The answer is: Impersonating and remaining silent.
In the passage, the narrator describes Tom Stoppard's play "Rosencrantz and Guildenstern Are Dead." Both originally Shakespearean characters from "Hamlet," Stoppard develops them further in their own play, in which they "pass the time by impersonating other characters" and "remaining silent for long periods of time."
There's another question that's the exact same with people answering :)
whats the story? and what are the settings and plot?
