Final answer:
A theatrical quart d'heure is a short play that presents complex ideas briefly, requiring concise storytelling.
Step-by-step explanation:
The theatrical quart d'heure, like Strindberg's The Stronger, is a term that refers to a short play that can present complex ideas and narratives within a brief amount of time. These types of plays can be particularly powerful as they condense emotions, conflicts, and themes into a compact performance, often without the need for elaborate stage decorations, props, or scenery. This form of theatre challenges playwrights and actors to convey meaning and engage the audience with limited resources and time.
