Answer:
Packing is a story about three friends who are getting ready to go for a journey. Thus, Packing summary will help students understand this story in a simplified form. It follows the packing session of three friends, Jerome, Harris, and George.
Actually, I am not too sure the question is well phrased. Translators do not decide on character development, conflict resolution or dialogue: they just need to stay faithful to the original text, those decisions are up to the original author.
so the best answer is "word choice", but that's not exactly "structural".
Unless the option of "dialogue" means the word choice in dialogue, but I don't think so.
I would say that a good answer would be "word order" or "grammatical construction".
