Answer:
The appropriate follow-up question to ask this student would be the second one: "What are some specific examples of love causing violence in Romeo and Juliet?".
Step-by-step explanation:
This one should be the appropriate follow up question to ask this student because he affirmed that one of the themes in the story is that love can cause violence, so in order to dig more into his perception of the story it would be the more suitable question. This follow up question would help the rest of the class, and even the teacher, to dig more into the idea he expressed during the discussion about this particular writing of Shakespeare.
