TASK DEFINITION: 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: Novelist Geoff and his wife Sally rent an isolated countryside bungalow to enable Geoff to finish his latest book without the distractions of life in London. On their arrival, they are horrified to find a dead man in the property; before they can report the discovery they are confronted by Duke, a gangland boss, and his henchmen who have, it transpires, been using the empty property as a hide-out for stolen valuables which they are planning to smuggle out of the country. A rival gangster, Juan, also has his eye on the goods and has discovered their whereabouts. The dead man is one of his minions.
Geoff and Sally are held captive, and matters take a turn for the worse when Juan and his men also arrive on the scene, forcing a stand-off between the two factions during which Geoff and Sally are roughly-treated by both sides. Duke starts to fall for Sally, and his obvious interest in her antagonises his girlfriend Rina. Eventually there is a bloody shoot-out between the rival gangs, with Duke's men getting the better of the exchange. Duke boards a plane to make good his escape with the valuables, but the plane is shot down by the jealous and vengeful Rina.

SOLUTION: Who worked for Juan?

PROBLEM: Passage: A woman's dead body is shown in a cluster of lantana bushes. 
Leon, a police officer, and Jane, have sex in a motel room. They part ways, and Leon and his wife, Sonja, attend Latin dance classes that the recently separated Jane is also taking.
Leon does not enjoy the classes. He is seen savagely beating a drug dealer during a bust. He has emotional issues but refuses to confront or admit to them. Sonja sees a therapist, Valerie, who has just published a book on her own daughter's murder 18 months ago. She and her husband, John, are barely on speaking terms; he later refers to their marriage as held together by their grief. She feels threatened by another patient, Patrick Phelan, who is having an affair with a married man, which forces Valerie to confront her own issues in her marriage to John.
Hoping to see Leon again, Jane purposely bumps into him outside the police station, and they have sex again despite Leon's reservations. Nik is upset that she is seeing someone because he is friends with her estranged husband, Pete, who wants to return home. Jane pairs up with Sonja in the next salsa class, which angers Leon, who ends their arrangement, which upsets Jane. She invites Nik over for coffee at the behest of Paula, with whom she is friendly and offers him money as they are struggling. Paula now starts to dislike Jane.
Valerie is coming home late one night and drives off the road. She is stranded and makes several calls to John, who does not answer. Finally, she is seen approaching a car coming along the road but never makes it home. Leon is the investigating detective on the case and looks into her office and notes.  Surprised at seeing his wife's name and file, he takes an audio recording of their sessions.

SOLUTION: Whose disappearance is Leon investigating when he finds tapes of his wife's therapy sessions?

PROBLEM: Passage: A divorcee, Zoe Jensen, moves to San Francisco from Omaha in an effort to rebuild her life. She has reluctantly left her young son back home with his grandmother until she is more financially secure. She joins a local church choir which has just gained a new, demanding choirmaster—retired music conductor Ephraim Adams. Adams challenges the choir to dramatically improve, creating discomfort for some of the members, particularly when he sets the high goal of performing Handel's Messiah for a Christmas concert. Meanwhile, the choir overcome personal setbacks as they all deal with personal issues.
A teacher by profession, Zoe soon learns no positions are available and that she lacks training to perform more readily available work. Living in an inexpensive flat, she brushes up her typing skills in order to gain employment before her mother wearies of looking after her son, who is growing anxious from his separation from Zoe.
Zoe receives her grounding at church, where an assortment of inner-city residents range from a former opera singer to a student seeking to educate himself for a life in a profession. The opera singer falls by the wayside when ego gets in her way, while the student is falsely accused of vandalism to the church organ simply because of his race, yet is vindicated by those who know and believe in him. Together, they persevere in the church choir. Along the way, Zoe finds an office job and, with the help of a bargain hunter, prepares a pleasant home for her son and herself.
Unexpected talent abounds within the choir. The amateurs give their best as ones who perform for the love of the music. This love extends far beyond the choir loft and is exemplified when the choir members band together to make the needed repairs to the organ pipes.

SOLUTION:
Who joins a local church choir with a new demanding choirmaster?
