Answer:
Uncle Son
Step-by-step explanation:
This question is about "Inside out & Back again" written by Thanhha Lai, where she portrays her and her family's experience as refugees from Vietnam in the USA in 1975.
In this story, Kim Hà, the protagonist is forced to leave Vietnam with her family in the direction of the USA, since the war in Vietnam leaves the family without security and without economic conditions to maintain themselves with good living conditions. It was very difficult for Hà's mother to decide to change countries, especially to a completely different country with an unknown language, but Hà's uncle, Son, managed to convince her that this was the best thing to do.
