I believe that the adverb phrase is "during the fifteenth century"
I believe the plot resolution occurs when Enrique and his mother are reunited. The two believe their reunion will result in what they've dreamed about, but all too soon reality sets in. Enrique cannot find it within himself to appreciate the sacrifices his mother made for him, and he in turn, is disappointed.
You use one by kind of like end of sentences but they are pausing. I think that's how you use them.
Asdfdsafsdaffffffdfassssssssssssssssafdsadfdsffffffffffffffffffffffff: True
I want to say the answer is A
My explanation:
I don't think it is B because the author mentions how he still hears the dragon in the wind so the knight keeps his sword sharp because he never knows if the dragon will show up again.
I don't think it is C because it suggests he is certain of a peaceful life. Although like mentioned before he keeps his sword sharpened for the thought of a dragon attacking so i think the peaceful life is not certain forever.
Finally I think the answer is not D because it does not portray in the story of the knight being a hero.
Therefor I believe A is left as the best option.
I hope this helps, have an amazing day :)
