Step-by-step explanation:
The rapid pace of the paragraph in question contributes to a sense of urgency and immediacy in the narrative. It reflects the protagonist's excitement and desperation to impress Juliana by borrowing the expensive car. This pacing is achieved through the use of short, clipped sentences and the character's stream of consciousness as he reasons, badgers, and pleads with his mother. This breathless tempo mirrors the protagonist's nervous energy and helps to immerse the reader in the emotional turmoil of the moment, highlighting how critical the situation is for him. Consequently, the rapid pace emphasizes the stakes of the situation for the protagonist, and his willingness to go to great lengths in the name of love or infatuation.
