In Act 1 of Hamlet, after speaking to his father's ghost, Shakespeare mainly shows that Hamlet has been affected by:
A. Hamlet speaks in confusing responses and acts oddly, demanding his friends swear on his sword.
This choice demonstrates Hamlet's altered state through his erratic behavior and peculiar demands. The fact that he speaks in confusing responses and acts oddly highlights the impact of the encounter with his father's ghost on his mental and emotional state. Additionally, his insistence on having his friends swear on his sword further emphasizes his distress and the depth of his reaction to the supernatural experience.
