Answer:
"but listen closely to what I am going to say".
Step-by-step explanation:
William Shakespeare's "Hamlet" deals with a young prince's desire to avenge the death of his father at the hands of his uncle. And through the character of Hamlet, the story delves into the themes of insanity, loyalty, love, betrayal, and relationships.
The given lines/ dialogue are from Act I scene v of the play where Hamlet encountered the Ghost of his dead father. The Ghost tells Hamlet to listen carefully to him, not to pity him but to "lend thy serious hearing / To what I shall unfold". This can be best paraphrased as the Ghost asking Hamlet to listen carefully to what he is about to say.
Thus, the correct answer is the second option.
