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: What book first introduces the white wizard? Passage 1:Meanwhile, the wizard Gandalf the White and the hobbit Pippin arrive at Minas Tirith to warn Denethor, the Steward of the Throne, about the upcoming war—only to discover that the Steward has become insane and means to take his own life. Frodo and Samwise continue toward Mount Doom (eluding Ringwraiths and infiltrating a "battalion of orcs" in the process) only to be attacked by Gollum. As Sam holds Gollum off, Frodo reaches the Crack of Doom; but is subverted by the Ring. At the same time, Gondor's neighboring country, Rohan, helps it claim victory in the Battle of Pelennor Fields, where King Théoden and the Witch-King of Angmar are slain. Upon his own arrival, Aragorn plans to confront Sauron at the gates of Mordor. Here, he quarrels with the Mouth of Sauron and the two armies prepare for battle.
 Passage 2:It was used initially by transient work crews timbering and building temporary river boats to haul cargo known as arks, a common solution to ship upstream resources out of the frontier. As such early on it anchored a sawmill, tavern, crude housing, tool and work sheds, and in 1804–05, a toll house built for the Lehigh and Susquehanna turnpike, climbing the nearby ravine of Jean's Run as it began the sharp ascent up Broad Mountain to pass in succession along the banks of the Black Creek, Quakake Creek, Beaver Creek valleys in (the future) Carbon County, Pennsylvania then climb Hazel Creek into Luzerne County up to the flat area of the Mountain pass, a marshy saddle which would become Hazelton, PA near the 1780s settlement of St John's along the descent to Nescopeck on the Susquehanna – PA 93 follows much of the same road bed, save for starting at an elevated altitude from the nearby town of Nesquehoning, PA via a high level bridge.
 Passage 3:Amongst her first commissions was the St Ita window for St Brendan's cathedral in Loughrea in 1904, which was designed by Sarah Purser. O'Brien joined An Túr Gloine in 1906, beginning her career there by designing Angel of the Annunciation window in the Enniskillen convent chapel. For a window in the Wilson private chapel Coolcarrigan, Naas, County Kildare in 1912, O'Brien incorporated Celtic design, some drawing on the Book of Durrow. In 1914, she toured the cathedrals of Paris, Rouen, and Chartres with Purser and Wilhelmina Geddes. O'Brien designed three windows depicting St John, St Flannan, and St Munchin, for the Honan Chapel in University College Cork in 1916. Her 1923 design of the centenary memorial window in St Andrew's church, Lucan, represented the parable of the Good Shepherd. When in 1925 An Túr Gloine became a cooperative society, O'Brien became a shareholder along with Ethel Rhind, Evie Hone, and Michael Healy.
