Which type of drama allows the audience to suggest changes to the action in order to influence the outcome?

The correct answer is Forum theatre because it is specifically designed to encourage audience participation in the storytelling process. In Forum theatre, spectators are invited to suggest changes to the action or even replace actors on stage, allowing them to explore different outcomes and perspectives on the performance. This form of theatre is often used as a tool for social change, giving the audience a voice in addressing serious issues presented in the drama.

Interactive theatre, while it may engage the audience in various ways, typically does not focus on altering the narrative outcome. It may allow for interaction, but not necessarily in a structured manner that directly influences the plot as Forum theatre does.

Experimental theatre can include a wide range of non-traditional forms and may experiment with audience engagement, but it does not inherently provide the same framework for audience-driven outcomes that Forum theatre offers.

Improvisational theatre is characterized by spontaneous creation and can be engaging and interactive. However, it usually does not involve the structured feedback mechanism seen in Forum theatre. Each performance is primarily generated by the performers in the moment rather than involving audience suggestions to alter a pre-existing narrative arc.

Thus, Forum theatre stands out as the correct choice for this question, as it offers a clear platform for audience input regarding changes to the play's action
