L'Histoire du soldat (The Soldier's Tale) is a theatrical work "to be read, played, and danced" ("lue, jouée et dansée ") by three actors and one or several dancers, accompanied by a septet of instruments. The piece was conceived by Igor Stravinsky and Swiss writer C. F. Ramuz based on a Russian folk tale ("The Runaway Soldier and the Devil") drawn from the collection of Alexander Afanasyev. Using only the above description and what you know about the world, "L'Histoire du soldat is to be played by a total of 10 actors." is definitely correct, incorrect, or inconclusive?
