Step-by-step explanation:
The chorus and prologue in a play often serve to provide context, summarize the previous act, and preview the upcoming events. They help set the tone, engage the audience, and offer insights into the unfolding narrative. While they may include entertainment elements, their primary function is to enhance the audience's understanding of the plot and create anticipation for what is to come. Singing beautiful songs is not their main purpose, but they may be used to convey emotions or enhance the atmosphere.
