Final answer:
The provided text excerpts do not mention a character named Moira or relate to an inability to take something for 4 hours. Thus, a precise response cannot be given without the correct context.
Step-by-step explanation:
The question asks about a specific detail from a piece of literature, in which a character named Moira states that she can't endure something for 4 hours. From the provided excerpts, there is no mention of a character named Moira or a statement relating to an inability to take something for 4 hours. As such, it seems that the reference may pertain to a text that's not included in the given information. Therefore, without the correct contextual reference to Moira and her situation, it is not possible to provide an accurate answer to this question.
