The way the author makes the story is what actually affects all of that
I agree with your answers for 13 and 14. I think that the answer to 15 is A because the passage mentions this day's black fate and the woe that others will face in the future. If I remember correctly in this scene Romeo is talking about what repercussions Mercutio's death will have on the future.
The answer is C hope this helps
