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.
Q: Question: How long did Rudolph have rule? Passage 1:As early as 500 BC, the Treveri, a people of mixed Celtic and Germanic stock, from whom the Latin name for the city of Trier, Augusta Treverorum, is also derived, settled in Veldenz's fertile valley. After them, from about 50 BC to AD 500 came the Romans. Possibly about the year 1129, Gerlach I built a castle, today's Schloss Veldenz. In 1286, Rudolph of Habsburg granted Veldenz town and market rights. By 1444, the castle and its environs had passed to the Counts of Palatinate-Zweibrucken, or between 1543 and 1694 the Principality of Palatinate-Veldenz. In 1752, in Burgen near Veldenz, the widely known robber, Johann Peter Petri, also known as Schwarzer Peter ("Black Peter"), was born. From 1777 to 1797, Veldenz belonged to Bavaria. After French rule as part of Sarre department, it was annexed to Prussia in 1815. In 1835 the Veldenz Lion was adopted as the Bavarian Lion in that kingdom's coat of arms. Even today, many examples of comital building undertakings from the 18th century can be found, among them the town hall.
Passage 2:While most of Alexander's career was spent in lyric roles from the Italian and French repertory, Alexander had enough heft in his voice to successfully tackle some of the lighter Heldentenor roles of Richard Wagner and Richard Strauss. Aside from a handful of these roles, however, his repertoire at the Metropolitan did not include heavier parts. Rather, he was known there for an expansive lyric repertoire that encompassed the works of Mozart, Puccini, Verdi, and Donizetti among others. His signature roles included Alfredo in La traviata, Arbace in Idomeneo, Belmonte in Die Entfuhrung aus dem Serail, the Duke of Mantua in Rigoletto, Edgardo from Lucia di Lammermoor, Ferrando in Cosi fan tutte, Hoffman in Les contes d'Hoffmann, Lieutenant B. F. Pinkerton in Madama Butterfly, Rodolfo in La boheme, and the title roles in Don Carlos and Faust.
Passage 3:Kathleen Ryan was one of the eight children of Seamus Ryan, a member of Seanad Eireann and his wife Agnes Ryan nee Harding who came from Kilfeacle and Solohead respectively in County Tipperary and who were Republican activists during the Irish War of Independence. They opened a shop in Parnell Street, Dublin in the 1920s which was the first of 36 outlets which were known as "The Monument Creameries". The family lived at Burton Hall, near Leopardstown Racecourse in the Dublin suburb of Foxrock. Her brother was John Ryan, an artist and man of letters in bohemian Dublin of the 1940s and 50's, who was a friend and benefactor of a number of struggling writers in the post-war era, such as Patrick Kavanagh. He started and edited a short-lived literary magazine entitled Envoy. Among her other siblings were Fr. Vincent (Seamus) (19302005), a Benedictine priest at Glenstal Abbey, Sister Ide of the Convent of The Sacred Heart, Mount Anville, Dublin, Oonagh (who married the Irish artist Patrick Swift), Cora who married the politician, Sean Dunne, T.D. When Kathleen was an undergraduate at University College Dublin, she was introduced to the future Dr. Dermod Devane of Limerick. They were married in the society wedding of 1944 and the couple had three children, but the marriage was annulled in 1958.
