For the "Gift Of The Magi" provide two examples of dialogue from the characters in the story that support the climax you identified.
My climax: when they found out they sold their most prized possessions for gifts for each that are now of no use for them anymore

answer:

a. "there, said he, there is something for you."

explanation:

"said he" should not have been part of what is in the dialogue.

(you didn't attach a copy of the poem, but i'm answering as best as i can)

since a simile compares two unlike things using like or as, it kind of gives an item the ability to do something it can't.

example: "the player was like a tiger on the field"

in this sentence, the simile conveys the idea that the player was fast and strong, like a tiger.
