In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: On their way back from whitewater rafting with Juno and Beth, Sarah, along with Sarah's husband Paul and their daughter Jessica, are involved in a car accident when Paul is distracted. Paul and Jessica are killed, but Sarah survives.
One year later, Sarah, Juno, and Beth, as well as friends Sam, Rebecca, and newcomer Holly are reunited at a cabin in the Appalachian Mountains of North Carolina for a spelunking (caving) adventure. The next day, they hike up to a cave entrance and descend. While in the cave, Juno apologises to Sarah for not being there for her after the accident, but Sarah is distant.
After the group moves through a narrow passage, it collapses behind them, trapping them. After a heated discussion, Juno admits that she has led the group into an unknown cave system instead of the fully explored cave system that they had originally planned to visit, and that rescue is, therefore, impossible. She then tells Sarah that she led them into the unknown cave in the hopes of restoring their relationship, but Sarah rebuffs her.
Who does Sarah rebuff?
