the Estate of Katherine S. Dreier, a founder of America's first collection to be called a modern art museum, the Société Anonyme. Dreier had been a colleague of Rebay's. The works included Little French Girl (1914–18) by Brâncuși, an untitled still life (1916) by Juan Gris, a bronze sculpture (1919) by Alexander Archipenko and three collages (1919–21) by German Hanoverian Dadaist Schwitters. It also included works by Calder, Marcel Duchamp, El Lissitzky and Mondrian. Among others, Sweeney also acquired the works of Alberto Giacometti, David Hayes, Willem de Kooning and Jackson Pollock.
