Final answer:
To convert 'You needn't go now?' into an affirmative statement, it becomes 'You can stay now.'
Step-by-step explanation:
The question 'You needn't go now?' when turned into an affirmative statement would be 'You can stay now.' This implies that there is no necessity for the person to leave at the current moment and they are free to remain where they are. It can be inferred from the dialogue in the given references that decisions regarding leaving or staying are central to the context and often reflect varying levels of distress, reluctance, or accommodation. For instance, a speaker might feel compelled to remain due to someone's need or feel pressure to leave to fulfill an obligation elsewhere.
