Extract the answer to the question from the following context. Question: Which of the following is not an Arab nationalist term: Arab homeland, Arab singers or Arab nation? Context: Nasser's street following was still too small to sustain his plans for reform and to secure him in office. To promote himself and the Liberation Rally, he gave speeches in a cross-country tour, and imposed controls over the country's press by decreeing that all publications had to be approved by the party to prevent "sedition". Both Umm Kulthum and Abdel Halim Hafez, the leading Arab singers of the era, performed songs praising Nasser's nationalism. Others produced plays denigrating his political opponents. According to his associates, Nasser orchestrated the campaign himself. Arab nationalist terms such "Arab homeland" and "Arab nation" frequently began appearing in his speeches in 195455, whereas prior he would refer to the Arab "peoples" or the "Arab region". In January 1955, the RCC appointed him as their president, pending national elections.

Extract the answer to the question from the following context. Question: What caused the revolutions? Context: In 1925, 78.26 rpm was chosen as the standard because of the introduction of the electrically powered synchronous turntable motor. This motor ran at 3600 rpm, such that a 46:1 gear ratio would produce 78.26 rpm. In parts of the world that used 50 Hz current, the standard was 77.92 rpm (3,000 rpm with a 77:2 ratio), which was also the speed at which a strobe disc with 77 lines would "stand still" in 50 Hz light (92 lines for 60 Hz). After World War II these records were retroactively known as 78s, to distinguish them from other newer disc record formats. Earlier they were just called records, or when there was a need to distinguish them from cylinders, disc records.

Extract the answer to the question from the following context. Question: Which of the following is not the name of a piece of music: Flight of the Bumblebee, A Space Odyssey, or Symphony No. 5? Context: Certain staples of classical music are often used commercially (either in advertising or in movie soundtracks). In television commercials, several passages have become cliched, particularly the opening of Richard Strauss' Also sprach Zarathustra (made famous in the film 2001: A Space Odyssey) and the opening section "O Fortuna" of Carl Orff's Carmina Burana, often used in the horror genre; other examples include the Dies Irae from the Verdi Requiem, Edvard Grieg's In the Hall of the Mountain King from Peer Gynt, the opening bars of Beethoven's Symphony No. 5, Wagner's Ride of the Valkyries from Die Walkure, Rimsky-Korsakov's Flight of the Bumblebee, and excerpts of Aaron Copland's Rodeo.
