Final answer:
Claudius's speech in Rosencrantz and Guildenstern are Dead is used as a set of instructions highlighting the insincerity and manipulation of Hamlet's supposed friends, mirroring the espionage culture in Elizabethan times and in Shakespeare's play.
Step-by-step explanation:
Tom Stoppard's Guildenstern are Dead uses Claudius’s speech from William Shakespeare's Hamlet as a set of instructions rather than as an expression of concern, emphasizing the characters’ insincerity towards Hamlet. This highlights the manipulative use of Rosencrantz and Guildenstern by Claudius to spy on Hamlet and the lack of a genuine relationship between them. Stoppard’s play acts as a commentary on the themes of manipulation and power present in Shakespeare’s original work, reflecting the espionage and suspicion that characters exhibit towards each other, and by extension, the critique of Elizabethan spy culture.
