instruction:
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.
question:
Passage: Justin Quayle, a low-level British diplomat and horticultural hobbyist posted in Kenya, learns that his wife Tessa was found dead in the veld. Tessa has been murdered at a crossroads along with her Kenyan driver. Her colleague, Dr. Arnold Bluhm, initially suspected of her murder, is then found to have been murdered on the same day as Tessa. Various rumours abound that the two were having an affair; it is later revealed that Bluhm was gay.
In flashbacks, we see how in London, Justin met his future wife Tessa, an outspoken humanitarian and Amnesty International activist. He falls in love with her, and she persuades him to take her back with him to Kenya. Despite their loving marriage, Tessa keeps from Justin the reason why she approached him in the first place: to investigate a suspicious drug trial in Kenya and expose it. When Tessa starts getting too close to uncovering the malpractices of an influential and powerful pharmaceutical company, she and her colleague are brutally murdered.
As the mystery surrounding his wife's death unfolds, Justin becomes determined to get to the bottom of her murder. He soon runs up against a drug corporation that is using Kenya's population for fraudulent testing of a tuberculosis drug. The drug has known harmful side effects, but the corporation completely disregards the well-being of its impoverished African test subjects.
answer:
What is the last name of the person who was murdered?

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


question:
Passage: Whether the move to America was Julius's idea or his son's is unknown. A leading Florida property firm had branches in several English cities including Bradford; in an article on Delius's time in Florida, William Randel conjectures that either Julius Delius visited the Bradford office and conceived the notion of sending his wayward son to grow oranges in Florida, or that Fritz himself saw it as a way to escape the hated family wool business and suggested the idea to his father. Delius was in Florida from the spring of 1884 to the autumn of 1885, living on a plantation at Solano Grove (29°52′29″N 81°34′34″W) between Picolata and Tocoi on the Saint Johns River, about 35 miles (55 kilometers) south of Jacksonville. He continued to be engrossed in music, and in Jacksonville he met Thomas Ward, who became his teacher in counterpoint and composition. Delius later said that Ward's teaching was the only useful music instruction he ever had.Delius later liked to represent his house at Solano Grove as "a shanty", but it was a substantial cottage of four rooms, with plenty of space for Delius to entertain guests. Ward sometimes stayed there, as did an old Bradford friend, Charles Douglas, and Delius's brother Ernest. Protected from excessive summer heat by river breezes and a canopy of oak trees, the house was an agreeable place to live in. Delius paid little attention to the business of growing oranges, and continued to pursue his musical interests. Jacksonville had a rich, though to a European, unorthodox musical life. Randel notes that in local hotels, the African-American waiters doubled as singers, with daily vocal concerts for patrons and passers-by, giving Delius his introduction to spirituals. Additionally, ship owners encouraged their deckhands to sing as they worked. "Delius never forgot the singing as he heard it, day or night, carried sweet and clear across the water to his verandah at Solano Grove, whenever a steam-ship passed; it is hard to imagine conditions less conducive to cultivating oranges—or more conducive to composing."While in Florida, Delius had his first composition published, a polka for piano called Zum Carnival. In late 1885 he left a caretaker in charge of Solano Grove and moved to Danville, Virginia. Thereafter he pursued a wholly musical career. An advertisement in the local paper announced, "Fritz Delius will begin at once giving instruction in Piano, Violin, Theory and Composition. He will give lessons at the residences of his pupils. Terms reasonable." Delius also offered lessons in French and German. Danville had a thriving musical life, and early works of his were publicly performed there.
answer:

What is the full name of the person who, in late 1885, left a caretaker in charge of Solano Grove and moved to Danville, Virginia?
