Concept:An interlude is a short dramatic or musical piece inserted between the main sections of a larger performance.
Explanation:In drama, an interlude originally meant a light entertainment performed between the acts of a longer play.
Its purpose was to amuse the audience while the main play paused or the stage was being prepared.
The word itself suggests something that comes “between” the main events of a performance.
The other options do not fit this meaning.
An “in medias res” is a narrative technique where a story begins in the middle of action, not a short play.
An “incantation” is a chant or spoken formula used in ritual or magic, not a theatrical entertainment.
A “deus ex machina” is an unexpected device or character that resolves a plot, not a short performance between acts.
Therefore, the short play performed between the acts of a bigger play is correctly called an interlude.
