Question

Read this excerpt from Extremely Loud and Incredibly Close.

One night, after what felt like a googolplex inventions, I went to Dad’s closet. We used to Greco-Roman wrestle on the floor in there, and tell hilarious jokes, and once we hung a pendulum from the ceiling and put a circle of dominoes on the floor to prove that the earth rotated.

How does the narration affect Oskar’s credibility in this excerpt?
His Greek and Roman references emphasize his intelligence.
His explanation of a pendulum emphasizes his maturity.
His fond recollections emphasize his genuine sincerity.
His description of his dad emphasizes his lack of stability.

Answer 1

His fond recollections emphasize his genuine sincerity.

The nostalgic, specific memories (wrestling, jokes, the pendulum and domino experiment) make his voice feel authentic and emotionally honest, which strengthens his credibility.
