Final answer:
A sitcom and a one-act play both aim to tell a complete narrative in a short time frame, focusing on tight plots and comedic situations to engage and amuse their audience.
Step-by-step explanation:
One similarity between a sitcom and a one-act play is that both are structured to tell a complete story within a relatively short and concise format. While a sitcom is typically a television genre, known for episodes that resolve their narrative within about 20 to 30 minutes, a one-act play also delivers its narrative within a similarly brief time frame, usually not more than an hour. Both forms rely on a tight plot and developed characters to engage their audience quickly and effectively, often focusing on creating hilarity and laughter. An essential element they share is the comedic aspect; playwrights utilize comedy to entertain and amuse audiences, whether through the comedic situations in a sitcom or the humorous dialogue and scenarios in a one-act comedy play. Examples include the lighthearted and humorous scenarios depicted in The Odd Couple, a play by Neil Simon, and popular sitcoms like Friends or The Golden Girls.
