You will be given a definition of a task first, then some input of the task.
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 parties were involved in the war that Maitland volunteered for with the Imperial Yeomanry? Passage 1:Mieszko I, Duke of Cieszyn, the first ruler of the duchy, died in 1315 and afterwards his sons divided its land into two parts alongside Biaa River: diminished Duchy of Teschen to west and Duchy of Oswiecim to east. In the middle of the 15th century Duchy of Oswiecim was bought into the Crown of the Kingdom of Poland and so the river constituted henceforth the border between Polish and the Bohemian Crown (since 1526 part of the Habsburg Monarchy). Upon the First Partition of Poland in 1772 the river ceased to be a state border and continued as a regional border between Austrian Silesia to the west and Galicia to the east. After World War I and the 1919 PolishCzechoslovak War it separated the Polish part of Cieszyn Silesia in the Autonomous Silesian Voivodeship from Lesser Polish Krakow Voivodeship.
Passage 2:The elder son of the 13th Earl of Lauderdale, by his first wife, Charlotte Sleigh, a daughter of Lieutenant-Colonel Sleigh of the 77th Foot, Maitland was commissioned into the Royal Scots Fusiliers in 1886, transferred to the 2nd Dragoons in 1887 and to the Scots Guards in 1894, from which he retired as a lieutenant. After the outbreak of the Second Boer War in late 1899, he volunteered for active service with the Imperial Yeomanry in South Africa and was appointed adjutant of the 20th battalion on 21 March 1900. He served in South Africa 19001901, when he was mentioned in despatches. After his return, he was Assistant Director of Auxiliary Forces on the Headquarters Staff from 1904 to 1908. He saw further active service in the European War of 19141918, in which he was wounded. He was appointed OBE in 1919 and succeeded his father in 1924, taking up residence at Thirlestane Castle near Lauder in Scotland.
Passage 3:Gradually, the size of the issues was decreased as the publisher was reluctant to raise the cover price from the original 10 cents, so there were fewer stories. For a while, Congo Bill and Tommy Tomorrow were the two features in addition to Superman. Writer Robert Bernstein and artist Howard Sherman revamped the "Congo Bill" backup feature in issue #248 (January 1959) in a story wherein the character gained the ability to swap bodies with a gorilla and his strip was renamed Congorilla. The introduction of Supergirl by Otto Binder and Al Plastino occurred in issue #252 (May 1959). Following this debut appearance, Supergirl adopted the secret identity of an orphan "Linda Lee" and made Midvale Orphanage her base of operations. In Action Comics #261 (February 1960), her pet cat Streaky was introduced by Jerry Siegel and Jim Mooney. Supergirl joined the Legion of Super-Heroes in issue #276 and acted for three years as Superman's "secret weapon," until her existence was revealed in Action Comics #285 (January 1962). In the view of comics historian Les Daniels, artist Curt Swan became the definitive artist of Superman in the early 1960s with a "new look" to the character that replaced Wayne Boring's version. Bizarro World first appeared in the story "The World of Bizarros!" in issue #262 (April 1960). Writer Jim Shooter created the villain the Parasite in Action Comics #340 (Aug. 1966).
