Detailed Instructions: 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.
Problem:Passage: A Catholic priest, Father Brian Finn, has been dedicated to his calling since he was a child and now shares the duties of a New York parish with an older priest, Fr. Havel. Rabbi Jacob "Jake" Schram, best friends with Brian since childhood, is the youngest rabbi at his synagogue, focused on his work to the detriment of his private life, much to the chagrin of his mother, Ruth. The two men show a close bond, even in their professions, where the two are planning the opening of a jointly-sponsored community center. The pair reminisce occasionally about Anna Reilly, their childhood friend. She met Jake and Brian in middle school, after beating up a bully who was picking on them. The three became great friends, and enjoyed their childhood together. Unfortunately, Anna's father got a new job that resulted in the Reillys moving to California, and ultimately she lost touch with Brian and Jake.
Sixteen years later, Anna moves to New York for work and calls her old friends out of the blue; the friendship is rekindled. Anna and Jake begin sleeping together, but he is reluctant to be involved in a serious relationship with her because she is not Jewish, a fact which could compromise his relationship with his congregation and also with his mother (who disowned her eldest son for marrying outside the faith). Between the religious conflict and their desire to spare Brian's feelings, the relationship is kept mostly secret. As the relationship continues, Jake remains unable and unwilling to view the relationship as a serious one, despite Anna dropping hints to him about her having been recently taking a class (but refusing to tell him what kind of class it is), and her becoming visibly upset when they run into members of Jake's congregation while on a date and Jake introducing her only as "my old friend Anna".
