A.I. Explanation:

Option 1: "She doesn’t have many friends in the city."

Explanation: The text does not mention the speaker's number of friends in New York City. Instead, it focuses on the complexities of friendships and money, indicating that the speaker has friends but struggles with the etiquette of paying bills.

Option 2: "Her friends there are so rich that she cannot pay the bill."

Explanation: While the speaker acknowledges that her friends come from different financial backgrounds, the text does not state that she cannot pay the bill. The emphasis is on the confusion and etiquette surrounding money in friendships, not on her financial capability.

Option 3: "People there always avoid talking about the issue."

Explanation: This option is correct as the speaker explicitly states that the issue of money and friendships is not openly discussed, making it confusing and incomprehensible for her. This lack of communication contributes to her feelings of insecurity and confusion.

Option 4: "City life there are so hectic, leaving her no time to consider the problem."

Explanation: The text does not mention the hectic nature of city life as a reason for her feelings. Instead, it highlights the complexities of friendships and money, particularly the lack of discussion around these topics, which is the main source of her confusion.
