What was the nature of her statement about the flight confirmation?

The statement about the flight confirmation is described as calm and factual, which suggests that she presented the information in a straightforward and collected manner. This implies that she was confident in the details she provided and was not expressing any emotions that might indicate distress, anxiety, or confusion. A calm and factual response typically indicates clarity and composure, allowing the listener to understand the information without the influence of emotional undertones.

In contrast, the other choices reflect varying degrees of emotional responses that do not align with a calm and factual demeanor. For example, a surprised attitude would imply an element of shock or unexpectedness, while being nervous suggests anxiety about the situation. Unclear communication would show a lack of confidence or knowledge regarding the information being shared, and a pessimistic tone would indicate doubt or negativity about the outcome. None of these attributes fit a calm and factual approach to delivering important information about a flight confirmation.
