CHORUS:
Thou hast withstood authority
A self-willed rebel, thou must die.

Answer:
Claudius and Gertrude ask Rosencrantz and Guildenstern about Hamlet's madness.
Explanation:
Rosencrantz and Guildenstern are Hamlet's friends from Wittenberg. Hamlet was unable to recover from his father's death. So, both Claudius and Gertrude wanted to know if Hamlet's madness was real. They wanted to help Hamlet and make him cheerful. Claudius wanted is friends to investigate why has his son changed a lot.
The tone of the conversation is shameful. Hamlet asks Rosencrantz and Guildenstern, if they had been sent by the king and the queen or they have come on their own. Both feel guilty when Hamlet asks them. They are loyal towards king and the queen and not Hamlet.
Even king and queen have mixed feelings about Hamlet.
