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.

[EX Q]: Passage: In 1990, Zappa was diagnosed with terminal prostate cancer. The disease had been developing unnoticed for ten years and was considered inoperable. After the diagnosis, Zappa devoted most of his energy to modern orchestral and Synclavier works. Shortly before his death in 1993 he completed Civilization Phaze III, a major Synclavier work which he had begun in the 1980s.In 1991, Zappa was chosen to be one of four featured composers at the Frankfurt Festival in 1992 (the others were John Cage, Karlheinz Stockhausen, and Alexander Knaifel). Zappa was approached by the German chamber ensemble Ensemble Modern which was interested in playing his music for the event. Although ill, he invited them to Los Angeles for rehearsals of new compositions and new arrangements of older material. Zappa also got along with the musicians, and the concerts in Germany and Austria were set up for later in the year. Zappa also performed in 1991 in Prague, claiming that "was the first time that he had a reason to play his guitar in 3 years", and that that moment was just "the beginning of a new country", and asked the public to "try to keep your country unique, do not change it into something else".In September 1992, the concerts went ahead as scheduled but Zappa could only appear at two in Frankfurt due to illness. At the first concert, he conducted the opening "Overture", and the final "G-Spot Tornado" as well as the theatrical "Food Gathering in Post-Industrial America, 1992" and "Welcome to the United States" (the remainder of the program was conducted by the ensemble's regular conductor Peter Rundel). Zappa received a 20-minute ovation. G-Spot Tornado was performed with Canadian dancer Louise Lecavalier. It was his last professional public appearance as the cancer was spreading to such an extent that he was in too much pain to enjoy an event that he otherwise found "exhilarating". Recordings from the concerts appeared on The Yellow Shark (1993), Zappa's last release during his lifetime, and some material from studio rehearsals appeared on the posthumous Everything Is Healing Nicely (1999).
[EX A]: In what city was Zappa's last professional public appearance?

[EX Q]: 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.
[EX A]: What is the last name of the person who was murdered?

[EX Q]: Passage: While students at South London's Elliott School in 2005, childhood friends Romy Madley Croft and Oliver Sim formed the xx with Jamie Smith and Baria Qureshi. Croft and Sim played guitar and bass, respectively, and dueted as the band's vocalists, while Smith programmed electronic beats for their songs, and Qureshi doubled as a keyboardist and additional guitarist. During late nights, Croft and Sim either shared lyrics with each other through instant messaging or rehearsed quietly with Smith and Qureshi in their bedrooms so they would not disturb the rest of the household. The xx were greatly influenced by American R&B producers such as The Neptunes and Timbaland, whose minimalist productions incorporated vocal harmonies, clapping percussion, unconventional samples, and pronounced beats. The band covered Aaliyah's "Hot Like Fire" (1997), Womack & Womack's "Teardrops" (1988), and other past R&B hits when they performed live and recorded their demos.After posting the demos on their Myspace page, the xx drew the interest of Young Turks, an imprint label of XL Recordings. They submitted the demos to XL's head office at Ladbroke Grove and were subsequently signed to a recording contract. The group worked with producers such as Diplo and Kwes, to no success before they were introduced to audio engineer Rodaidh McDonald by the xx's manager Caius Pawson, who gave him three CDs of demos titled "Early Demos", "Recorded in Rehearsal Space", and "What Producers Did Wrong". McDonald was impressed by the intimate quality and use of silence on the demos, which both he and the band felt may have challenged other producers who wanted to incorporate their individual tastes: "They'd worked with about four other producers before then that had—and no discredit to them—I guess they'd seen a lot of space to add a kind of stamp on. There was a lot of empty space in the xx's music, even then, in the 'Early Demos'. But we just found that the best stuff was the most sparse.".
[EX A]:
What are the first names of the people who shared lyrics with each other through instant messaging?
