Q: Question: How many people lived in Idaho Territory the year Clark first arrived there? Passage 1:Born on August 21, 1883, in Hadley, Indiana, Clark arrived in eastern Idaho Territory in 1884. His father Joseph engineered an early canal on the Snake River and later became the first Mayor of Idaho Falls, Idaho in 1900. Clark attended the public schools and left Idaho Falls High School at age 15 and then attended school in Terre Haute, Indiana. Clark returned to Idaho Falls working as a mercantile clerk, then moved to Mackay, Idaho shortly after its founding and saved money to attend the University of Michigan Law School, but did not graduate but instead read law to enter the bar in 1904. He entered private practice in Mackay from 1904 to 1930. He was a Judge Advocate General for the State of Idaho from 1914 to 1915. Clark left to fight in 1916 in the Border War and then World War I. He served in a machine gun unit and achieved the rank of lieutenant in the United States Army. He was a member of the Idaho House of Representatives from 1913 to 1916. He returned to private practice in Idaho Falls from 1930 to 1940. He served in the Idaho Senate from 1933 to 1936. He was the Mayor of Idaho Falls from 1937 to 1938. He was the Governor of Idaho from 1941 to 1942.
 Passage 2:Initially a supporter of the Swiss fascist movement of Arthur Fonjallaz, he came to wider attention in 1949 when he published Ubu Justicier au Premier Procès de Nuremberg, one of the first works to question the veracity of the Holocaust. Increasingly active in neo-fascism, he organized conferences in Malmö in 1951 which led to the formation of a pan-European nationalist group known as the European Social Movement and then led the more radical splinter group known as the New European Order later that year. This group sought the creation of a new Rome–Berlin axis to unite Europe against capitalism and communism and in January 1953 set up a European Liaison Office under Amaudruz in Lausanne to co-ordinate the work of affiliated groups. He also came an early member of the Volkspartei der Schweiz but left the party over the issue of South Tyrol (where he was opposed to irredentism). Of all the groups involved Amaudruz was closest to Ordine Nuovo. Conferences were held irregularly, although membership was fluid and Amaudruz devoted much of his time to writing for journals such as Nation Europa.
 Passage 3:A native of Villabate, Alaimo studied at the Palermo Conservatory and then the L'Accademia di La Scala in Milan before making his début in 1977 at the Teatro Fraschini in Pavia as the title hero in Gaetano Donizetti's Don Pasquale. Shortly thereafter he joined the roster of singers at the Teatro Massimo in his home city. In 1980 he made his first appearance at the Piccola Scala in a production of Carlo Evasio Soliva's La testa di bronzo and performed for the first time at the Maggio Musicale Fiorentino as Radamanto in Giulio Caccini's Euridice. That year also marked his debut at the Festival de Ópera de Las Palmas and the Teatro Carlo Felice, two places he has sung with some frequency. In 1982 he performed for the first time at the Teatro di San Carlo, the Teatro dell'Opera di Roma, the Liceu, and the Rossini Opera Festival. He sang the role of Mustafà in Gioachino Rossini's L'italiana in Algeri for his United States debut at the Lyric Opera of Chicago in 1987. He reprised the role the following year for his first performance in the United Kingdom at the Royal Opera, London.
