All the things that Hamlet said after he asked Ophelia where her father was is already directed to Polonius. He already knew that Polonius was in the room, eavesdropping.
"Are you honest?", "Are you fair?" are the lines which Ophelia did not really understand why he was asking. This means that these lines are directed to Polonius.
"It hath made me mad" was said for them to believe that he's really crazy.
Could you put the quiz please?
Could you post the lines of two and four so I could see what they look like?
Answer: Passive voice
Explanation: The 'ed' at the end of the word gives away the fact that they are passive actions. A couple examples of that would be: They walked. She painted. He talked. Also 'was' is also a giveaway. 'Was' is a past tense word.
I hope that this helped you! :))
