Final answer:
Without additional context, it's not possible to accurately determine whom Katherine is instructing to get the lights and unlock the windows. The answer requires specific knowledge of the narrative from which the question is taken.
Step-by-step explanation:
Katherine, a character referenced in the question, is giving instructions to someone to get the lights and unlock the windows, but without additional context, it's not possible to definitively answer who she is instructing. This type of question typically relates to a specific play, musical, book, or another form of narrative content, and the answer would depend on that context. If the instructions are from a notable work, you'd need to reference that text to identify whether it's Jack, Davey, Pulitzer, or Spot who is being instructed.
