I don't get the question, but if I had to guess what it'd have to be I'd say this statement is true. Many writers pushed boundaries, and experimented with what they were allowed to publish without restriction.
The chorus in an Ancient Greek play was extremely important because it helped the viewers to follow along. Often times it summarized what happened in a certain act/scene/play, which helped people who did not understand it to, well, understand it. It also often provided insight into characters minds. It told things about the characters that they could not tell about themselves, which could help the viewer predict what was going to happen in the upcoming scenes.
This all sounds like something they want YOU to decide.
Don't judge me because as far as I know I haven't let you borrow my shoes to walk in
Hope this Helps :)
