Final answer:
The narrative style is changed by reporting Rina's questions about Karim's well-being and whereabouts, and Karim's explanation that he was at the book fair, thus accounting for his absence from home.
Step-by-step explanation:
To change the narrative style of the dialogue between Rina and Karim, we consistently shift the direct speech into reported speech to adapt the narrative standpoint. The narrative would focus on the contents of their conversation regarding well-being and activities.
