Question: Which play has more acts, La sonnambula or Maskarade?
Sentence (from "Antonino Votto"): This may have been an occupational hazard of working in the studio, as his live sets with Callas, including a "Norma" (December 1955, La Scala) and "La sonnambula" (1957, Cologne) are considered to be great performances.
Relevant evidence: No
