Problem: Background: Tosca (Italian pronunciation: ['toska; 'toska]) is an opera in three acts by Giacomo Puccini to an Italian libretto by Luigi Illica and Giuseppe Giacosa. It premiered at the Teatro Costanzi in Rome on 14 January 1900. The work, based on Victorien Sardou's 1887 French-language dramatic play, La Tosca, is a melodramatic piece set in Rome in June 1800, with the Kingdom of Naples's control of Rome threatened by Napoleon's invasion of Italy. It contains depictions of torture, murder and suicide, as well as some of Puccini's best-known lyrical arias.
Context: The French playwright Victorien Sardou wrote more than 70 plays, almost all of them successful, and none of them performed today. In the early 1880s Sardou began a collaboration with actress Sarah Bernhardt, whom he provided with a series of historical melodramas. His third Bernhardt play, La Tosca, which premiered in Paris on 24 November 1887, and in which she starred throughout Europe, was an outstanding success, with more than 3,000 performances in France alone.  Puccini had seen La Tosca at least twice, in Milan and Turin. On 7 May 1889 he wrote to his publisher, Giulio Ricordi, begging him to get Sardou's permission for the work to be made into an opera: "I see in this Tosca the opera I need, with no overblown proportions, no elaborate spectacle, nor will it call for the usual excessive amount of music."  Ricordi sent his agent in Paris, Emanuele Muzio, to negotiate with Sardou, who preferred that his play be adapted by a French composer. He complained about the reception La Tosca had received in Italy, particularly in Milan, and warned that other composers were interested in the piece. Nonetheless, Ricordi reached terms with Sardou and assigned the librettist Luigi Illica to write a scenario for an adaptation.  In 1891, Illica advised Puccini against the project, most likely because he felt the play could not be successfully adapted to a musical form. When Sardou expressed his unease at entrusting his most successful work to a relatively new composer whose music he did not like, Puccini took offence. He withdrew from the agreement, which Ricordi then assigned to the composer Alberto Franchetti. Illica wrote a libretto for Franchetti, who was never at ease with the assignment.  When Puccini once again became interested in Tosca, Ricordi was able to get Franchetti to surrender the rights so he could recommission Puccini. One story relates that Ricordi convinced Franchetti that the work was too violent to be successfully staged. A Franchetti family tradition holds that Franchetti gave the work back as a grand gesture, saying, "He has more talent than I do." American scholar Deborah Burton contends that Franchetti gave it up simply because he saw little merit in it and could not feel the music in the play. Whatever the reason, Franchetti surrendered the rights in May 1895, and in August Puccini signed a contract to resume control of the project.
Question: What is the background of Tosca?
Answer: In the early 1880s Sardou began a collaboration with actress Sarah Bernhardt, whom he provided with a series of historical melodramas.

Problem: Background: Meir David HaKohen Kahane (; Hebrew: myr dvd khn; August 1, 1932 - November 5, 1990) was an American-Israeli ordained Orthodox rabbi, writer, and ultra-nationalist politician who served one term in the Israeli Knesset. His work is influential on most modern Jewish militant and far right-wing political groups. Kahane spent years reaching out to Jews through published works, weekly articles, speeches, and debates on college campuses and in synagogues throughout the United States, and appearances on various televised programs and radio shows.
Context: In 1971, Kahane emigrated to Israel. When he moved to Israel, Kahane declared that he would focus on Jewish education. He later began gathering lists of Arab residents who were willing to emigrate for compensation, and eventually, he initiated protests which advocated the expulsion of Arabs from Israel and the occupied territories. In 1972, Jewish Defense League leaflets were distributed in Hebron, calling for the mayor to stand trial for the 1929 Hebron massacre. Kahane was arrested dozens of times. In 1971, he founded the Kach party. In 1973, the party ran for the Knesset (Israeli parliament) during the general elections under the name "The League List". The party won 12,811 votes (0.82%), just 2,857 (0.18%) short of the electoral threshold at the time (1%) for winning a Knesset seat. The party was even less successful in the 1977 elections, winning 4,836 votes.  In 1980, Kahane was arrested for the 62nd time since his emigration, and he was jailed for six months following a detention order based on allegations of planning armed attacks against Palestinians in response to the killings of Jewish settlers. Kahane was held in prison in Ramla, where he wrote the book They Must Go. Kahane was banned from entering the United Kingdom in 1981.  In 1981, Kahane's Kach party again ran for the Knesset during the 1981 elections, but it did not win a seat, receiving only 5,128 votes. In 1984, the Central Elections Committee banned him from being a candidate on the grounds that Kach was a racist party, but the Supreme Court of Israel overturned the ban on grounds that the committee was not authorized to ban Kahane's candidacy. The Supreme Court suggested that the Knesset pass a law that would authorize the exclusion of racist parties from future elections, and the Anti-Racist Law of 1988 was later passed.
Question: What else did he do?
Answer:
he initiated protests which advocated the expulsion of Arabs from Israel and the occupied territories.
