Answer:
Uhm where's the question?
answer:
knowing there would be spring
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.
C. I chose that rose for its sweet smell.
This sentence actually has two pronouns used as adjectives. The first is "that". It is an adjective because it describes which rose is being chosen. The second pronoun that's being used as an adjective is "its". "Its" tells us what the smell belongs to. Possessive pronouns are often considered possessive adjectives because they describe who or what is being owned. In this case the rose or "its" owns the smell.
