<span>Hamlet says early in the play that, in order to remain in Elsinore while he plans his revenge against Claudius, he may pretend to be crazy. People who might otherwise be suspcious of his motives will merely assume that the grief over his father's death is the cause of his erratic behavior.</span>
The correct answers would be "using contractions, slang terms, and colloquial expressions" and "using expressive punctuation". This way the writer brings the topic closer to the reader by making it "sound more like conversation". If you use "formal rules of grammar", it does not sound like a conversation, and "underlining words for emphasis" only draws your attention to those words. Mentioning your friend in the letter doesn't really affect anything.
