Answer:
The writing of "The Isle of Dogs" by Ben Jonson and Thomas Nashe.
Step-by-step explanation:
In the given excerpt from "The Time Traveler's Guide to Elizabethan England", the author talks about Ben Jonson. He gave a description of the life of Jonson, the events in his life.
But most of all, he also gave the detail about how the writing of the book The Isle of Dogs led to a drastic event in history. Co-authoring the book with Thomas Nashe, the book was deemed "so slanderous and offensive that the privy council orders the closure not just of the play but of every theatre in London."
Thus, we can safely say that the writing of the book most directly caused the council to order the closure of all theatres in London.
