Final answer:
Randomizing between acts is most effective in a theatrical situation, adding variety and freshness to the performance and creating a sense of surprise and engagement.
Step-by-step explanation:
Randomizing between acts is most effective in a theatrical situation. This technique is commonly used in theater to create a sense of surprise and keep the audience engaged. By switching between different characters and perspectives, it adds variety and freshness to the performance, making it more dynamic and impactful. For example, in the play you mentioned with three people and two circles of microphones, randomizing between acts can help create a sense of anticipation and suspense. It keeps the audience guessing about who will speak next and adds an element of surprise when the characters finally meet and touch at the end. Overall, randomizing between acts adds an element of unpredictability to the performance, making it more interesting and engaging for both the actors and the audience.
