Answer:
The correct answer is the third quotation : "When I told them I planned to bring Mariah, I didn’t hear back from them. 'Had a blast skating, and Mariah fell only twice,' I captioned our selfie."
Explanation:
In the first paragraph, Jordyn expresses that these two characters (Jordyn and Mariah) belong to different worlds, worlds that can never get together.
Little by little by working together, Jordyn says she begins to like this new girl from camp. They were both making an effort to make their worlds meet by doing with the other girl likes doing.
The moment when we can realize that Jordyn truly values her new friend is when she decides to take Mariah skating with her "crew". They don't show up because they are not interested in Mariah. Jordyn posts a selfie of the two of them with a captions that reads: “Had a blast skating, and Mariah fell only twice." This means she doesn't mind her friends don't approve of her new friend from camp. She even posts a picture showing to her crew that she had a lot of fun. Going against her crew wishes shows how Jordyn greatly values her friendship with Mariah.
