Problem:Question: How many years were there between the end of the Holocaust and the publication of Ubu Justicier au Premier Procès de Nuremberg? Passage 1: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.
 Passage 2:During the same period, he also served as Chief of Public Health for Portuguese India. He undertook a postgraduate course in parasitology in Kaiser Willhelm Institute fuer Biologie, Berlin, and at the Max Planck Institute, Potsdam, Germany from 1922–23. In 1922, at the age of 35, Mello became a Colonel in the Portuguese Army Medical Corps, achieving the highest rank in the medical military hierarchy of that time, exclusively through merits in the medical campaigns on Public Health which he carried out in Goa, Daman, Diu, and in Angola. Mello was the head of a Portuguese delegation to the World Leprosy Conference in Cuba and is known to have attended at least 40 World Conferences, including the All India Sanitary Conference in Lucknow (1914) and the Third Entomological Meeting in Lucknow (1914) where, at the invitation of the Governor-General of India, he lectured on medical mycology. His researches in tropical medicine brought him international fame and recognition as a world-renowned expert on the subject. Mello published more than 200 research papers on bacteriology in Portuguese, French and English journals. He founded the following medical journals in Goa, Boletim Geral de Medicina, Arquivos Indo-Portugueses de Medicina e Historia Natural, and Arquivos da Escola Medico–Cirurgica de Nova Goa. His work in French entitled, A la veille du Centenaire (On the eve of the Centenary) elaborated in great detail the contributions of Goa Medical College during the first hundred years of its establishment. Separate from his medical career, Mello also authored a book in 1946 on the Bengali poet, Rabindranath Tagore entitled O Cantico da Vida na Poesia Tagoreana (The song of life in the poetry of Tagore).
 Passage 3: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.
