Q: Question: What side was the Austro-Hungarian army on? Passage 1:In the 1980s, with the support of Swami Omanand Saraswati, he catalogued and evaluated metallic artefacts of the so-called Copper Hoard Culture by means of European methods and models for the first time, whereby numerous finds came to light especially in the Kanya Gurukul in Narela/Haryana. These artefacts appear to be non-functional objects, probably used in rituals or simply deposited in hoards, to judge from a lack of use-wear. Far away in Odisha, Yule published a find from a metals period cemetery in Sankarjang which may be the earliest musical instrument in India. He documented the early historic fortress at Sisupalgarh by means of a laser scanner, ground penetrating radar and a hand-held GPS receiver. Together with Corinna Borchert, Yule uncovered illegal building development within this nationally protected Mauryan site. From 2001-2004 in India, Yule documented so-called mud forts and other archaeological sites for the first time, especially in Odisha along the Mahanadi and Chhattisgarh. Images of his work especially in Odisha appear in the image bank heidICON.
 Passage 2:In 2003, Minnesota-raised singer, writer, and guitarist Craig Finn and New York City bartender and bassist Galen Polivka began talking about starting a band. Finn and lead guitarist Tad Kubler (both formerly of Lifter Puller) developed the idea of The Hold Steady when, while watching The Band concert film The Last Waltz, Finn asked Kubler, "Dude, why aren't there any bands like this anymore?" The Hold Steady's 2004 debut album Almost Killed Me, released on Frenchkiss Records, was a sleeper hit among music critics, reaching No. 31 in the Pazz & Jop critics poll that year, an achievement which Finn described as "like being nominated for an Oscar or something." In May 2005, they were the first rock band to grace the front page of The Village Voice in 15 years . They were Blender's 2006 "Band of the Year".
 Passage 3:Antoni Chruściel was born on 16 July 1895 in the village of Gniewczyna Łańcucka halfway between Łańcut and Przeworsk, to Andrzej Chruściel, a local farmer and the vogt of that village. In 1909, while still a student at a local gymnasium in Jarosław, Chruściel joined the secret scouting troop; he was also active in the Zarzewie movement. In 1914, after the outbreak of the First World War he moved to Lwów, where he joined the Eastern Legion. Soon afterwards, as a citizen of Austria-Hungary, he was drafted into the Austro-Hungarian Army. After graduating from an NCO school in May 1915 he served at various posts, including his service as a commanding officer of a company of the 90th Infantry Regiment. After the dissolution of Austria-Hungary and the chaos at the eastern front, Chruściel's regiment was the only unit in the entire Austro-Hungarian Army to return to the barracks as an organized entity and with arms. Few weeks later Chruściel, together with most of his unit, joined the newly formed Polish Army.
