Answer: Nothing but their children’s deaths could stop the parents’ anger.
What these lines state is that the parents' feud was continuous, and that, besides the children dying, nothing could stop it. In other words, nothing but the children's deaths could stop the parents' anger. This is true as we reach the end. It is only after the tragic death of Romeo and Juliet that the Capulet and the Montague are able to end their feud and leave their hate behind.
C. Double-meaning pun
In this pun, the word grave has a double meaning. It can refer to either the situation being serious or the hole in which the dead are buried. Both relate to the situation and therefore makes this a double meaning pun.
<em>Virgil is an appropriate guide for Dante at the beginning of "The Divine Comedy" because he is Dante's mentor and describes hell in the Aeneid. </em>When Dante enters Hell he is guided through the underworld by Virgil, who was a Roman Poet. Virgil wrote a heroic poem called "The Aeneid" in which talks about the descend into hell. Therefore by describing his poem and his work, Virgil works as Dante's mentor and guide through Hell and is an appropriate character to do so.
