What does the term 'beginners' signify during a performance?

The term 'beginners' during a performance typically refers to the time when actors make their entrance for the first scene. This moment is crucial as it marks the official start of the performance and sets the tone for the audience. It gives actors the opportunity to establish their characters and engage the audience right from the beginning. The other options, while relevant to the context of theater, do not accurately represent what 'beginners' signifies. For example, calling for stagehands or signaling to the audience to take their seats pertains to different aspects of production logistics rather than the initial entrance of actors. Similarly, referring to actors who are new to the production does not align with the term's use at the start of a performance. Understanding this term helps in grasping the structure and flow of a theatrical presentation.
