Question: Can both War and Peace and Les vêpres siciliennes be arranged as five acts?

<P0-S0> The Cenci, A Tragedy, in Five Acts (1819) is a verse drama in five acts by Percy Bysshe Shelley written in the summer of 1819, and inspired by a real Italian family, the House of Cenci (in particular, Beatrice Cenci, pronounced CHEN-chee). <P0-S1>  Shelley composed the play at Rome and at Villa Valsovano near Livorno, from May to 5 August 1819. <P0-S2>  The work was published by Charles and James Ollier, in London in 1819 (see 1819), the Livorno edition, printed in Livorno, Italy by Shelley himself in a run of 250 copies. <P0-S3>  Shelley told Thomas Love Peacock that he arranged for the printing himself because in Italy "it costs, with all duties and freightage, about half of what it would cost in London." <P0-S4>  Shelley sought to have the play staged, describing it as "totally different from anything you might conjecture that I should write; of a more popular kind ... written for the multitude." <P0-S5>  Shelley wrote to his publisher Charles Ollier that he was confident that the play "will succeed as a publication." <P0-S6>  A second edition appeared in 1821, his only published work to go into a second edition during his lifetime. <SEP> <P1-S0> Les vêpres siciliennes ("The Sicilian Vespers") is a grand opéra in five acts by the Italian romantic composer Giuseppe Verdi set to a French libretto by Eugène Scribe and Charles Duveyrier from their work "Le duc d'Albe", which was written in 1838. <P1-S1>  "Les vêpres" followed immediately after Verdi's three great mid-career masterpieces, "Rigoletto", "Il trovatore" and "La traviata" of 1850 to 1853 and was first performed at the Paris Opéra on 13 June 1855. <SEP> <P2-S0> War and Peace (Op. 91) (Russian: Война и мир , "Voyna i mir") is an opera in two parts (an Epigraph and 13 scenes), sometimes arranged as five acts, by Sergei Prokofiev to a Russian libretto by the composer and Mira Mendelson, based on the novel "War and Peace" by Leo Tolstoy. <P2-S1>  Although Tolstoy's work is classified as a novel, the 1812 invasion of Russia by the French was based on real-life events, and some real-life people appear as characters in both the novel and the opera, e.g. Prince Mikhail Kutuzov and Napoleon Bonaparte. <SEP> <P3-S0> Tragédie en musique (Musical tragedy), also known as tragédie lyrique (French lyric tragedy), is a genre of French opera introduced by Jean-Baptiste Lully and used by his followers until the second half of the eighteenth century. <P3-S1>  Operas in this genre are usually based on stories from Classical mythology or the Italian romantic epics of Tasso and Ariosto. <P3-S2>  The stories may not have a tragic ending – in fact, they generally don't – but the atmosphere must be noble and elevated. <P3-S3>  The standard "tragédie en musique" has five acts. <P3-S4>  Earlier works in the genre were preceded by an allegorical prologue and, during the lifetime of Louis XIV, these generally celebrated the king's noble qualities and his prowess in war. <P3-S5>  Each of the five acts usually follows a basic pattern, opening with an aria in which one of the main characters expresses their feelings, followed by dialogue in recitative interspersed with short arias ("petits airs"), in which the main business of the plot occurs. <P3-S6>  Each act traditionally ends with a "divertissement", offering great opportunities for the chorus and the ballet troupe. <P3-S7>  Composers sometimes changed the order of these features in an act for dramatic reasons.
