Great story! If you're still continuing on the story, I suggest adding a falling action for the conflict.
Answer:
It would have to be adolescents who have taken an interest in astronomy.
"They "lurk" in the shadows, "Mangling" stars and "gobbling" them up."
"<span>The feud between the Montagues and the Capulets is the conflict, and it is resolved by the deaths of their children" is the best option but using the word "solved" here is a bit misleading since the rivalry continued. </span>
A person who studies word origin and how the meanings change over time are Etymologists. So your answer would be C. The other options don't apply and a rootier as funny as it is there is no such thing.
Hope this helps, if you need anymore help or further explanation just let me know!! :)
