What aspect of drama refers to how events are arranged in a cohesive manner?

The aspect of drama that refers to how events are arranged in a cohesive manner is structure. Structure is crucial in storytelling as it determines the sequence and arrangement of the plot, guiding the audience through the narrative effectively. A well-structured play will have a clear beginning, middle, and end, allowing for the development of themes and characters within a logical framework. This arrangement helps to build tension, create climactic moments, and ultimately lead to a resolution, ensuring that the story is engaging and comprehensible.

Thematic relevance focuses on the underlying messages or themes presented in the drama, which while important, does not directly address how events are organized. Character development pertains to the growth and transformation of characters throughout the play, which is influenced by the structure but is not synonymous with it. Performance style concerns the manner in which the play is presented to an audience, including elements like acting style, staging, and directorial choices, but again does not specifically address the arrangement of events in the narrative. Thus, the correct choice—structure—accurately captures the essence of how events are organized in a coherent and impactful manner.
