For the question, "<span>In Act III, Scene 1 of the play, "Romeo and Juliet," Mercutio is killed by Tybalt.", this is an example of a SITUATIONAL IRONY. I hope this answer helps. Have a great day!</span>
I'd like to think it adds a tone of disgust. "Horrible vermin", as in "gross creature."
Participle is a verbal form that is used as if it were an adjective or adverb.
So, if the verb is, for example, "to bark" the participle would be"barking" as in "this barking dog"
and the correct answer is b. barking!
