Answer:
The description shows her youthful sentimentality.
Frustration.
Step-by-step explanation:
In the first passage from Annie Frank's diary, she describes the things that they packed when they were to go into hiding. She mentions how they were asked to pack "our most important belongings", which for her, are her "memories". These materials of memories are her "diary, schoolbooks, some old letters" among others. She even stated that "Memories mean more to me than dresses", which is a definite indication of her youthful sentimentality even though she's still just a young girl.
Passage two is about a boy who is denied permission to go join his friends in the Go-kart. The words "exhaled loudly", "took a deep breath" and "gritted my teeth" perfectly show how frustrated he is in being denied the chance to enjoy with his friends. Despite trying to assure his father that "helmets, and speed limits, and supervision" are there for safety purposes, his father still refused to relent. This only adds to the frustrated feeling of the boy, who tried his best to try to persuade his father to allow him to go.
