Final answer:
In a hypothetical scenario, Vance could have sneaked out of detention by waiting for a moment of distraction, and then quietly and stealthily moving towards the exit. However, the exact method depends on the specific situation and details in the text.
Step-by-step explanation:
Without more context, it's difficult to provide a precise answer to 'How did Vance sneak out of detention?'. However, commonly in stories, a character might sneak out of a situation such as detention by waiting for a moment of distraction. For example, Vance might have waited until the attention of the supervising teacher was focused elsewhere, such as on another student or perhaps something occurring outside of the room. Then, moving slowly and quietly, Vance could have sidestepped towards the exit, staying out of sight where possible, and then slipped out of the door. Keep in mind that this is all conjecture and the precise method used by Vance would depend on the specific situation and details provided in the text.
