Question: Which opera has more acts, Faust or Mignon?
Context: Mignon, is a 1915 American silent drama film directed by William Nigh with production supervised by Alexander E. Beyfuss, based on the opera "Mignon" that was from the novel "Wilhelm Meisters Lehrjahre" by Johann Wolfgang von Goethe. Mignon Nevada (14 August 1886 – 25 June 1971) was an English operatic soprano.  She was born in Paris, daughter of the American operatic soprano Emma Nevada and her English husband Raymond Palmer.  She was named after the title character of the 1866 opera "Mignon", written by her godfather, French composer Ambroise Thomas.  Her voice was light and agile, and her mother trained her to be a coloratura soprano, although Sir Thomas Beecham thought this was a mistake, that she should have been a mezzo-soprano instead. Mignon is an "opéra comique" (or opera in its second version) in three acts by Ambroise Thomas.  The original French libretto was by Jules Barbier and Michel Carré, based on Goethe's novel "Wilhelm Meisters Lehrjahre".  The Italian version was translated by Giuseppe Zaffira.  The opera is mentioned in James Joyce's "The Dead" ("Dubliners") and Willa Cather's "The Professor's House".  Thomas's goddaughter Mignon Nevada was named after the main character. Faust is a grand opera in five acts by Charles Gounod to a French libretto by Jules Barbier and Michel Carré from Carré's play "Faust et Marguerite", in turn loosely based on Johann Wolfgang von Goethe's "Faust, Part One".  It debuted at the Théâtre Lyrique on the Boulevard du Temple in Paris on 19 March 1859, with influential sets designed by Charles-Antoine Cambon and Joseph Thierry, Jean Émile Daran, Édouard Desplechin, and Philippe Chaperon. Bridget Louise "Didge" Parker is a fictional character from the Australian soap opera "Neighbours", played by Eloise Mignon.  In 2007 the show was revamped to boost falling ratings in Australia.  As part of this, the show's focus returned to family dynamics and the character of Bridget and her family were created and introduced.  Bridget made her first on-screen appearance on 23 July 2007.  She arrived in Erinsborough from Sydney with her father and mother, Steve and Miranda.  During her time in "Neighbours", Bridget's storylines included being run over by Susan Kennedy, falling in love with Declan Napier, finding her birth mother and falling pregnant at seventeen.  In March 2009, the decision was taken to write the Parker family out of the show after both Mignon and Steve Bastoni quit.  Mignon wanted to return to her studies and she had had enough of "Neighbours".  Bridget died on-screen on 21 July 2009 after suffering internal injuries, which she sustained in a car crash.  The character was popular with viewers and her pregnancy storyline was voted the best of 2008 during a poll on the official website. Doktor Faust is an opera by Ferruccio Busoni with a German libretto by the composer himself, based on the myth of Faust.  Busoni worked on the opera, which he intended as his masterpiece, between 1916 and 1924, but it was still incomplete at the time of his death.  His pupil Philipp Jarnach finished it.  More recently, in 1982, Antony Beaumont completed the opera using sketches by Busoni which were previously thought to have been lost.  Nancy Chamness has published an analysis of the libretto to "Doktor Faust" and a comparison with Goethe's version. Faust is an opera by the German composer Louis Spohr.  The libretto, by Josef Karl Bernard, is based on the legend of Faust; it is not influenced by Goethe's Faust, though "" had been published in 1808.  Instead, Carl Bernard's libretto draws mainly on Faust plays and poems by Maximilian Klinger and Heinrich von Kleist.  Spohr's "Faust" is an important work in the history of German Romantic opera. Faust and Marguerite is a romantic opera in three acts, dating from 1855, based on the Faust legend.  The score was composed by Meyer Lutz.  The libretto was written by Henri Drayton based on the Johann Wolfgang von Goethe play "Faust".  The 1900 film "Faust and Marguerite" is an adaptation of the play.  It was directed by Edwin S. Porter, three years before he directed The Great Train Robbery. Mignon desires her fatherland (Dutch: "Mignon verlangende naar haar vaderland" ) is an 1836 painting by the Dutch-French artist Ary Scheffer.  The picture depicts a young woman Mignon, inspired from a character in Goethe's novel "Wilhelm Meister's Apprenticeship".  The 1866 Ambroise Thomas opera "Mignon" was based on the same character, and Scheffer's feminine representation of Mignon in a dress influenced her portrayal by Thomas.  The painting currently hangs in the Dordrechts Museum in Dordrecht, Netherlands. Miranda Parker (also West) is a fictional character from the Australian soap opera "Neighbours", played by Nikki Coghill.  In 2007, the show's focus returned to focus more on family dynamics and the characters of Miranda and her family were created and introduced to help boost falling ratings in Australia.  Miranda made her first screen appearance on 23 July 2007, along with her husband, Steve (Steve Bastoni) and her daughter Bridget (Eloise Mignon).  The family moved into Ramsay Street and Miranda became friends with many of her neighbours and was employed at both Erinsborough High and Lassiter's Hotel.  Her storylines included the arrival of her sister Nicola (Imogen Bailey), breaking up and later reuniting with Steve, having an affair with her old university lecturer, becoming a grandmother and the death of her daughter.  In March 2009, the decision was taken to write the Parker family out of the show after Mignon and Bastoni quit.  Miranda departed on 24 July 2009 with her husband, following their daughter's funeral.
