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 did the sovereign entity that built the Victor Emmanuel Railway begin? Passage 1:"Learn the Hard Way" is the album's fourth track. It is the third song on the album, and shares similarities with the song "Never Say Never". The Guy Roche-produced "Almost Doesn't Count" is the fifth track. Brandy performed the song in the 1999 film Double Platinum, starring Diana Ross and herself. The international single "Top of the World" is the album's sixth track. It is a collaboration with Mase and the song talks about Brandy as a popstar just trying to be her and not feeling like being in her own world. In the music video, directed by Paul Hunter, Brandy was featured incurring various supernatural phenomena. She spontaneously floated in the air, flipping and somersaulting above random objects; telephone poles and vehicles, as people stopped to stare. These strange phenomena also included balancing herself vertically and horizontally alongside skyscrapers and buildings. The Darkchild-produced "U Don't Know Me (Like U Used To)", which is the album's seventh and final single, is noted for its remix version with Shaunta and Da Brat. The remix was released as the lead single to the same-named EP. "Never Say Never", also produced by Rodney Jerkins, is the eighth song of the album. "Never Say Never" was released as a Germany single in 2000. "Truthfully", a ballad about a broken relationship, was penned by former Boyz II Men member, singer-songwriter Marc Nelson. Recorded in a single take, it took Nelson five different sessions to get Norwood in the recording studio as she felt initially nervous about working with him. Main production on the song was helmed by Harvey Mason, Jr. who received his first major placement as a producer on "Truthfully". Mason was consulted by Jerkins after he had shopped around several tracks for record executives.
 Passage 2:In 1926, the opera was first presented at the Salzburg Festival, staged by Lothar Wallerstein in Viennese settings, twice conducted by Clemens Krauss and once by Richard Strauss himself. Lotte Lehmann was Salzburg's first Ariadne. Wallerstein was also the stage director of the second Viennese production in 1935, with settings by Oskar Strnad and costumes by Ladislaus Czettel. Josef Krips conducted. There were 38 performances until September 1943. Three months later a new production by Heinz Arnold was presented, with settings by Wilhelm Reinking and conducted by Karl Böhm. The cast featured Maria Reining as Ariadne, Max Lorenz as Bacchus, Alda Noni as Zerbinetta, Irmgard Seefried as composer, Paul Schöffler as Musiklehrer, Erich Kunz as Harlekin and Emmy Loose as Najade. Due to the war this production could only be shown seven times.
 Passage 3:The Victor Emmanuel Railway, which included both the Culoz–Modane railway across Savoy and the Turin–Modane railway across Piedmont, was largely built in the 1850s by the Kingdom of Sardinia and named after its king, Victor Emmanuel II. Until 1860 Sardinia included both Savoy and Piedmont. The line from Turin to Susa was inaugurated on 22 May 1854. Work on the tunnel began on 31 August 1857 and was completed in September 1871. Work had begun on the line between Bussoleno and Bardonecchia in 1867 and was completed at the same time as the tunnel. The tunnel and line were opened on 16 October 1871. By that time, the Savoy side of the tunnel had become part of France. The decision of the engineers to begin the line at Bussoleno in order to reduce the gradient on the climb near Meana was much criticized for bypassing the city of Susa, which was left isolated on a short branch line. The opening of the tunnel also led to the closure of the short-lived Mont Cenis Pass Railway. In 1865 the line became part of the network of the Società per le strade ferrate dell'Alta Italia (Upper Italian Railways, SFAI) on its foundation in 1865 and was taken over by the Rete Mediterranea (Mediterranean Network) in 1885. Finally in 1905 it became part of the Ferrovie dello Stato network.
