What was a pretty blue vase doing way up there? i couldn’t reach it, obviously, so i moved over the chair with the tuxedo still on it, and then i went to my room to get the collected shakespeare set that grandma bought for me when she found out that i was going to be yorick, and i brought those over, four tragedies at a time, until i had a stack that was tall enough.

how does the narration shape oskar’s characterization in this excerpt?
his curiosity renders him extremely childish.
his literary references render him mature for his age.
his dramatic experience suggests great talent.
his plan for retrieving the case suggests great ingenuity.

His literary references render him mature for his age.

Explanation:

The excerpt comes from the novel Extremely Loud & Incredibly Close by Jonathan Safran Foer and is said by Oskar, a nine-year-old boy, who is also the narrator and protagonist of the story. For a boy of his age, it is not common to have the Collected Shakespeare set and know about their characters (like Yorick, a character of the play Hamlet), therefore these literary references render help portray him as someone intelligent and mature for his age.

impartial means: treating all rivals or disputants equally; fair and just.

i would say that impartial is agreeing with something, because impartial means to treat your rivals, arguments, and reasoning equally and fair. so if you rival says something, agreeing on it means you did the impartial.
